Abstract
In this paper we investigate the nexus between housing price and mortgage lending in
China We analyse a sample of 28 Chinese domestic commercial banks during the period
2003-2009 Our results suggest a reserve causality between mortgage lending and
housing prices The approaching urbanisation throughout China contributes substantively
to the credit boom We find a distinct behavior of the economical housing market in
which the housing price and mortgage credits affect each other adversely The national
inflation rate is of more consideration by potential high grade and economical house purchasers We also find that the monetary policy has a greater impact on the mortgage
lending than banksrsquo characters Raising bank reserves is a relatively effective instrument
to control the mortgage credit boom On the other hand the interest rate functions
better in tempering property prices Our findings have important policy implications and
account for the existing monetary policies which are implemented in China

1 Introduction
Over the past decade both the mortgage market and property sector have
experienced a dynamic change The current financial crisis which starts from
2008 and makes the whole banking industry suffer is largely attributed to the
meltdown of US subprime mortgage market The rapid growth of real house
prices and mortgage debts has been extensively documented across many
countries (Milesand and Pillonca 2008 Wolswijk 2006) Meanwhile China as
one of the largest emerging markets has witnessed soaring property price and
mortgage credit boom in the domestic market (Liang and Cao 2007) Figure 1
and figure 2 illustrate the movements of mortgage loans and property prices
in mainland China respectively In an international context it is a stylized fact
that the amount of bank lending is strong correlated to the property price
Many existing empirical studies highlight a strong correlation between bank
lending and property prices (Hofmann 2003 Gerlach and Peng2005
Fitzpatrick and McQuinn 2007 Davis and Zhu 2010) China is an interesting
example which also experienced mortgage boom and soaring property prices
She provides a representative figure of emerging property market which grows
and develops out of nothing during the past decades At the same time China
also experienced a tremendous reformation in the banking and house
financing sectors In this paper we focus on the relationship between the
outstanding mortgage loans and housing prices In addition we test the real
effects of bankrsquos characteristics and monetary policies

The development of Chinese commercial mortgage market began to
accelerate from 1998 in which year Peoplersquos Bank of China authorizes all
domestic commercial banks to issue household mortgage loans From then on
the Chinese government has embarked upon an effort to introduce
market-oriented mechanisms into property financing system eg financial
leverage through commercial banks All these measures have promoted and
contributed to the housing reform in mainland China (Zhang 2000)
Meanwhile commercial banks also recognize the residential mortgage credits
as health asset in their portfolio given the lower default rate of loans to
individual mortgagors than state-owned entrepreneurs (Deng and Fei 2008)
Accordingly the competition is brought about into house financing market
Although the marketised housing mortgage was first introduced in 1998 the
outstanding mortgage loans soared from 51 billion Yuan in 1999 to 6060
billion Yuan at the end of 2010 The mortgage to loan ratio for all financial
institutions increased from 059 in 1999 to 1265 at the end of 2010
During the same period the property prices increase with the volume of
outstanding mortgage loans during the period 1999-2009 except for 2008 in
which year the influence of financial crisis spread to China Except for
commercial mortgage loans from financial institutions Housing Provident
Fund (HPF) is an alternative way which provides the participants lower
interest rate than commercial banks1
1Since the HPF loan is often not sufficient most house buyers prefer to apply to both HPF and commercial
mortgage loansYeung andHowes (2006) reviewedthe role of the HPF infinancing affordable housing development
4
The Chinese mortgage market is featured in two aspects First a uniform and
adjustable mortgage rate is set by the Peoplersquos Bank of China for all
mortgagers2 Once a new mortgage rate is announced it applies to all types
of mortgages including existing ones Second there has been not yet mature
secondary mortgage market Until now only two Mortgage-Backed Securities
(MBS) have been issued in China3 Consequently Chinese mortgage holders
have limited alternative way to invest and then are sensitive to the change of
mortgage rate (Deng et al 2009) That accounts for the high rate of
prepayment in China
The paper is organized as follows Section 2 reviews theoretical and empirical
literature on the relationship between mortgage lending and property price
and highlights the major contributions of my work Section 3 describes the
data methodology and variables employed in the analysis The empirical
results are presented in section 4 Section 5 concludes this paper
2 Literature Review
Various models and empirical frames have been proposed to explain the close
relationship between bank lending movements and property prices which is
also supported by abundant cross-country evidence (Tsatsaronis and Zhu 2004
in China in detail 2 Since 2005 commercial banks can set individual rate which cannot be lower than 90 percent of the rate set by
the Peoplersquos Bank of China 3According to the report by the Peoplersquos Bank of China only China Construction Bank (CCB) are authorized to
issue MBS in the domestic inter-bank Bond Market amounting to yen3018 billion and yen 416 billion respectively

Eacutegert and Mihaljek 2007 Lacoviello and Minetti 2008 Goodhart and Hofmann
2008 Davis and Zhu2010) and the indications of individual countries such as
the USA (Capozza et al 2002) Spain (Gimeno and Martinez-Carrascal 2006)
Ireland (Fitzpatrick and McQuinn 2007) and China (Liang and Cao 2007)
Hofmann (2003) and Basurto et al (2006) suggest a bi-directional causality
between housing prices and bank credits However Goodhart and Hofmann
(2004) Gerlach and Peng(2005) find that the change of property prices have a
significant impact on bank lending without the real effect of bank credits on
property prices By contrast Liang and Cao (2007) investigate the case of China
and suggest a unidirectional causality from bank lending to property prices
which differs from previous empirical work about developed economies
Although the empirical analyses above are attractive and involve standard
ldquobubble bustersrdquo such as income or interest into their frameworks they are
hard to explain the real effects theoretically and rather ad hoc There are two
alternative models in the literature to systematically and theoretically
interpret the housing prices The first one is an inverted demand model which
includes the per capita housing supply and an index of credit conditioning as
additional explanatory variables and then provides better theoretical
foundations (Muellbauer and Murphy 1997 Meen 2002) This model is
appropriate for those countries in which the housing supply rockets up
considerably The alternative model is the house price-to-rent model (Ayuso
and Restoy 2006) It assumes the house rent-to-price ratio only depends on the
6
user costs and investigates the arbitrage between occupied and rental housing
market It is attractive to those countries such as the US in which rent is
market-oriented
Although the previous work using a bank-level data is not much Davis and Zhu
(2009) employ a sample of micro data from 904 banks in 17 countries during
the period 1989-2002 and find strong correlation between bank credits and
commercial property in those countries which experienced crises linked to
property loss by banks To my knowledge there has been no previous research
that investigates the Chinese case using a bank level data Our paper
supplements the existing literature in three ways First a unique bank-level
mortgage data - which consists of a sample of 28 Chinese domestic
commercial banks during the period 2003-2009 - is employed for the empirical
analysis Second we estimate the nexus between the mortgage credits boom
and four different housing prices Finally we include the urbalisation and
monetary policy indices to capture the effects of socio-demographic change
and regulatory constraints respectively
3 Data Description and methodology
31 Methodology
We aim to investigate the interrelation between bank mortgage and property
markets and test two hypotheses below
7
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
H2 Does The process of urbanisation have a positive effect on the mortgage
credits
In addition along with the credit boom the central bank has carried out
different monetary policies to intervene with the property and mortgage
market indirectly We also test the real effect of interest instrument and
required reserve ratio on both housing prices and mortgage lending In order
to test the hypotheses above we first propose the model of banksrsquo and
borrowersrsquo behavior in the context of house financing through mortgage
lending
Borrowerrsquos behavior
Assume there are two goods house occupation and a composite consumption
good We use Cobb-Douglas utility function to analyze borrowerrsquos behavior
1U X Y
Where U denotes the utility of a borrower X is the consumption of composite
good and Y is the house occupation of the household Considering the
monotonicity of utility function we take logarithmic transformation and α is
the indicator of house purchase intension
log log (1 ) logU X Y
Suppose the household use mortgage loan to finance the house occupation
8
and dispensable income to support the consumption of house service and
composite good Then we can get borrowerrsquos maximum utility under the
constraint of dispensable income
max log log (1 ) logX Y U X Y
st [1 ( )]X r i M I
M P Y
Where I represents the dispensable income of borrower r is the real interest
rate of individual banks i denotes the inflation rate M is the total mortgage
loans P is the house price Optimal allocation is solved through Lagrange
function
log (1 ) log [ (1 ) ]L X Y X r i P Y I
Thesis of the Lagrange function is shown as follows
0
1(1 ) 0
(1 ) 0

X X
Lr i P
Y Y
LX r i P Y I
By solving the linear equation system above with three unknowns which are P
M and λ respectively we get
(1 )
(1 )
IM P Y
r i
From the equation of M we argue that Mortgage demand increases with
9
borrowerrsquos income and house price but decreases with house purchase
intension and the interest rate In addition inflation has a positive impact on
mortgage demanding
Bankrsquos behavior
We assume the whole deposits of banks are interest-bearing assets She
allocates a proportion of its total Deposits on mortgage loans The total
mortgage lending is denoted as Y which is equal to consumersrsquo demanding of
mortgage loans The Loan_To_Deposit ratio is θ Then the mortgage can be
rewritten as Y D An individual bank enjoys an interest rate r on its
mortgage loans On the other hand she has to pay out the interest rate dr on
its deposits The lending business of individual bank incurs costs C which is
explained as a quadratic function 2( ) (1 )C Y c Y The individual bank aims to
maximize its total profits which is denoted as Then the maximization
function can be outlined as follows
2max [1 ] dr M N c Y r D
with M N P Y
D M
Then we plug M and D into our target function and get

supply provided by the bank increases with its NIM the number of mortgagers
(N) housing price (P) and decrease with its Loan_To_Deposit ratio (θ)
Econometric approach
Based on the theoretical analysis above we propose an empirical framework
to estimate the movements of mortgage lending as follows
1 1 1Mortgage Pop Interest Rate Inflation NIM LTD House Prices it it it it i t i t it itf RR
The index of potential mortgagers is Pop which is estimated by the
percentage of urban population to total population in China It also refers to
the effect of urbanization and internal migration Inflation and House Prices
are macroeconomic factors which have potential impact on the mortgage
market NIM LTD represents the Net Interest Margins and Loan to Deposit
ratio These variables reflect the characteristics of individual banks Interest
Rate and RR the Required Reserves of banks are proxies of monetary policy
constraints
11
Previous research also indicates that House price is rather an endogenous
variable and driven by market factors including creditmortgage rationing
Inverted demand equation is then widely used to estimate the house prices
We employ a simplified version of the house price model which is proposed by
Muellbauer and Murphy (1997) 4
( )HS Pop f I D
( )eP r P P
Where is the real user cost of housing services P is the real housing price
and eP P is the expected appreciation rate of housing price5 Muellbauer
and Murphy (1997) also pointed out that a proxy for creditmortgage
rationing is often included in the measurement housing price Substituting the
user cost into the housing stock function and involve the proxy of credit
conditions we can get the invert demand function to obtain the estimation of
P
( _ )eP f HS P P I credit rationing
Where HS eP P and I represent the housing stock expected appreciation
rate of housing price and the Income respectively Here in our frame we
employ the ratio of house price to house rental index to proxy the
appreciation rate Although the down payment ratio is a good and popular
index of credit rationing Chinese housing financing system has not
4Dougherty and Order investigate the measurement of the housing cost through two alternative approaches
They deduct the capital cost by maximizing household utility or implicit rent of the landlord and come up with the same results 5 Murphy also pointed that the long-run price-to-rent ratio can be estimated by real user cost and loan-to-value
ratio
12
experienced significant change of this ratio However the change of Mortgage
can partially reflect the bankrsquos credit rationing The increase of mortgage loans
is associated with loose credit rationing and lower interest rate Therefore we
employ the change of mortgage to proxy the credit rationing index Taking
into account the estimation of mortgage lending we form a simultaneous
equation system as follows to estimate mortgage loans and endogenous
housing prices Considering the bank-level mortgage loan data panel data
approach and two-stage least squaresInstrument variable method are
employed in our estimation

32 Data description
Compared with developed countries Chinese mortgage market has a relative
short history and therefore limited data available In this paper an unbalanced
panel of annual mortgage loans of Commercial Banks is employed for the
analysis 6 Our sample consists of all State-Owned-Banks (SOBs)
Joint-Stock-Banks (JSBs) and major City-Commercial-Banks (CCBs) The sum of
mortgage credits in our sample covers more than 80 of total mortgage
outstanding which makes our sample highly representative Therefore fixed
effect model is more appropriate to control for the individual heterogeneity
6Since the financial reform in Chinese banking sector and new enforcement of information disclosure by China
Bank Regulatory Commission the mortgage data for some banks in early years is not available
13
Next we carefully select conventional explanatory variables for our empirical
analysis so as to ensure our estimation is robust to omitted variables The
variables included in the empirical framework are described in groups as
follows The macro data which is collected from the Peoplersquos Bank of China
and National Bureau of Statistics of China Mortgage loans bank specific
variables and house prices are collected from ALMANAC OF CHINAS FINANCE
AND BANKING which is the official publication of Peoplersquos Bank of China
Dependent variables
We are more interested in the movements of mortgage loan and housing
prices within a given year Therefore the change of mortgage loans of
individual banks and housing prices are employed as the dependent variable
In addition log transformation of mortgage loans is employed In order to
avoid heteroscedasticity
Macroeconomic explanatory variables
Although GDP is a popular variable to assess the macroeconomic situation
(Liang and Cao 2007 Davis and Zhu 2010) a large body of literature explores
the impact of disposable income as an alternative McQuinn and OrsquoReilly
(2007) Hill and Gan(2008) established the relationship between income and
house price from both theoretical and empirical sides7 Urban disposable
7Other existing researches also corroborate the potent influence of household income on the dynamics of
housing prices see Jud and Winkler 2002 Gimeno and Martinez-Carrascal 2006 Bourassa and Hoesli2006
14
Income is appropriate to analyse the movement of property prices We
employ the national average deposable income for SOBs and JSBs given their
nationwide business line and local average disposable income for CCBs
considering their local market focus In addition urban disposable income is
log transformed in order to avoid heteroscedasticity problem8
Urbanization is another factor of our interests that may drive the movement of
mortgage credits Over the past decade China has experienced a dramatic
process of industrialisation and urbanisation And Comparing with
industrialisation Chinas urbanisation developed more rapidly (Zheng et al
2007) More and more new immigrants moved into cities Taking into account
more potential home buyers a higher volume of mortgage loans is expected
We use the percentage of urban population to total population to capture the
effect of urbanisation
House stock refers to the number of existing residential units It is also
considered as the response to the land-use regulation through the elasticity of
new housing supply (Quigley and Raphael 2005) In our empirical analysis we
employ the number of house sales to proxy the housing stocks Furthermore
the expected rate of appreciation of house prices reflects consumersrsquo
Nevertheless some other literatures are not in favor of this point of viewGallin (2006) analyzes a panel of 95 US metropolitan areas over 23 years and does not find evidence of long-run relationship between the property prices and income in level This result is also proved by Tsatsaronis and Zhu (2004) who find little impact of household income on housing prices in their cross-country analysis 8No evidence of long-run relationship between the level of property prices and level of income is found by in
Gallin (2006) Therefore we intend to investigate this issue by involving log transformation of income (Ermini and Hendry2008)
15
purchase intention of houses In this empirical framework the ratio of house
price index to rental price index is used to proxy the house prices appreciation
And it is lagged one period to reduce simultaneity
Bank specific explanatory variables
The interest rate as an indicator of monetary policy is another widely
accepted explanatory variable9 It is calculated as the ratio of total interest
revenue over to interest bearing assets of individual banks A declining interest
rate environment contributes to the increasing demand for real estate and
housing investment (Greenand Shoven1986 Kearl1979 Tsatsaronis and Zhu
2004) In terms of Chinese housing market Liang and Cao (2007) suggest that
the property price movements have no sensitivity to the change of the real
interest rate By involving the rate of interest we reinvestigate to what extend
the raising interest rate can affect the mortgage credits and property prices
The required reserves are required to hold by commercial banks in the form of
deposits at the central bank Over the past decade along with the soaring
property prices and mortgage credit boom the central bank has raised the
required reserve ratio several times from 6 in 1999 to 20 in 2011 It is
viewed as another frequently used monetary policy other than the interest
9Hofmann (2003) concludes that real interest rate is more closely associated with property prices than with bank
lendingWolswijk (2006) and Eacutegertand Mihaljek (2007) confirm the negative effect of interest rate on houses prices in 15 EU countries and Eastern Europe
16
rate in China We explore in our paper whether the change of bank required
reserves has an impact on the movements of properties and mortgage credits
And we will compare the real effect of interest rate and required reserve ratio
We use one period lag transformation to reduce simultaneity
Loan_to_asset ratio is an important measure of balance sheet risk of individual
banks Since banks can not grant credit at all costs they need to conduct credit
audit and monitoring effectively in order to maintain low levels of
non-performing loans and increase margins (Abreuand Mendes 2001) In spite
of a positive relationship between Loan to deposit ratio and bank profitability
a high loan to deposit ratio is a warning sign of bankrsquos loan risk and then
discourage credit expansion In order to reduce simultaneity one period
lagged Loan_to_asset ratio is employed to capture the real effect of banksrsquo risk
taking behavior NIM is referred to as the net yield on interest-earning assets
and an indicator of profitability of a bankrsquos lending activities10 In addition
NIM is also a proxy of bank performance and profitability for Chinese banking
sector (Matthews 2009) We would like to test the favor of individual banks on
mortgage profits
Property prices as explanatory variables
The growth of four different property prices is employed in the empirical

Hanweck and Ryu (2005) capture NIM dynamics in response to unanticipated credit and find negative relationship between NIM and expected credit loss

framework They are condominium price the average real estate price and an
indicator of the whole property market residential price the indicator of solo
residential market high_grade houses price a measure of luxury and high-end
real estate market and economic houses price the price of affordable houses
for low-and-medium wage households Crone and Voith(1992) compare five
popular methods to estimate house price appreciation and conclude that the
mean sales price is least affected by the sample size and more accurate than
other estimating methods We aim to investigate the impact of different prices
on the change of mortgage separately The same as disposable income and
mortgage outstanding property prices are converted to logarithm form in
order to avoid heteroscedasticity problem Figure 4 illustrates the movements
of property prices in four separate real estate market
4 Results
41 Mortgage loans
The determinants mortgage lending are illustrated in table 3 from which we
test our hypotheses proposed in section 31
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
Our findings so far suggest that the volume of outstanding mortgage loans
increases with housing prices expect for the economic housing market which
is not surprising and in line with most recent evidence of developed countries
18
However we argue that the elasticity of condominium (and residential) price
to mortgage credits is around 17 which is much higher than that of other
countries 11 The condominium and residential prices illustrate a similar
impact on the mortgage lending It is simply because after the housing
reformation in 1998 all work units are not allowed to provide welfare houses
to employees As a result the fully market-oriented residential houses
contribute the majority of condominium supply in housing market and their
prices also follows similar movements On the other hand we find a contrary
result for economical house price which has a negative impact on mortgage
movements Since the economic houses focus on the market of medium amp
low income households and new migrants the increased price will weaken
the affordability of some potential buyer and vice versa The fallen price is
favored by more potential buyers most of whom need to rely on the
mortgages to finance their house purchasing
H2 Does the process of urbanisation has a positive effect on the mortgage
credits
The results of our estimation also support our second hypothesis Over the
past two decades China has been witnessing rapid urbanisation more and
more new immigrants choose to settle down in cities This massive internal
migration has brought about more potential home buyers and contributed to
11
The impact of housing price on mortgage credits is tested to be 05 for Ireland 062 for Spain and 075 for European Area (Fitzpatrick and McQuinn 2007 CarboValverde and Francisco Rodriguez 2010 Annett 2005)
19
the mortgage credit boom in China This impact of urbanisation is appreciable
which is reflected by the greater correlation coefficients of population than
other variables in our results Another interesting feature is that the change of
urban population has a more significant impact on the economic housing
market Since the purchasing power of new migrants is not as strong as city
natives the economical houses are of more concern to them and are more
sensitive to the change of urban population
In terms of monetary policies we found the interest rate is increasing with the
mortgage loans It tells us that the raising interest rate have little effect on
controlling the credit boom in China By contrast a negative correlation
between banksrsquo mortgage loans and required reserves for condominium and
residential markets is observed However the required reserves can neither
curb the credit boom for High_Grade and economic housing markets It
implies that although bankers were bracing for a slowdown in home loans
raising required reserves is not a good enough reason for them to curb their
loan to the High_Grade and economic houses mortgages which they view as
health asset in their portfolio Then we argue that compared with interest
tool the required reserve ratio is a relative effective instrument in controlling
the mortgage boom
20
CPI is the index of composite consumption goods12Increased CPI implies a
higher living expenditure which undermines the individualrsquos risk taking
intention of long-term mortgage loans And its impact on High_Grade and
economic housing markets is more significant In addition we found another
notable phenomenon is neither the net interest margin nor the loan to deposit
ratio affects the banksrsquo mortgage loans It tells us that the lending behavior of
Chinese commercial banks is more market-oriented rather not risk- or
profit-adjusted
42 House Prices
The determinants of housing price are illustrated in table 4 We can find that
the mortgage loan has a significant impact on the property prices The effect
on condominium and residential prices is positive which implies the
procyclical behavior of credits boom and condominium prices as a general
However the prices of High_Grade and Economical Houses have illustrated an
entirely different response to mortgage credits The economic houses in China
are also referred to as capped-price houses whose price is more
administrative interference rather not fully market-oriented And the market
of High_Grade properties features the high rigidity The movements of these
two special property markets cannot meet the boom of mortgage credits
12
According to the National Statistic Bureau of China property price is not calculated into CPI
21
Although the raising reserve ratio has little effect the interest rate moves
negative to the condominium prices and plays an active role in restraining the
housing prices We do not find significant impact of Housing Stock expected
appreciation rate of housing price and CPI on the movements of housing
prices
5 Conclusion
We use a bank level data set and panel data approach to gain insight in the
factors determining the growth of mortgage lending and housing prices Based
on Two-Stage Least SquaredInstrumental Variable approach the evidence of
relationship between house prices and mortgage credits is found We
document the positive impact of urbanization effect on the growth of
mortgage lending In terms of monetary policy we find negative effects of
required reserves on the change of mortgage credits and the interest rate on
property prices but not vice versa Our findings have important policy
implications and account for the existing monetary policies which are
implemented in China

1 Introduction
Over the past decade both the mortgage market and property sector have
experienced a dynamic change The current financial crisis which starts from
2008 and makes the whole banking industry suffer is largely attributed to the
meltdown of US subprime mortgage market The rapid growth of real house
prices and mortgage debts has been extensively documented across many
countries (Milesand and Pillonca 2008 Wolswijk 2006) Meanwhile China as
one of the largest emerging markets has witnessed soaring property price and
mortgage credit boom in the domestic market (Liang and Cao 2007) Figure 1
and figure 2 illustrate the movements of mortgage loans and property prices
in mainland China respectively In an international context it is a stylized fact
that the amount of bank lending is strong correlated to the property price
Many existing empirical studies highlight a strong correlation between bank
lending and property prices (Hofmann 2003 Gerlach and Peng2005
Fitzpatrick and McQuinn 2007 Davis and Zhu 2010) China is an interesting
example which also experienced mortgage boom and soaring property prices
She provides a representative figure of emerging property market which grows
and develops out of nothing during the past decades At the same time China
also experienced a tremendous reformation in the banking and house
financing sectors In this paper we focus on the relationship between the
outstanding mortgage loans and housing prices In addition we test the real
effects of bankrsquos characteristics and monetary policies
3
The development of Chinese commercial mortgage market began to
accelerate from 1998 in which year Peoplersquos Bank of China authorizes all
domestic commercial banks to issue household mortgage loans From then on
the Chinese government has embarked upon an effort to introduce
market-oriented mechanisms into property financing system eg financial
leverage through commercial banks All these measures have promoted and
contributed to the housing reform in mainland China (Zhang 2000)
Meanwhile commercial banks also recognize the residential mortgage credits
as health asset in their portfolio given the lower default rate of loans to
individual mortgagors than state-owned entrepreneurs (Deng and Fei 2008)
Accordingly the competition is brought about into house financing market
Although the marketised housing mortgage was first introduced in 1998 the
outstanding mortgage loans soared from 51 billion Yuan in 1999 to 6060
billion Yuan at the end of 2010 The mortgage to loan ratio for all financial
institutions increased from 059 in 1999 to 1265 at the end of 2010
During the same period the property prices increase with the volume of
outstanding mortgage loans during the period 1999-2009 except for 2008 in
which year the influence of financial crisis spread to China Except for
commercial mortgage loans from financial institutions Housing Provident
Fund (HPF) is an alternative way which provides the participants lower
interest rate than commercial banks1
1Since the HPF loan is often not sufficient most house buyers prefer to apply to both HPF and commercial
mortgage loansYeung andHowes (2006) reviewedthe role of the HPF infinancing affordable housing development
4
The Chinese mortgage market is featured in two aspects First a uniform and
adjustable mortgage rate is set by the Peoplersquos Bank of China for all
mortgagers2 Once a new mortgage rate is announced it applies to all types
of mortgages including existing ones Second there has been not yet mature
secondary mortgage market Until now only two Mortgage-Backed Securities
(MBS) have been issued in China3 Consequently Chinese mortgage holders
have limited alternative way to invest and then are sensitive to the change of
mortgage rate (Deng et al 2009) That accounts for the high rate of
prepayment in China
The paper is organized as follows Section 2 reviews theoretical and empirical
literature on the relationship between mortgage lending and property price
and highlights the major contributions of my work Section 3 describes the
data methodology and variables employed in the analysis The empirical
results are presented in section 4 Section 5 concludes this paper
2 Literature Review
Various models and empirical frames have been proposed to explain the close
relationship between bank lending movements and property prices which is
also supported by abundant cross-country evidence (Tsatsaronis and Zhu 2004
in China in detail 2 Since 2005 commercial banks can set individual rate which cannot be lower than 90 percent of the rate set by
the Peoplersquos Bank of China 3According to the report by the Peoplersquos Bank of China only China Construction Bank (CCB) are authorized to
issue MBS in the domestic inter-bank Bond Market amounting to yen3018 billion and yen 416 billion respectively

Eacutegert and Mihaljek 2007 Lacoviello and Minetti 2008 Goodhart and Hofmann
2008 Davis and Zhu2010) and the indications of individual countries such as
the USA (Capozza et al 2002) Spain (Gimeno and Martinez-Carrascal 2006)
Ireland (Fitzpatrick and McQuinn 2007) and China (Liang and Cao 2007)
Hofmann (2003) and Basurto et al (2006) suggest a bi-directional causality
between housing prices and bank credits However Goodhart and Hofmann
(2004) Gerlach and Peng(2005) find that the change of property prices have a
significant impact on bank lending without the real effect of bank credits on
property prices By contrast Liang and Cao (2007) investigate the case of China
and suggest a unidirectional causality from bank lending to property prices
which differs from previous empirical work about developed economies
Although the empirical analyses above are attractive and involve standard
ldquobubble bustersrdquo such as income or interest into their frameworks they are
hard to explain the real effects theoretically and rather ad hoc There are two
alternative models in the literature to systematically and theoretically
interpret the housing prices The first one is an inverted demand model which
includes the per capita housing supply and an index of credit conditioning as
additional explanatory variables and then provides better theoretical
foundations (Muellbauer and Murphy 1997 Meen 2002) This model is
appropriate for those countries in which the housing supply rockets up
considerably The alternative model is the house price-to-rent model (Ayuso
and Restoy 2006) It assumes the house rent-to-price ratio only depends on the
6
user costs and investigates the arbitrage between occupied and rental housing
market It is attractive to those countries such as the US in which rent is
market-oriented
Although the previous work using a bank-level data is not much Davis and Zhu
(2009) employ a sample of micro data from 904 banks in 17 countries during
the period 1989-2002 and find strong correlation between bank credits and
commercial property in those countries which experienced crises linked to
property loss by banks To my knowledge there has been no previous research
that investigates the Chinese case using a bank level data Our paper
supplements the existing literature in three ways First a unique bank-level
mortgage data - which consists of a sample of 28 Chinese domestic
commercial banks during the period 2003-2009 - is employed for the empirical
analysis Second we estimate the nexus between the mortgage credits boom
and four different housing prices Finally we include the urbalisation and
monetary policy indices to capture the effects of socio-demographic change
and regulatory constraints respectively
3 Data Description and methodology
31 Methodology
We aim to investigate the interrelation between bank mortgage and property
markets and test two hypotheses below
7
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
H2 Does The process of urbanisation have a positive effect on the mortgage
credits
In addition along with the credit boom the central bank has carried out
different monetary policies to intervene with the property and mortgage
market indirectly We also test the real effect of interest instrument and
required reserve ratio on both housing prices and mortgage lending In order
to test the hypotheses above we first propose the model of banksrsquo and
borrowersrsquo behavior in the context of house financing through mortgage
lending
Borrowerrsquos behavior
Assume there are two goods house occupation and a composite consumption
good We use Cobb-Douglas utility function to analyze borrowerrsquos behavior
1U X Y
Where U denotes the utility of a borrower X is the consumption of composite
good and Y is the house occupation of the household Considering the
monotonicity of utility function we take logarithmic transformation and α is
the indicator of house purchase intension
log log (1 ) logU X Y
Suppose the household use mortgage loan to finance the house occupation
8
and dispensable income to support the consumption of house service and
composite good Then we can get borrowerrsquos maximum utility under the
constraint of dispensable income
max log log (1 ) logX Y U X Y
st [1 ( )]X r i M I
M P Y
Where I represents the dispensable income of borrower r is the real interest
rate of individual banks i denotes the inflation rate M is the total mortgage
loans P is the house price Optimal allocation is solved through Lagrange
function
log (1 ) log [ (1 ) ]L X Y X r i P Y I
Thesis of the Lagrange function is shown as follows
0
1(1 ) 0

Y Y
LX r i P Y I
By solving the linear equation system above with three unknowns which are P
M and λ respectively we get

IM P Y

From the equation of M we argue that Mortgage demand increases with
9
borrowerrsquos income and house price but decreases with house purchase
intension and the interest rate In addition inflation has a positive impact on
mortgage demanding
Bankrsquos behavior
We assume the whole deposits of banks are interest-bearing assets She
allocates a proportion of its total Deposits on mortgage loans The total
mortgage lending is denoted as Y which is equal to consumersrsquo demanding of
mortgage loans The Loan_To_Deposit ratio is θ Then the mortgage can be
rewritten as Y D An individual bank enjoys an interest rate r on its
mortgage loans On the other hand she has to pay out the interest rate dr on
its deposits The lending business of individual bank incurs costs C which is
explained as a quadratic function 2( ) (1 )C Y c Y The individual bank aims to
maximize its total profits which is denoted as Then the maximization
function can be outlined as follows
2max [1 ] dr M N c Y r D
with M N P Y
D M
Then we plug M and D into our target function and get

(N) housing price (P) and decrease with its Loan_To_Deposit ratio (θ)
Econometric approach
Based on the theoretical analysis above we propose an empirical framework
to estimate the movements of mortgage lending as follows
1 1 1Mortgage Pop Interest Rate Inflation NIM LTD House Prices it it it it i t i t it itf RR
The index of potential mortgagers is Pop which is estimated by the
percentage of urban population to total population in China It also refers to
the effect of urbanization and internal migration Inflation and House Prices
are macroeconomic factors which have potential impact on the mortgage
market NIM LTD represents the Net Interest Margins and Loan to Deposit
ratio These variables reflect the characteristics of individual banks Interest
Rate and RR the Required Reserves of banks are proxies of monetary policy
constraints
11
Previous research also indicates that House price is rather an endogenous
variable and driven by market factors including creditmortgage rationing
Inverted demand equation is then widely used to estimate the house prices
We employ a simplified version of the house price model which is proposed by
Muellbauer and Murphy (1997) 4
( )HS Pop f I D
( )eP r P P
Where is the real user cost of housing services P is the real housing price
and eP P is the expected appreciation rate of housing price5 Muellbauer
and Murphy (1997) also pointed out that a proxy for creditmortgage
rationing is often included in the measurement housing price Substituting the
user cost into the housing stock function and involve the proxy of credit
conditions we can get the invert demand function to obtain the estimation of
P
( _ )eP f HS P P I credit rationing
Where HS eP P and I represent the housing stock expected appreciation
rate of housing price and the Income respectively Here in our frame we
employ the ratio of house price to house rental index to proxy the
appreciation rate Although the down payment ratio is a good and popular
index of credit rationing Chinese housing financing system has not
4Dougherty and Order investigate the measurement of the housing cost through two alternative approaches
They deduct the capital cost by maximizing household utility or implicit rent of the landlord and come up with the same results 5 Murphy also pointed that the long-run price-to-rent ratio can be estimated by real user cost and loan-to-value
ratio
12
experienced significant change of this ratio However the change of Mortgage
can partially reflect the bankrsquos credit rationing The increase of mortgage loans
is associated with loose credit rationing and lower interest rate Therefore we
employ the change of mortgage to proxy the credit rationing index Taking
into account the estimation of mortgage lending we form a simultaneous
equation system as follows to estimate mortgage loans and endogenous
housing prices Considering the bank-level mortgage loan data panel data
approach and two-stage least squaresInstrument variable method are
employed in our estimation

32 Data description
Compared with developed countries Chinese mortgage market has a relative
short history and therefore limited data available In this paper an unbalanced
panel of annual mortgage loans of Commercial Banks is employed for the
analysis 6 Our sample consists of all State-Owned-Banks (SOBs)
Joint-Stock-Banks (JSBs) and major City-Commercial-Banks (CCBs) The sum of
mortgage credits in our sample covers more than 80 of total mortgage
outstanding which makes our sample highly representative Therefore fixed
effect model is more appropriate to control for the individual heterogeneity
6Since the financial reform in Chinese banking sector and new enforcement of information disclosure by China
Bank Regulatory Commission the mortgage data for some banks in early years is not available
13
Next we carefully select conventional explanatory variables for our empirical
analysis so as to ensure our estimation is robust to omitted variables The
variables included in the empirical framework are described in groups as
follows The macro data which is collected from the Peoplersquos Bank of China
and National Bureau of Statistics of China Mortgage loans bank specific
variables and house prices are collected from ALMANAC OF CHINAS FINANCE
AND BANKING which is the official publication of Peoplersquos Bank of China
Dependent variables
We are more interested in the movements of mortgage loan and housing
prices within a given year Therefore the change of mortgage loans of
individual banks and housing prices are employed as the dependent variable
In addition log transformation of mortgage loans is employed In order to
avoid heteroscedasticity
Macroeconomic explanatory variables
Although GDP is a popular variable to assess the macroeconomic situation
(Liang and Cao 2007 Davis and Zhu 2010) a large body of literature explores
the impact of disposable income as an alternative McQuinn and OrsquoReilly
(2007) Hill and Gan(2008) established the relationship between income and
house price from both theoretical and empirical sides7 Urban disposable
7Other existing researches also corroborate the potent influence of household income on the dynamics of
housing prices see Jud and Winkler 2002 Gimeno and Martinez-Carrascal 2006 Bourassa and Hoesli2006
14
Income is appropriate to analyse the movement of property prices We
employ the national average deposable income for SOBs and JSBs given their
nationwide business line and local average disposable income for CCBs
considering their local market focus In addition urban disposable income is
log transformed in order to avoid heteroscedasticity problem8
Urbanization is another factor of our interests that may drive the movement of
mortgage credits Over the past decade China has experienced a dramatic
process of industrialisation and urbanisation And Comparing with
industrialisation Chinas urbanisation developed more rapidly (Zheng et al
2007) More and more new immigrants moved into cities Taking into account
more potential home buyers a higher volume of mortgage loans is expected
We use the percentage of urban population to total population to capture the
effect of urbanisation
House stock refers to the number of existing residential units It is also
considered as the response to the land-use regulation through the elasticity of
new housing supply (Quigley and Raphael 2005) In our empirical analysis we
employ the number of house sales to proxy the housing stocks Furthermore
the expected rate of appreciation of house prices reflects consumersrsquo
Nevertheless some other literatures are not in favor of this point of viewGallin (2006) analyzes a panel of 95 US metropolitan areas over 23 years and does not find evidence of long-run relationship between the property prices and income in level This result is also proved by Tsatsaronis and Zhu (2004) who find little impact of household income on housing prices in their cross-country analysis 8No evidence of long-run relationship between the level of property prices and level of income is found by in
Gallin (2006) Therefore we intend to investigate this issue by involving log transformation of income (Ermini and Hendry2008)
15
purchase intention of houses In this empirical framework the ratio of house
price index to rental price index is used to proxy the house prices appreciation
And it is lagged one period to reduce simultaneity
Bank specific explanatory variables
The interest rate as an indicator of monetary policy is another widely
accepted explanatory variable9 It is calculated as the ratio of total interest
revenue over to interest bearing assets of individual banks A declining interest
rate environment contributes to the increasing demand for real estate and
housing investment (Greenand Shoven1986 Kearl1979 Tsatsaronis and Zhu
2004) In terms of Chinese housing market Liang and Cao (2007) suggest that
the property price movements have no sensitivity to the change of the real
interest rate By involving the rate of interest we reinvestigate to what extend
the raising interest rate can affect the mortgage credits and property prices
The required reserves are required to hold by commercial banks in the form of
deposits at the central bank Over the past decade along with the soaring
property prices and mortgage credit boom the central bank has raised the
required reserve ratio several times from 6 in 1999 to 20 in 2011 It is
viewed as another frequently used monetary policy other than the interest
9Hofmann (2003) concludes that real interest rate is more closely associated with property prices than with bank
lendingWolswijk (2006) and Eacutegertand Mihaljek (2007) confirm the negative effect of interest rate on houses prices in 15 EU countries and Eastern Europe
16
rate in China We explore in our paper whether the change of bank required
reserves has an impact on the movements of properties and mortgage credits
And we will compare the real effect of interest rate and required reserve ratio
We use one period lag transformation to reduce simultaneity
Loan_to_asset ratio is an important measure of balance sheet risk of individual
banks Since banks can not grant credit at all costs they need to conduct credit
audit and monitoring effectively in order to maintain low levels of
non-performing loans and increase margins (Abreuand Mendes 2001) In spite
of a positive relationship between Loan to deposit ratio and bank profitability
a high loan to deposit ratio is a warning sign of bankrsquos loan risk and then
discourage credit expansion In order to reduce simultaneity one period
lagged Loan_to_asset ratio is employed to capture the real effect of banksrsquo risk
taking behavior NIM is referred to as the net yield on interest-earning assets
and an indicator of profitability of a bankrsquos lending activities10 In addition
NIM is also a proxy of bank performance and profitability for Chinese banking
sector (Matthews 2009) We would like to test the favor of individual banks on
mortgage profits
Property prices as explanatory variables
The growth of four different property prices is employed in the empirical

Hanweck and Ryu (2005) capture NIM dynamics in response to unanticipated credit and find negative relationship between NIM and expected credit loss

framework They are condominium price the average real estate price and an
indicator of the whole property market residential price the indicator of solo
residential market high_grade houses price a measure of luxury and high-end
real estate market and economic houses price the price of affordable houses
for low-and-medium wage households Crone and Voith(1992) compare five
popular methods to estimate house price appreciation and conclude that the
mean sales price is least affected by the sample size and more accurate than
other estimating methods We aim to investigate the impact of different prices
on the change of mortgage separately The same as disposable income and
mortgage outstanding property prices are converted to logarithm form in
order to avoid heteroscedasticity problem Figure 4 illustrates the movements
of property prices in four separate real estate market
4 Results
41 Mortgage loans
The determinants mortgage lending are illustrated in table 3 from which we
test our hypotheses proposed in section 31
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
Our findings so far suggest that the volume of outstanding mortgage loans
increases with housing prices expect for the economic housing market which
is not surprising and in line with most recent evidence of developed countries
18
However we argue that the elasticity of condominium (and residential) price
to mortgage credits is around 17 which is much higher than that of other
countries 11 The condominium and residential prices illustrate a similar
impact on the mortgage lending It is simply because after the housing
reformation in 1998 all work units are not allowed to provide welfare houses
to employees As a result the fully market-oriented residential houses
contribute the majority of condominium supply in housing market and their
prices also follows similar movements On the other hand we find a contrary
result for economical house price which has a negative impact on mortgage
movements Since the economic houses focus on the market of medium amp
low income households and new migrants the increased price will weaken
the affordability of some potential buyer and vice versa The fallen price is
favored by more potential buyers most of whom need to rely on the
mortgages to finance their house purchasing
H2 Does the process of urbanisation has a positive effect on the mortgage
credits
The results of our estimation also support our second hypothesis Over the
past two decades China has been witnessing rapid urbanisation more and
more new immigrants choose to settle down in cities This massive internal
migration has brought about more potential home buyers and contributed to
11
The impact of housing price on mortgage credits is tested to be 05 for Ireland 062 for Spain and 075 for European Area (Fitzpatrick and McQuinn 2007 CarboValverde and Francisco Rodriguez 2010 Annett 2005)
19
the mortgage credit boom in China This impact of urbanisation is appreciable
which is reflected by the greater correlation coefficients of population than
other variables in our results Another interesting feature is that the change of
urban population has a more significant impact on the economic housing
market Since the purchasing power of new migrants is not as strong as city
natives the economical houses are of more concern to them and are more
sensitive to the change of urban population
In terms of monetary policies we found the interest rate is increasing with the
mortgage loans It tells us that the raising interest rate have little effect on
controlling the credit boom in China By contrast a negative correlation
between banksrsquo mortgage loans and required reserves for condominium and
residential markets is observed However the required reserves can neither
curb the credit boom for High_Grade and economic housing markets It
implies that although bankers were bracing for a slowdown in home loans
raising required reserves is not a good enough reason for them to curb their
loan to the High_Grade and economic houses mortgages which they view as
health asset in their portfolio Then we argue that compared with interest
tool the required reserve ratio is a relative effective instrument in controlling
the mortgage boom
20
CPI is the index of composite consumption goods12Increased CPI implies a
higher living expenditure which undermines the individualrsquos risk taking
intention of long-term mortgage loans And its impact on High_Grade and
economic housing markets is more significant In addition we found another
notable phenomenon is neither the net interest margin nor the loan to deposit
ratio affects the banksrsquo mortgage loans It tells us that the lending behavior of
Chinese commercial banks is more market-oriented rather not risk- or
profit-adjusted
42 House Prices
The determinants of housing price are illustrated in table 4 We can find that
the mortgage loan has a significant impact on the property prices The effect
on condominium and residential prices is positive which implies the
procyclical behavior of credits boom and condominium prices as a general
However the prices of High_Grade and Economical Houses have illustrated an
entirely different response to mortgage credits The economic houses in China
are also referred to as capped-price houses whose price is more
administrative interference rather not fully market-oriented And the market
of High_Grade properties features the high rigidity The movements of these
two special property markets cannot meet the boom of mortgage credits
12
According to the National Statistic Bureau of China property price is not calculated into CPI
21
Although the raising reserve ratio has little effect the interest rate moves
negative to the condominium prices and plays an active role in restraining the
housing prices We do not find significant impact of Housing Stock expected
appreciation rate of housing price and CPI on the movements of housing
prices
5 Conclusion
We use a bank level data set and panel data approach to gain insight in the
factors determining the growth of mortgage lending and housing prices Based
on Two-Stage Least SquaredInstrumental Variable approach the evidence of
relationship between house prices and mortgage credits is found We
document the positive impact of urbanization effect on the growth of
mortgage lending In terms of monetary policy we find negative effects of
required reserves on the change of mortgage credits and the interest rate on
property prices but not vice versa Our findings have important policy
implications and account for the existing monetary policies which are
implemented in China

The development of Chinese commercial mortgage market began to
accelerate from 1998 in which year Peoplersquos Bank of China authorizes all
domestic commercial banks to issue household mortgage loans From then on
the Chinese government has embarked upon an effort to introduce
market-oriented mechanisms into property financing system eg financial
leverage through commercial banks All these measures have promoted and
contributed to the housing reform in mainland China (Zhang 2000)
Meanwhile commercial banks also recognize the residential mortgage credits
as health asset in their portfolio given the lower default rate of loans to
individual mortgagors than state-owned entrepreneurs (Deng and Fei 2008)
Accordingly the competition is brought about into house financing market
Although the marketised housing mortgage was first introduced in 1998 the
outstanding mortgage loans soared from 51 billion Yuan in 1999 to 6060
billion Yuan at the end of 2010 The mortgage to loan ratio for all financial
institutions increased from 059 in 1999 to 1265 at the end of 2010
During the same period the property prices increase with the volume of
outstanding mortgage loans during the period 1999-2009 except for 2008 in
which year the influence of financial crisis spread to China Except for
commercial mortgage loans from financial institutions Housing Provident
Fund (HPF) is an alternative way which provides the participants lower
interest rate than commercial banks1
1Since the HPF loan is often not sufficient most house buyers prefer to apply to both HPF and commercial
mortgage loansYeung andHowes (2006) reviewedthe role of the HPF infinancing affordable housing development
4
The Chinese mortgage market is featured in two aspects First a uniform and
adjustable mortgage rate is set by the Peoplersquos Bank of China for all
mortgagers2 Once a new mortgage rate is announced it applies to all types
of mortgages including existing ones Second there has been not yet mature
secondary mortgage market Until now only two Mortgage-Backed Securities
(MBS) have been issued in China3 Consequently Chinese mortgage holders
have limited alternative way to invest and then are sensitive to the change of
mortgage rate (Deng et al 2009) That accounts for the high rate of
prepayment in China
The paper is organized as follows Section 2 reviews theoretical and empirical
literature on the relationship between mortgage lending and property price
and highlights the major contributions of my work Section 3 describes the
data methodology and variables employed in the analysis The empirical
results are presented in section 4 Section 5 concludes this paper
2 Literature Review
Various models and empirical frames have been proposed to explain the close
relationship between bank lending movements and property prices which is
also supported by abundant cross-country evidence (Tsatsaronis and Zhu 2004
in China in detail 2 Since 2005 commercial banks can set individual rate which cannot be lower than 90 percent of the rate set by
the Peoplersquos Bank of China 3According to the report by the Peoplersquos Bank of China only China Construction Bank (CCB) are authorized to
issue MBS in the domestic inter-bank Bond Market amounting to yen3018 billion and yen 416 billion respectively

2008 Davis and Zhu2010) and the indications of individual countries such as
the USA (Capozza et al 2002) Spain (Gimeno and Martinez-Carrascal 2006)
Ireland (Fitzpatrick and McQuinn 2007) and China (Liang and Cao 2007)
Hofmann (2003) and Basurto et al (2006) suggest a bi-directional causality
between housing prices and bank credits However Goodhart and Hofmann
(2004) Gerlach and Peng(2005) find that the change of property prices have a
significant impact on bank lending without the real effect of bank credits on
property prices By contrast Liang and Cao (2007) investigate the case of China
and suggest a unidirectional causality from bank lending to property prices
which differs from previous empirical work about developed economies
Although the empirical analyses above are attractive and involve standard
ldquobubble bustersrdquo such as income or interest into their frameworks they are
hard to explain the real effects theoretically and rather ad hoc There are two
alternative models in the literature to systematically and theoretically
interpret the housing prices The first one is an inverted demand model which
includes the per capita housing supply and an index of credit conditioning as
additional explanatory variables and then provides better theoretical
foundations (Muellbauer and Murphy 1997 Meen 2002) This model is
appropriate for those countries in which the housing supply rockets up
considerably The alternative model is the house price-to-rent model (Ayuso
and Restoy 2006) It assumes the house rent-to-price ratio only depends on the
6
user costs and investigates the arbitrage between occupied and rental housing
market It is attractive to those countries such as the US in which rent is
market-oriented
Although the previous work using a bank-level data is not much Davis and Zhu
(2009) employ a sample of micro data from 904 banks in 17 countries during
the period 1989-2002 and find strong correlation between bank credits and
commercial property in those countries which experienced crises linked to
property loss by banks To my knowledge there has been no previous research
that investigates the Chinese case using a bank level data Our paper
supplements the existing literature in three ways First a unique bank-level
mortgage data - which consists of a sample of 28 Chinese domestic
commercial banks during the period 2003-2009 - is employed for the empirical
analysis Second we estimate the nexus between the mortgage credits boom
and four different housing prices Finally we include the urbalisation and
monetary policy indices to capture the effects of socio-demographic change
and regulatory constraints respectively
3 Data Description and methodology
31 Methodology
We aim to investigate the interrelation between bank mortgage and property
markets and test two hypotheses below
7
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
H2 Does The process of urbanisation have a positive effect on the mortgage
credits
In addition along with the credit boom the central bank has carried out
different monetary policies to intervene with the property and mortgage
market indirectly We also test the real effect of interest instrument and
required reserve ratio on both housing prices and mortgage lending In order
to test the hypotheses above we first propose the model of banksrsquo and
borrowersrsquo behavior in the context of house financing through mortgage
lending
Borrowerrsquos behavior
Assume there are two goods house occupation and a composite consumption
good We use Cobb-Douglas utility function to analyze borrowerrsquos behavior
1U X Y
Where U denotes the utility of a borrower X is the consumption of composite
good and Y is the house occupation of the household Considering the
monotonicity of utility function we take logarithmic transformation and α is
the indicator of house purchase intension
log log (1 ) logU X Y
Suppose the household use mortgage loan to finance the house occupation
8
and dispensable income to support the consumption of house service and
composite good Then we can get borrowerrsquos maximum utility under the
constraint of dispensable income
max log log (1 ) logX Y U X Y
st [1 ( )]X r i M I
M P Y
Where I represents the dispensable income of borrower r is the real interest
rate of individual banks i denotes the inflation rate M is the total mortgage
loans P is the house price Optimal allocation is solved through Lagrange
function
log (1 ) log [ (1 ) ]L X Y X r i P Y I
Thesis of the Lagrange function is shown as follows
0
1(1 ) 0

LX r i P Y I
By solving the linear equation system above with three unknowns which are P
M and λ respectively we get

(1 )
IM P Y
r i
From the equation of M we argue that Mortgage demand increases with
9
borrowerrsquos income and house price but decreases with house purchase
intension and the interest rate In addition inflation has a positive impact on
mortgage demanding
Bankrsquos behavior
We assume the whole deposits of banks are interest-bearing assets She
allocates a proportion of its total Deposits on mortgage loans The total
mortgage lending is denoted as Y which is equal to consumersrsquo demanding of
mortgage loans The Loan_To_Deposit ratio is θ Then the mortgage can be
rewritten as Y D An individual bank enjoys an interest rate r on its
mortgage loans On the other hand she has to pay out the interest rate dr on
its deposits The lending business of individual bank incurs costs C which is
explained as a quadratic function 2( ) (1 )C Y c Y The individual bank aims to
maximize its total profits which is denoted as Then the maximization
function can be outlined as follows
2max [1 ] dr M N c Y r D
with M N P Y
D M
Then we plug M and D into our target function and get

supply provided by the bank increases with its NIM the number of mortgagers
(N) housing price (P) and decrease with its Loan_To_Deposit ratio (θ)
Econometric approach
Based on the theoretical analysis above we propose an empirical framework
to estimate the movements of mortgage lending as follows
1 1 1Mortgage Pop Interest Rate Inflation NIM LTD House Prices it it it it i t i t it itf RR
The index of potential mortgagers is Pop which is estimated by the
percentage of urban population to total population in China It also refers to
the effect of urbanization and internal migration Inflation and House Prices
are macroeconomic factors which have potential impact on the mortgage
market NIM LTD represents the Net Interest Margins and Loan to Deposit
ratio These variables reflect the characteristics of individual banks Interest
Rate and RR the Required Reserves of banks are proxies of monetary policy
constraints
11
Previous research also indicates that House price is rather an endogenous
variable and driven by market factors including creditmortgage rationing
Inverted demand equation is then widely used to estimate the house prices
We employ a simplified version of the house price model which is proposed by
Muellbauer and Murphy (1997) 4
( )HS Pop f I D
( )eP r P P
Where is the real user cost of housing services P is the real housing price
and eP P is the expected appreciation rate of housing price5 Muellbauer
and Murphy (1997) also pointed out that a proxy for creditmortgage
rationing is often included in the measurement housing price Substituting the
user cost into the housing stock function and involve the proxy of credit
conditions we can get the invert demand function to obtain the estimation of
P
( _ )eP f HS P P I credit rationing
Where HS eP P and I represent the housing stock expected appreciation
rate of housing price and the Income respectively Here in our frame we
employ the ratio of house price to house rental index to proxy the
appreciation rate Although the down payment ratio is a good and popular
index of credit rationing Chinese housing financing system has not
4Dougherty and Order investigate the measurement of the housing cost through two alternative approaches
They deduct the capital cost by maximizing household utility or implicit rent of the landlord and come up with the same results 5 Murphy also pointed that the long-run price-to-rent ratio can be estimated by real user cost and loan-to-value

experienced significant change of this ratio However the change of Mortgage
can partially reflect the bankrsquos credit rationing The increase of mortgage loans
is associated with loose credit rationing and lower interest rate Therefore we
employ the change of mortgage to proxy the credit rationing index Taking
into account the estimation of mortgage lending we form a simultaneous
equation system as follows to estimate mortgage loans and endogenous
housing prices Considering the bank-level mortgage loan data panel data

32 Data description
Compared with developed countries Chinese mortgage market has a relative
short history and therefore limited data available In this paper an unbalanced
panel of annual mortgage loans of Commercial Banks is employed for the
analysis 6 Our sample consists of all State-Owned-Banks (SOBs)
Joint-Stock-Banks (JSBs) and major City-Commercial-Banks (CCBs) The sum of
mortgage credits in our sample covers more than 80 of total mortgage
outstanding which makes our sample highly representative Therefore fixed
effect model is more appropriate to control for the individual heterogeneity
6Since the financial reform in Chinese banking sector and new enforcement of information disclosure by China
Bank Regulatory Commission the mortgage data for some banks in early years is not available
13
Next we carefully select conventional explanatory variables for our empirical
analysis so as to ensure our estimation is robust to omitted variables The
variables included in the empirical framework are described in groups as
follows The macro data which is collected from the Peoplersquos Bank of China
and National Bureau of Statistics of China Mortgage loans bank specific
variables and house prices are collected from ALMANAC OF CHINAS FINANCE
AND BANKING which is the official publication of Peoplersquos Bank of China
Dependent variables
We are more interested in the movements of mortgage loan and housing
prices within a given year Therefore the change of mortgage loans of
individual banks and housing prices are employed as the dependent variable
In addition log transformation of mortgage loans is employed In order to
avoid heteroscedasticity
Macroeconomic explanatory variables
Although GDP is a popular variable to assess the macroeconomic situation
(Liang and Cao 2007 Davis and Zhu 2010) a large body of literature explores
the impact of disposable income as an alternative McQuinn and OrsquoReilly
(2007) Hill and Gan(2008) established the relationship between income and
house price from both theoretical and empirical sides7 Urban disposable
7Other existing researches also corroborate the potent influence of household income on the dynamics of
housing prices see Jud and Winkler 2002 Gimeno and Martinez-Carrascal 2006 Bourassa and Hoesli2006
14
Income is appropriate to analyse the movement of property prices We
employ the national average deposable income for SOBs and JSBs given their
nationwide business line and local average disposable income for CCBs
considering their local market focus In addition urban disposable income is
log transformed in order to avoid heteroscedasticity problem8
Urbanization is another factor of our interests that may drive the movement of
mortgage credits Over the past decade China has experienced a dramatic
process of industrialisation and urbanisation And Comparing with
industrialisation Chinas urbanisation developed more rapidly (Zheng et al
2007) More and more new immigrants moved into cities Taking into account
more potential home buyers a higher volume of mortgage loans is expected
We use the percentage of urban population to total population to capture the
effect of urbanisation
House stock refers to the number of existing residential units It is also
considered as the response to the land-use regulation through the elasticity of
new housing supply (Quigley and Raphael 2005) In our empirical analysis we
employ the number of house sales to proxy the housing stocks Furthermore
the expected rate of appreciation of house prices reflects consumersrsquo
Nevertheless some other literatures are not in favor of this point of viewGallin (2006) analyzes a panel of 95 US metropolitan areas over 23 years and does not find evidence of long-run relationship between the property prices and income in level This result is also proved by Tsatsaronis and Zhu (2004) who find little impact of household income on housing prices in their cross-country analysis 8No evidence of long-run relationship between the level of property prices and level of income is found by in
Gallin (2006) Therefore we intend to investigate this issue by involving log transformation of income (Ermini and Hendry2008)
15
purchase intention of houses In this empirical framework the ratio of house
price index to rental price index is used to proxy the house prices appreciation
And it is lagged one period to reduce simultaneity
Bank specific explanatory variables
The interest rate as an indicator of monetary policy is another widely
accepted explanatory variable9 It is calculated as the ratio of total interest
revenue over to interest bearing assets of individual banks A declining interest
rate environment contributes to the increasing demand for real estate and
housing investment (Greenand Shoven1986 Kearl1979 Tsatsaronis and Zhu
2004) In terms of Chinese housing market Liang and Cao (2007) suggest that
the property price movements have no sensitivity to the change of the real
interest rate By involving the rate of interest we reinvestigate to what extend
the raising interest rate can affect the mortgage credits and property prices
The required reserves are required to hold by commercial banks in the form of
deposits at the central bank Over the past decade along with the soaring
property prices and mortgage credit boom the central bank has raised the
required reserve ratio several times from 6 in 1999 to 20 in 2011 It is
viewed as another frequently used monetary policy other than the interest
9Hofmann (2003) concludes that real interest rate is more closely associated with property prices than with bank
lendingWolswijk (2006) and Eacutegertand Mihaljek (2007) confirm the negative effect of interest rate on houses prices in 15 EU countries and Eastern Europe
16
rate in China We explore in our paper whether the change of bank required
reserves has an impact on the movements of properties and mortgage credits
And we will compare the real effect of interest rate and required reserve ratio
We use one period lag transformation to reduce simultaneity
Loan_to_asset ratio is an important measure of balance sheet risk of individual
banks Since banks can not grant credit at all costs they need to conduct credit
audit and monitoring effectively in order to maintain low levels of
non-performing loans and increase margins (Abreuand Mendes 2001) In spite
of a positive relationship between Loan to deposit ratio and bank profitability
a high loan to deposit ratio is a warning sign of bankrsquos loan risk and then
discourage credit expansion In order to reduce simultaneity one period
lagged Loan_to_asset ratio is employed to capture the real effect of banksrsquo risk
taking behavior NIM is referred to as the net yield on interest-earning assets
and an indicator of profitability of a bankrsquos lending activities10 In addition
NIM is also a proxy of bank performance and profitability for Chinese banking
sector (Matthews 2009) We would like to test the favor of individual banks on
mortgage profits
Property prices as explanatory variables
The growth of four different property prices is employed in the empirical

framework They are condominium price the average real estate price and an
indicator of the whole property market residential price the indicator of solo
residential market high_grade houses price a measure of luxury and high-end
real estate market and economic houses price the price of affordable houses
for low-and-medium wage households Crone and Voith(1992) compare five
popular methods to estimate house price appreciation and conclude that the
mean sales price is least affected by the sample size and more accurate than
other estimating methods We aim to investigate the impact of different prices
on the change of mortgage separately The same as disposable income and
mortgage outstanding property prices are converted to logarithm form in
order to avoid heteroscedasticity problem Figure 4 illustrates the movements
of property prices in four separate real estate market
4 Results
41 Mortgage loans
The determinants mortgage lending are illustrated in table 3 from which we
test our hypotheses proposed in section 31
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
Our findings so far suggest that the volume of outstanding mortgage loans
increases with housing prices expect for the economic housing market which
is not surprising and in line with most recent evidence of developed countries
18
However we argue that the elasticity of condominium (and residential) price
to mortgage credits is around 17 which is much higher than that of other
countries 11 The condominium and residential prices illustrate a similar
impact on the mortgage lending It is simply because after the housing
reformation in 1998 all work units are not allowed to provide welfare houses
to employees As a result the fully market-oriented residential houses
contribute the majority of condominium supply in housing market and their
prices also follows similar movements On the other hand we find a contrary
result for economical house price which has a negative impact on mortgage
movements Since the economic houses focus on the market of medium amp
low income households and new migrants the increased price will weaken
the affordability of some potential buyer and vice versa The fallen price is
favored by more potential buyers most of whom need to rely on the
mortgages to finance their house purchasing
H2 Does the process of urbanisation has a positive effect on the mortgage
credits
The results of our estimation also support our second hypothesis Over the
past two decades China has been witnessing rapid urbanisation more and
more new immigrants choose to settle down in cities This massive internal
migration has brought about more potential home buyers and contributed to
11
The impact of housing price on mortgage credits is tested to be 05 for Ireland 062 for Spain and 075 for European Area (Fitzpatrick and McQuinn 2007 CarboValverde and Francisco Rodriguez 2010 Annett 2005)
19
the mortgage credit boom in China This impact of urbanisation is appreciable
which is reflected by the greater correlation coefficients of population than
other variables in our results Another interesting feature is that the change of
urban population has a more significant impact on the economic housing
market Since the purchasing power of new migrants is not as strong as city
natives the economical houses are of more concern to them and are more
sensitive to the change of urban population
In terms of monetary policies we found the interest rate is increasing with the
mortgage loans It tells us that the raising interest rate have little effect on
controlling the credit boom in China By contrast a negative correlation
between banksrsquo mortgage loans and required reserves for condominium and
residential markets is observed However the required reserves can neither
curb the credit boom for High_Grade and economic housing markets It
implies that although bankers were bracing for a slowdown in home loans
raising required reserves is not a good enough reason for them to curb their
loan to the High_Grade and economic houses mortgages which they view as
health asset in their portfolio Then we argue that compared with interest
tool the required reserve ratio is a relative effective instrument in controlling
the mortgage boom
20
CPI is the index of composite consumption goods12Increased CPI implies a
higher living expenditure which undermines the individualrsquos risk taking
intention of long-term mortgage loans And its impact on High_Grade and
economic housing markets is more significant In addition we found another
notable phenomenon is neither the net interest margin nor the loan to deposit
ratio affects the banksrsquo mortgage loans It tells us that the lending behavior of
Chinese commercial banks is more market-oriented rather not risk- or
profit-adjusted
42 House Prices
The determinants of housing price are illustrated in table 4 We can find that
the mortgage loan has a significant impact on the property prices The effect
on condominium and residential prices is positive which implies the
procyclical behavior of credits boom and condominium prices as a general
However the prices of High_Grade and Economical Houses have illustrated an
entirely different response to mortgage credits The economic houses in China
are also referred to as capped-price houses whose price is more
administrative interference rather not fully market-oriented And the market
of High_Grade properties features the high rigidity The movements of these
two special property markets cannot meet the boom of mortgage credits
12
According to the National Statistic Bureau of China property price is not calculated into CPI
21
Although the raising reserve ratio has little effect the interest rate moves
negative to the condominium prices and plays an active role in restraining the
housing prices We do not find significant impact of Housing Stock expected
appreciation rate of housing price and CPI on the movements of housing
prices
5 Conclusion
We use a bank level data set and panel data approach to gain insight in the
factors determining the growth of mortgage lending and housing prices Based
on Two-Stage Least SquaredInstrumental Variable approach the evidence of
relationship between house prices and mortgage credits is found We
document the positive impact of urbanization effect on the growth of
mortgage lending In terms of monetary policy we find negative effects of
required reserves on the change of mortgage credits and the interest rate on
property prices but not vice versa Our findings have important policy
implications and account for the existing monetary policies which are
implemented in China

The Chinese mortgage market is featured in two aspects First a uniform and
adjustable mortgage rate is set by the Peoplersquos Bank of China for all
mortgagers2 Once a new mortgage rate is announced it applies to all types
of mortgages including existing ones Second there has been not yet mature
secondary mortgage market Until now only two Mortgage-Backed Securities
(MBS) have been issued in China3 Consequently Chinese mortgage holders
have limited alternative way to invest and then are sensitive to the change of
mortgage rate (Deng et al 2009) That accounts for the high rate of
prepayment in China
The paper is organized as follows Section 2 reviews theoretical and empirical
literature on the relationship between mortgage lending and property price
and highlights the major contributions of my work Section 3 describes the
data methodology and variables employed in the analysis The empirical
results are presented in section 4 Section 5 concludes this paper
2 Literature Review
Various models and empirical frames have been proposed to explain the close
relationship between bank lending movements and property prices which is
also supported by abundant cross-country evidence (Tsatsaronis and Zhu 2004
in China in detail 2 Since 2005 commercial banks can set individual rate which cannot be lower than 90 percent of the rate set by
the Peoplersquos Bank of China 3According to the report by the Peoplersquos Bank of China only China Construction Bank (CCB) are authorized to
issue MBS in the domestic inter-bank Bond Market amounting to yen3018 billion and yen 416 billion respectively

Eacutegert and Mihaljek 2007 Lacoviello and Minetti 2008 Goodhart and Hofmann
2008 Davis and Zhu2010) and the indications of individual countries such as
the USA (Capozza et al 2002) Spain (Gimeno and Martinez-Carrascal 2006)
Ireland (Fitzpatrick and McQuinn 2007) and China (Liang and Cao 2007)
Hofmann (2003) and Basurto et al (2006) suggest a bi-directional causality
between housing prices and bank credits However Goodhart and Hofmann
(2004) Gerlach and Peng(2005) find that the change of property prices have a
significant impact on bank lending without the real effect of bank credits on
property prices By contrast Liang and Cao (2007) investigate the case of China
and suggest a unidirectional causality from bank lending to property prices
which differs from previous empirical work about developed economies
Although the empirical analyses above are attractive and involve standard
ldquobubble bustersrdquo such as income or interest into their frameworks they are
hard to explain the real effects theoretically and rather ad hoc There are two
alternative models in the literature to systematically and theoretically
interpret the housing prices The first one is an inverted demand model which
includes the per capita housing supply and an index of credit conditioning as
additional explanatory variables and then provides better theoretical
foundations (Muellbauer and Murphy 1997 Meen 2002) This model is
appropriate for those countries in which the housing supply rockets up
considerably The alternative model is the house price-to-rent model (Ayuso
and Restoy 2006) It assumes the house rent-to-price ratio only depends on the
6
user costs and investigates the arbitrage between occupied and rental housing
market It is attractive to those countries such as the US in which rent is
market-oriented
Although the previous work using a bank-level data is not much Davis and Zhu
(2009) employ a sample of micro data from 904 banks in 17 countries during
the period 1989-2002 and find strong correlation between bank credits and
commercial property in those countries which experienced crises linked to
property loss by banks To my knowledge there has been no previous research
that investigates the Chinese case using a bank level data Our paper
supplements the existing literature in three ways First a unique bank-level
mortgage data - which consists of a sample of 28 Chinese domestic
commercial banks during the period 2003-2009 - is employed for the empirical
analysis Second we estimate the nexus between the mortgage credits boom
and four different housing prices Finally we include the urbalisation and
monetary policy indices to capture the effects of socio-demographic change
and regulatory constraints respectively
3 Data Description and methodology
31 Methodology
We aim to investigate the interrelation between bank mortgage and property
markets and test two hypotheses below
7
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
H2 Does The process of urbanisation have a positive effect on the mortgage
credits
In addition along with the credit boom the central bank has carried out
different monetary policies to intervene with the property and mortgage
market indirectly We also test the real effect of interest instrument and
required reserve ratio on both housing prices and mortgage lending In order
to test the hypotheses above we first propose the model of banksrsquo and
borrowersrsquo behavior in the context of house financing through mortgage
lending
Borrowerrsquos behavior
Assume there are two goods house occupation and a composite consumption
good We use Cobb-Douglas utility function to analyze borrowerrsquos behavior
1U X Y
Where U denotes the utility of a borrower X is the consumption of composite
good and Y is the house occupation of the household Considering the
monotonicity of utility function we take logarithmic transformation and α is
the indicator of house purchase intension
log log (1 ) logU X Y
Suppose the household use mortgage loan to finance the house occupation
8
and dispensable income to support the consumption of house service and
composite good Then we can get borrowerrsquos maximum utility under the
constraint of dispensable income
max log log (1 ) logX Y U X Y
st [1 ( )]X r i M I
M P Y
Where I represents the dispensable income of borrower r is the real interest
rate of individual banks i denotes the inflation rate M is the total mortgage
loans P is the house price Optimal allocation is solved through Lagrange
function
log (1 ) log [ (1 ) ]L X Y X r i P Y I
Thesis of the Lagrange function is shown as follows
0
1(1 ) 0
(1 ) 0

Lr i P
Y Y
LX r i P Y I
By solving the linear equation system above with three unknowns which are P
M and λ respectively we get

(1 )
IM P Y
r i
From the equation of M we argue that Mortgage demand increases with
9
borrowerrsquos income and house price but decreases with house purchase
intension and the interest rate In addition inflation has a positive impact on
mortgage demanding
Bankrsquos behavior
We assume the whole deposits of banks are interest-bearing assets She
allocates a proportion of its total Deposits on mortgage loans The total
mortgage lending is denoted as Y which is equal to consumersrsquo demanding of
mortgage loans The Loan_To_Deposit ratio is θ Then the mortgage can be
rewritten as Y D An individual bank enjoys an interest rate r on its
mortgage loans On the other hand she has to pay out the interest rate dr on
its deposits The lending business of individual bank incurs costs C which is
explained as a quadratic function 2( ) (1 )C Y c Y The individual bank aims to
maximize its total profits which is denoted as Then the maximization
function can be outlined as follows
2max [1 ] dr M N c Y r D
with M N P Y
D M
Then we plug M and D into our target function and get

individual bank and the denominator 2 2cM D c The optimal mortgage
supply provided by the bank increases with its NIM the number of mortgagers
(N) housing price (P) and decrease with its Loan_To_Deposit ratio (θ)
Econometric approach
Based on the theoretical analysis above we propose an empirical framework
to estimate the movements of mortgage lending as follows
1 1 1Mortgage Pop Interest Rate Inflation NIM LTD House Prices it it it it i t i t it itf RR
The index of potential mortgagers is Pop which is estimated by the
percentage of urban population to total population in China It also refers to
the effect of urbanization and internal migration Inflation and House Prices
are macroeconomic factors which have potential impact on the mortgage
market NIM LTD represents the Net Interest Margins and Loan to Deposit
ratio These variables reflect the characteristics of individual banks Interest
Rate and RR the Required Reserves of banks are proxies of monetary policy
constraints
11
Previous research also indicates that House price is rather an endogenous
variable and driven by market factors including creditmortgage rationing
Inverted demand equation is then widely used to estimate the house prices
We employ a simplified version of the house price model which is proposed by
Muellbauer and Murphy (1997) 4
( )HS Pop f I D
( )eP r P P
Where is the real user cost of housing services P is the real housing price
and eP P is the expected appreciation rate of housing price5 Muellbauer
and Murphy (1997) also pointed out that a proxy for creditmortgage
rationing is often included in the measurement housing price Substituting the
user cost into the housing stock function and involve the proxy of credit
conditions we can get the invert demand function to obtain the estimation of
P
( _ )eP f HS P P I credit rationing
Where HS eP P and I represent the housing stock expected appreciation
rate of housing price and the Income respectively Here in our frame we
employ the ratio of house price to house rental index to proxy the
appreciation rate Although the down payment ratio is a good and popular
index of credit rationing Chinese housing financing system has not
4Dougherty and Order investigate the measurement of the housing cost through two alternative approaches
They deduct the capital cost by maximizing household utility or implicit rent of the landlord and come up with the same results 5 Murphy also pointed that the long-run price-to-rent ratio can be estimated by real user cost and loan-to-value
ratio
12
experienced significant change of this ratio However the change of Mortgage
can partially reflect the bankrsquos credit rationing The increase of mortgage loans
is associated with loose credit rationing and lower interest rate Therefore we
employ the change of mortgage to proxy the credit rationing index Taking
into account the estimation of mortgage lending we form a simultaneous
equation system as follows to estimate mortgage loans and endogenous
housing prices Considering the bank-level mortgage loan data panel data
approach and two-stage least squaresInstrument variable method are
employed in our estimation

32 Data description
Compared with developed countries Chinese mortgage market has a relative
short history and therefore limited data available In this paper an unbalanced
panel of annual mortgage loans of Commercial Banks is employed for the
analysis 6 Our sample consists of all State-Owned-Banks (SOBs)
Joint-Stock-Banks (JSBs) and major City-Commercial-Banks (CCBs) The sum of
mortgage credits in our sample covers more than 80 of total mortgage
outstanding which makes our sample highly representative Therefore fixed
effect model is more appropriate to control for the individual heterogeneity
6Since the financial reform in Chinese banking sector and new enforcement of information disclosure by China
Bank Regulatory Commission the mortgage data for some banks in early years is not available
13
Next we carefully select conventional explanatory variables for our empirical
analysis so as to ensure our estimation is robust to omitted variables The
variables included in the empirical framework are described in groups as
follows The macro data which is collected from the Peoplersquos Bank of China
and National Bureau of Statistics of China Mortgage loans bank specific
variables and house prices are collected from ALMANAC OF CHINAS FINANCE
AND BANKING which is the official publication of Peoplersquos Bank of China
Dependent variables
We are more interested in the movements of mortgage loan and housing
prices within a given year Therefore the change of mortgage loans of
individual banks and housing prices are employed as the dependent variable
In addition log transformation of mortgage loans is employed In order to
avoid heteroscedasticity
Macroeconomic explanatory variables
Although GDP is a popular variable to assess the macroeconomic situation
(Liang and Cao 2007 Davis and Zhu 2010) a large body of literature explores
the impact of disposable income as an alternative McQuinn and OrsquoReilly
(2007) Hill and Gan(2008) established the relationship between income and
house price from both theoretical and empirical sides7 Urban disposable
7Other existing researches also corroborate the potent influence of household income on the dynamics of
housing prices see Jud and Winkler 2002 Gimeno and Martinez-Carrascal 2006 Bourassa and Hoesli2006
14
Income is appropriate to analyse the movement of property prices We
employ the national average deposable income for SOBs and JSBs given their
nationwide business line and local average disposable income for CCBs
considering their local market focus In addition urban disposable income is
log transformed in order to avoid heteroscedasticity problem8
Urbanization is another factor of our interests that may drive the movement of
mortgage credits Over the past decade China has experienced a dramatic
process of industrialisation and urbanisation And Comparing with
industrialisation Chinas urbanisation developed more rapidly (Zheng et al
2007) More and more new immigrants moved into cities Taking into account
more potential home buyers a higher volume of mortgage loans is expected
We use the percentage of urban population to total population to capture the
effect of urbanisation
House stock refers to the number of existing residential units It is also
considered as the response to the land-use regulation through the elasticity of
new housing supply (Quigley and Raphael 2005) In our empirical analysis we
employ the number of house sales to proxy the housing stocks Furthermore
the expected rate of appreciation of house prices reflects consumersrsquo
Nevertheless some other literatures are not in favor of this point of viewGallin (2006) analyzes a panel of 95 US metropolitan areas over 23 years and does not find evidence of long-run relationship between the property prices and income in level This result is also proved by Tsatsaronis and Zhu (2004) who find little impact of household income on housing prices in their cross-country analysis 8No evidence of long-run relationship between the level of property prices and level of income is found by in
Gallin (2006) Therefore we intend to investigate this issue by involving log transformation of income (Ermini and Hendry2008)
15
purchase intention of houses In this empirical framework the ratio of house
price index to rental price index is used to proxy the house prices appreciation
And it is lagged one period to reduce simultaneity
Bank specific explanatory variables
The interest rate as an indicator of monetary policy is another widely
accepted explanatory variable9 It is calculated as the ratio of total interest
revenue over to interest bearing assets of individual banks A declining interest
rate environment contributes to the increasing demand for real estate and
housing investment (Greenand Shoven1986 Kearl1979 Tsatsaronis and Zhu
2004) In terms of Chinese housing market Liang and Cao (2007) suggest that
the property price movements have no sensitivity to the change of the real
interest rate By involving the rate of interest we reinvestigate to what extend
the raising interest rate can affect the mortgage credits and property prices
The required reserves are required to hold by commercial banks in the form of
deposits at the central bank Over the past decade along with the soaring
property prices and mortgage credit boom the central bank has raised the
required reserve ratio several times from 6 in 1999 to 20 in 2011 It is
viewed as another frequently used monetary policy other than the interest
9Hofmann (2003) concludes that real interest rate is more closely associated with property prices than with bank
lendingWolswijk (2006) and Eacutegertand Mihaljek (2007) confirm the negative effect of interest rate on houses prices in 15 EU countries and Eastern Europe
16
rate in China We explore in our paper whether the change of bank required
reserves has an impact on the movements of properties and mortgage credits
And we will compare the real effect of interest rate and required reserve ratio
We use one period lag transformation to reduce simultaneity
Loan_to_asset ratio is an important measure of balance sheet risk of individual
banks Since banks can not grant credit at all costs they need to conduct credit
audit and monitoring effectively in order to maintain low levels of
non-performing loans and increase margins (Abreuand Mendes 2001) In spite
of a positive relationship between Loan to deposit ratio and bank profitability
a high loan to deposit ratio is a warning sign of bankrsquos loan risk and then
discourage credit expansion In order to reduce simultaneity one period
lagged Loan_to_asset ratio is employed to capture the real effect of banksrsquo risk
taking behavior NIM is referred to as the net yield on interest-earning assets
and an indicator of profitability of a bankrsquos lending activities10 In addition
NIM is also a proxy of bank performance and profitability for Chinese banking
sector (Matthews 2009) We would like to test the favor of individual banks on
mortgage profits
Property prices as explanatory variables
The growth of four different property prices is employed in the empirical

Hanweck and Ryu (2005) capture NIM dynamics in response to unanticipated credit and find negative relationship between NIM and expected credit loss

framework They are condominium price the average real estate price and an
indicator of the whole property market residential price the indicator of solo
residential market high_grade houses price a measure of luxury and high-end
real estate market and economic houses price the price of affordable houses
for low-and-medium wage households Crone and Voith(1992) compare five
popular methods to estimate house price appreciation and conclude that the
mean sales price is least affected by the sample size and more accurate than
other estimating methods We aim to investigate the impact of different prices
on the change of mortgage separately The same as disposable income and
mortgage outstanding property prices are converted to logarithm form in
order to avoid heteroscedasticity problem Figure 4 illustrates the movements
of property prices in four separate real estate market
4 Results
41 Mortgage loans
The determinants mortgage lending are illustrated in table 3 from which we
test our hypotheses proposed in section 31
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
Our findings so far suggest that the volume of outstanding mortgage loans
increases with housing prices expect for the economic housing market which
is not surprising and in line with most recent evidence of developed countries
18
However we argue that the elasticity of condominium (and residential) price
to mortgage credits is around 17 which is much higher than that of other
countries 11 The condominium and residential prices illustrate a similar
impact on the mortgage lending It is simply because after the housing
reformation in 1998 all work units are not allowed to provide welfare houses
to employees As a result the fully market-oriented residential houses
contribute the majority of condominium supply in housing market and their
prices also follows similar movements On the other hand we find a contrary
result for economical house price which has a negative impact on mortgage
movements Since the economic houses focus on the market of medium amp
low income households and new migrants the increased price will weaken
the affordability of some potential buyer and vice versa The fallen price is
favored by more potential buyers most of whom need to rely on the
mortgages to finance their house purchasing
H2 Does the process of urbanisation has a positive effect on the mortgage
credits
The results of our estimation also support our second hypothesis Over the
past two decades China has been witnessing rapid urbanisation more and
more new immigrants choose to settle down in cities This massive internal
migration has brought about more potential home buyers and contributed to
11
The impact of housing price on mortgage credits is tested to be 05 for Ireland 062 for Spain and 075 for European Area (Fitzpatrick and McQuinn 2007 CarboValverde and Francisco Rodriguez 2010 Annett 2005)
19
the mortgage credit boom in China This impact of urbanisation is appreciable
which is reflected by the greater correlation coefficients of population than
other variables in our results Another interesting feature is that the change of
urban population has a more significant impact on the economic housing
market Since the purchasing power of new migrants is not as strong as city
natives the economical houses are of more concern to them and are more
sensitive to the change of urban population
In terms of monetary policies we found the interest rate is increasing with the
mortgage loans It tells us that the raising interest rate have little effect on
controlling the credit boom in China By contrast a negative correlation
between banksrsquo mortgage loans and required reserves for condominium and
residential markets is observed However the required reserves can neither
curb the credit boom for High_Grade and economic housing markets It
implies that although bankers were bracing for a slowdown in home loans
raising required reserves is not a good enough reason for them to curb their
loan to the High_Grade and economic houses mortgages which they view as
health asset in their portfolio Then we argue that compared with interest
tool the required reserve ratio is a relative effective instrument in controlling
the mortgage boom
20
CPI is the index of composite consumption goods12Increased CPI implies a
higher living expenditure which undermines the individualrsquos risk taking
intention of long-term mortgage loans And its impact on High_Grade and
economic housing markets is more significant In addition we found another
notable phenomenon is neither the net interest margin nor the loan to deposit
ratio affects the banksrsquo mortgage loans It tells us that the lending behavior of
Chinese commercial banks is more market-oriented rather not risk- or
profit-adjusted
42 House Prices
The determinants of housing price are illustrated in table 4 We can find that
the mortgage loan has a significant impact on the property prices The effect
on condominium and residential prices is positive which implies the
procyclical behavior of credits boom and condominium prices as a general
However the prices of High_Grade and Economical Houses have illustrated an
entirely different response to mortgage credits The economic houses in China
are also referred to as capped-price houses whose price is more
administrative interference rather not fully market-oriented And the market
of High_Grade properties features the high rigidity The movements of these
two special property markets cannot meet the boom of mortgage credits
12
According to the National Statistic Bureau of China property price is not calculated into CPI
21
Although the raising reserve ratio has little effect the interest rate moves
negative to the condominium prices and plays an active role in restraining the
housing prices We do not find significant impact of Housing Stock expected
appreciation rate of housing price and CPI on the movements of housing
prices
5 Conclusion
We use a bank level data set and panel data approach to gain insight in the
factors determining the growth of mortgage lending and housing prices Based
on Two-Stage Least SquaredInstrumental Variable approach the evidence of
relationship between house prices and mortgage credits is found We
document the positive impact of urbanization effect on the growth of
mortgage lending In terms of monetary policy we find negative effects of
required reserves on the change of mortgage credits and the interest rate on
property prices but not vice versa Our findings have important policy
implications and account for the existing monetary policies which are
implemented in China

2008 Davis and Zhu2010) and the indications of individual countries such as
the USA (Capozza et al 2002) Spain (Gimeno and Martinez-Carrascal 2006)
Ireland (Fitzpatrick and McQuinn 2007) and China (Liang and Cao 2007)
Hofmann (2003) and Basurto et al (2006) suggest a bi-directional causality
between housing prices and bank credits However Goodhart and Hofmann
(2004) Gerlach and Peng(2005) find that the change of property prices have a
significant impact on bank lending without the real effect of bank credits on
property prices By contrast Liang and Cao (2007) investigate the case of China
and suggest a unidirectional causality from bank lending to property prices
which differs from previous empirical work about developed economies
Although the empirical analyses above are attractive and involve standard
ldquobubble bustersrdquo such as income or interest into their frameworks they are
hard to explain the real effects theoretically and rather ad hoc There are two
alternative models in the literature to systematically and theoretically
interpret the housing prices The first one is an inverted demand model which
includes the per capita housing supply and an index of credit conditioning as
additional explanatory variables and then provides better theoretical
foundations (Muellbauer and Murphy 1997 Meen 2002) This model is
appropriate for those countries in which the housing supply rockets up
considerably The alternative model is the house price-to-rent model (Ayuso
and Restoy 2006) It assumes the house rent-to-price ratio only depends on the
6
user costs and investigates the arbitrage between occupied and rental housing
market It is attractive to those countries such as the US in which rent is
market-oriented
Although the previous work using a bank-level data is not much Davis and Zhu
(2009) employ a sample of micro data from 904 banks in 17 countries during
the period 1989-2002 and find strong correlation between bank credits and
commercial property in those countries which experienced crises linked to
property loss by banks To my knowledge there has been no previous research
that investigates the Chinese case using a bank level data Our paper
supplements the existing literature in three ways First a unique bank-level
mortgage data - which consists of a sample of 28 Chinese domestic
commercial banks during the period 2003-2009 - is employed for the empirical
analysis Second we estimate the nexus between the mortgage credits boom
and four different housing prices Finally we include the urbalisation and
monetary policy indices to capture the effects of socio-demographic change
and regulatory constraints respectively
3 Data Description and methodology
31 Methodology
We aim to investigate the interrelation between bank mortgage and property
markets and test two hypotheses below
7
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
H2 Does The process of urbanisation have a positive effect on the mortgage
credits
In addition along with the credit boom the central bank has carried out
different monetary policies to intervene with the property and mortgage
market indirectly We also test the real effect of interest instrument and
required reserve ratio on both housing prices and mortgage lending In order
to test the hypotheses above we first propose the model of banksrsquo and
borrowersrsquo behavior in the context of house financing through mortgage
lending
Borrowerrsquos behavior
Assume there are two goods house occupation and a composite consumption
good We use Cobb-Douglas utility function to analyze borrowerrsquos behavior
1U X Y
Where U denotes the utility of a borrower X is the consumption of composite
good and Y is the house occupation of the household Considering the
monotonicity of utility function we take logarithmic transformation and α is
the indicator of house purchase intension
log log (1 ) logU X Y
Suppose the household use mortgage loan to finance the house occupation
8
and dispensable income to support the consumption of house service and
composite good Then we can get borrowerrsquos maximum utility under the
constraint of dispensable income
max log log (1 ) logX Y U X Y
st [1 ( )]X r i M I
M P Y
Where I represents the dispensable income of borrower r is the real interest
rate of individual banks i denotes the inflation rate M is the total mortgage
loans P is the house price Optimal allocation is solved through Lagrange
function
log (1 ) log [ (1 ) ]L X Y X r i P Y I
Thesis of the Lagrange function is shown as follows
0
1(1 ) 0
(1 ) 0
L
X X
Lr i P
Y Y
LX r i P Y I
By solving the linear equation system above with three unknowns which are P
M and λ respectively we get
(1 )
(1 )
IM P Y
r i
From the equation of M we argue that Mortgage demand increases with
9
borrowerrsquos income and house price but decreases with house purchase
intension and the interest rate In addition inflation has a positive impact on
mortgage demanding
Bankrsquos behavior
We assume the whole deposits of banks are interest-bearing assets She
allocates a proportion of its total Deposits on mortgage loans The total
mortgage lending is denoted as Y which is equal to consumersrsquo demanding of
mortgage loans The Loan_To_Deposit ratio is θ Then the mortgage can be
rewritten as Y D An individual bank enjoys an interest rate r on its
mortgage loans On the other hand she has to pay out the interest rate dr on
its deposits The lending business of individual bank incurs costs C which is
explained as a quadratic function 2( ) (1 )C Y c Y The individual bank aims to
maximize its total profits which is denoted as Then the maximization
function can be outlined as follows
2max [1 ] dr M N c Y r D
with M N P Y
D M
Then we plug M and D into our target function and get
2max [1 ( ) ] d

Now we can find that

individual bank and the denominator 2 2cM D c The optimal mortgage
supply provided by the bank increases with its NIM the number of mortgagers
(N) housing price (P) and decrease with its Loan_To_Deposit ratio (θ)
Econometric approach
Based on the theoretical analysis above we propose an empirical framework
to estimate the movements of mortgage lending as follows
1 1 1Mortgage Pop Interest Rate Inflation NIM LTD House Prices it it it it i t i t it itf RR
The index of potential mortgagers is Pop which is estimated by the
percentage of urban population to total population in China It also refers to
the effect of urbanization and internal migration Inflation and House Prices
are macroeconomic factors which have potential impact on the mortgage
market NIM LTD represents the Net Interest Margins and Loan to Deposit
ratio These variables reflect the characteristics of individual banks Interest
Rate and RR the Required Reserves of banks are proxies of monetary policy
constraints
11
Previous research also indicates that House price is rather an endogenous
variable and driven by market factors including creditmortgage rationing
Inverted demand equation is then widely used to estimate the house prices
We employ a simplified version of the house price model which is proposed by
Muellbauer and Murphy (1997) 4
( )HS Pop f I D
( )eP r P P
Where is the real user cost of housing services P is the real housing price
and eP P is the expected appreciation rate of housing price5 Muellbauer
and Murphy (1997) also pointed out that a proxy for creditmortgage
rationing is often included in the measurement housing price Substituting the
user cost into the housing stock function and involve the proxy of credit
conditions we can get the invert demand function to obtain the estimation of
P
( _ )eP f HS P P I credit rationing
Where HS eP P and I represent the housing stock expected appreciation
rate of housing price and the Income respectively Here in our frame we
employ the ratio of house price to house rental index to proxy the
appreciation rate Although the down payment ratio is a good and popular
index of credit rationing Chinese housing financing system has not
4Dougherty and Order investigate the measurement of the housing cost through two alternative approaches
They deduct the capital cost by maximizing household utility or implicit rent of the landlord and come up with the same results 5 Murphy also pointed that the long-run price-to-rent ratio can be estimated by real user cost and loan-to-value
ratio
12
experienced significant change of this ratio However the change of Mortgage
can partially reflect the bankrsquos credit rationing The increase of mortgage loans
is associated with loose credit rationing and lower interest rate Therefore we
employ the change of mortgage to proxy the credit rationing index Taking
into account the estimation of mortgage lending we form a simultaneous
equation system as follows to estimate mortgage loans and endogenous
housing prices Considering the bank-level mortgage loan data panel data
approach and two-stage least squaresInstrument variable method are
employed in our estimation

32 Data description
Compared with developed countries Chinese mortgage market has a relative
short history and therefore limited data available In this paper an unbalanced
panel of annual mortgage loans of Commercial Banks is employed for the
analysis 6 Our sample consists of all State-Owned-Banks (SOBs)
Joint-Stock-Banks (JSBs) and major City-Commercial-Banks (CCBs) The sum of
mortgage credits in our sample covers more than 80 of total mortgage
outstanding which makes our sample highly representative Therefore fixed
effect model is more appropriate to control for the individual heterogeneity
6Since the financial reform in Chinese banking sector and new enforcement of information disclosure by China
Bank Regulatory Commission the mortgage data for some banks in early years is not available
13
Next we carefully select conventional explanatory variables for our empirical
analysis so as to ensure our estimation is robust to omitted variables The
variables included in the empirical framework are described in groups as
follows The macro data which is collected from the Peoplersquos Bank of China
and National Bureau of Statistics of China Mortgage loans bank specific
variables and house prices are collected from ALMANAC OF CHINAS FINANCE
AND BANKING which is the official publication of Peoplersquos Bank of China
Dependent variables
We are more interested in the movements of mortgage loan and housing
prices within a given year Therefore the change of mortgage loans of
individual banks and housing prices are employed as the dependent variable
In addition log transformation of mortgage loans is employed In order to
avoid heteroscedasticity
Macroeconomic explanatory variables
Although GDP is a popular variable to assess the macroeconomic situation
(Liang and Cao 2007 Davis and Zhu 2010) a large body of literature explores
the impact of disposable income as an alternative McQuinn and OrsquoReilly
(2007) Hill and Gan(2008) established the relationship between income and
house price from both theoretical and empirical sides7 Urban disposable
7Other existing researches also corroborate the potent influence of household income on the dynamics of
housing prices see Jud and Winkler 2002 Gimeno and Martinez-Carrascal 2006 Bourassa and Hoesli2006
14
Income is appropriate to analyse the movement of property prices We
employ the national average deposable income for SOBs and JSBs given their
nationwide business line and local average disposable income for CCBs
considering their local market focus In addition urban disposable income is
log transformed in order to avoid heteroscedasticity problem8
Urbanization is another factor of our interests that may drive the movement of
mortgage credits Over the past decade China has experienced a dramatic
process of industrialisation and urbanisation And Comparing with
industrialisation Chinas urbanisation developed more rapidly (Zheng et al
2007) More and more new immigrants moved into cities Taking into account
more potential home buyers a higher volume of mortgage loans is expected
We use the percentage of urban population to total population to capture the
effect of urbanisation
House stock refers to the number of existing residential units It is also
considered as the response to the land-use regulation through the elasticity of
new housing supply (Quigley and Raphael 2005) In our empirical analysis we
employ the number of house sales to proxy the housing stocks Furthermore
the expected rate of appreciation of house prices reflects consumersrsquo
Nevertheless some other literatures are not in favor of this point of viewGallin (2006) analyzes a panel of 95 US metropolitan areas over 23 years and does not find evidence of long-run relationship between the property prices and income in level This result is also proved by Tsatsaronis and Zhu (2004) who find little impact of household income on housing prices in their cross-country analysis 8No evidence of long-run relationship between the level of property prices and level of income is found by in
Gallin (2006) Therefore we intend to investigate this issue by involving log transformation of income (Ermini and Hendry2008)
15
purchase intention of houses In this empirical framework the ratio of house
price index to rental price index is used to proxy the house prices appreciation
And it is lagged one period to reduce simultaneity
Bank specific explanatory variables
The interest rate as an indicator of monetary policy is another widely
accepted explanatory variable9 It is calculated as the ratio of total interest
revenue over to interest bearing assets of individual banks A declining interest
rate environment contributes to the increasing demand for real estate and
housing investment (Greenand Shoven1986 Kearl1979 Tsatsaronis and Zhu
2004) In terms of Chinese housing market Liang and Cao (2007) suggest that
the property price movements have no sensitivity to the change of the real
interest rate By involving the rate of interest we reinvestigate to what extend
the raising interest rate can affect the mortgage credits and property prices
The required reserves are required to hold by commercial banks in the form of
deposits at the central bank Over the past decade along with the soaring
property prices and mortgage credit boom the central bank has raised the
required reserve ratio several times from 6 in 1999 to 20 in 2011 It is
viewed as another frequently used monetary policy other than the interest
9Hofmann (2003) concludes that real interest rate is more closely associated with property prices than with bank
lendingWolswijk (2006) and Eacutegertand Mihaljek (2007) confirm the negative effect of interest rate on houses prices in 15 EU countries and Eastern Europe
16
rate in China We explore in our paper whether the change of bank required
reserves has an impact on the movements of properties and mortgage credits
And we will compare the real effect of interest rate and required reserve ratio
We use one period lag transformation to reduce simultaneity
Loan_to_asset ratio is an important measure of balance sheet risk of individual
banks Since banks can not grant credit at all costs they need to conduct credit
audit and monitoring effectively in order to maintain low levels of
non-performing loans and increase margins (Abreuand Mendes 2001) In spite
of a positive relationship between Loan to deposit ratio and bank profitability
a high loan to deposit ratio is a warning sign of bankrsquos loan risk and then
discourage credit expansion In order to reduce simultaneity one period
lagged Loan_to_asset ratio is employed to capture the real effect of banksrsquo risk
taking behavior NIM is referred to as the net yield on interest-earning assets
and an indicator of profitability of a bankrsquos lending activities10 In addition
NIM is also a proxy of bank performance and profitability for Chinese banking
sector (Matthews 2009) We would like to test the favor of individual banks on
mortgage profits
Property prices as explanatory variables
The growth of four different property prices is employed in the empirical

Hanweck and Ryu (2005) capture NIM dynamics in response to unanticipated credit and find negative relationship between NIM and expected credit loss

framework They are condominium price the average real estate price and an
indicator of the whole property market residential price the indicator of solo
residential market high_grade houses price a measure of luxury and high-end
real estate market and economic houses price the price of affordable houses
for low-and-medium wage households Crone and Voith(1992) compare five
popular methods to estimate house price appreciation and conclude that the
mean sales price is least affected by the sample size and more accurate than
other estimating methods We aim to investigate the impact of different prices
on the change of mortgage separately The same as disposable income and
mortgage outstanding property prices are converted to logarithm form in
order to avoid heteroscedasticity problem Figure 4 illustrates the movements
of property prices in four separate real estate market
4 Results
41 Mortgage loans
The determinants mortgage lending are illustrated in table 3 from which we
test our hypotheses proposed in section 31
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
Our findings so far suggest that the volume of outstanding mortgage loans
increases with housing prices expect for the economic housing market which
is not surprising and in line with most recent evidence of developed countries
18
However we argue that the elasticity of condominium (and residential) price
to mortgage credits is around 17 which is much higher than that of other
countries 11 The condominium and residential prices illustrate a similar
impact on the mortgage lending It is simply because after the housing
reformation in 1998 all work units are not allowed to provide welfare houses
to employees As a result the fully market-oriented residential houses
contribute the majority of condominium supply in housing market and their
prices also follows similar movements On the other hand we find a contrary
result for economical house price which has a negative impact on mortgage
movements Since the economic houses focus on the market of medium amp
low income households and new migrants the increased price will weaken
the affordability of some potential buyer and vice versa The fallen price is
favored by more potential buyers most of whom need to rely on the
mortgages to finance their house purchasing
H2 Does the process of urbanisation has a positive effect on the mortgage
credits
The results of our estimation also support our second hypothesis Over the
past two decades China has been witnessing rapid urbanisation more and
more new immigrants choose to settle down in cities This massive internal
migration has brought about more potential home buyers and contributed to
11
The impact of housing price on mortgage credits is tested to be 05 for Ireland 062 for Spain and 075 for European Area (Fitzpatrick and McQuinn 2007 CarboValverde and Francisco Rodriguez 2010 Annett 2005)
19
the mortgage credit boom in China This impact of urbanisation is appreciable
which is reflected by the greater correlation coefficients of population than
other variables in our results Another interesting feature is that the change of
urban population has a more significant impact on the economic housing
market Since the purchasing power of new migrants is not as strong as city
natives the economical houses are of more concern to them and are more
sensitive to the change of urban population
In terms of monetary policies we found the interest rate is increasing with the
mortgage loans It tells us that the raising interest rate have little effect on
controlling the credit boom in China By contrast a negative correlation
between banksrsquo mortgage loans and required reserves for condominium and
residential markets is observed However the required reserves can neither
curb the credit boom for High_Grade and economic housing markets It
implies that although bankers were bracing for a slowdown in home loans
raising required reserves is not a good enough reason for them to curb their
loan to the High_Grade and economic houses mortgages which they view as
health asset in their portfolio Then we argue that compared with interest
tool the required reserve ratio is a relative effective instrument in controlling
the mortgage boom
20
CPI is the index of composite consumption goods12Increased CPI implies a
higher living expenditure which undermines the individualrsquos risk taking
intention of long-term mortgage loans And its impact on High_Grade and
economic housing markets is more significant In addition we found another
notable phenomenon is neither the net interest margin nor the loan to deposit
ratio affects the banksrsquo mortgage loans It tells us that the lending behavior of
Chinese commercial banks is more market-oriented rather not risk- or
profit-adjusted
42 House Prices
The determinants of housing price are illustrated in table 4 We can find that
the mortgage loan has a significant impact on the property prices The effect
on condominium and residential prices is positive which implies the
procyclical behavior of credits boom and condominium prices as a general
However the prices of High_Grade and Economical Houses have illustrated an
entirely different response to mortgage credits The economic houses in China
are also referred to as capped-price houses whose price is more
administrative interference rather not fully market-oriented And the market
of High_Grade properties features the high rigidity The movements of these
two special property markets cannot meet the boom of mortgage credits
12
According to the National Statistic Bureau of China property price is not calculated into CPI
21
Although the raising reserve ratio has little effect the interest rate moves
negative to the condominium prices and plays an active role in restraining the
housing prices We do not find significant impact of Housing Stock expected
appreciation rate of housing price and CPI on the movements of housing
prices
5 Conclusion
We use a bank level data set and panel data approach to gain insight in the
factors determining the growth of mortgage lending and housing prices Based
on Two-Stage Least SquaredInstrumental Variable approach the evidence of
relationship between house prices and mortgage credits is found We
document the positive impact of urbanization effect on the growth of
mortgage lending In terms of monetary policy we find negative effects of
required reserves on the change of mortgage credits and the interest rate on
property prices but not vice versa Our findings have important policy
implications and account for the existing monetary policies which are
implemented in China

user costs and investigates the arbitrage between occupied and rental housing
market It is attractive to those countries such as the US in which rent is
market-oriented
Although the previous work using a bank-level data is not much Davis and Zhu
(2009) employ a sample of micro data from 904 banks in 17 countries during
the period 1989-2002 and find strong correlation between bank credits and
commercial property in those countries which experienced crises linked to
property loss by banks To my knowledge there has been no previous research
that investigates the Chinese case using a bank level data Our paper
supplements the existing literature in three ways First a unique bank-level
mortgage data - which consists of a sample of 28 Chinese domestic
commercial banks during the period 2003-2009 - is employed for the empirical
analysis Second we estimate the nexus between the mortgage credits boom
and four different housing prices Finally we include the urbalisation and
monetary policy indices to capture the effects of socio-demographic change
and regulatory constraints respectively
3 Data Description and methodology
31 Methodology
We aim to investigate the interrelation between bank mortgage and property
markets and test two hypotheses below
7
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
H2 Does The process of urbanisation have a positive effect on the mortgage
credits
In addition along with the credit boom the central bank has carried out
different monetary policies to intervene with the property and mortgage
market indirectly We also test the real effect of interest instrument and
required reserve ratio on both housing prices and mortgage lending In order
to test the hypotheses above we first propose the model of banksrsquo and
borrowersrsquo behavior in the context of house financing through mortgage
lending
Borrowerrsquos behavior
Assume there are two goods house occupation and a composite consumption
good We use Cobb-Douglas utility function to analyze borrowerrsquos behavior
1U X Y
Where U denotes the utility of a borrower X is the consumption of composite
good and Y is the house occupation of the household Considering the
monotonicity of utility function we take logarithmic transformation and α is
the indicator of house purchase intension
log log (1 ) logU X Y
Suppose the household use mortgage loan to finance the house occupation
8
and dispensable income to support the consumption of house service and
composite good Then we can get borrowerrsquos maximum utility under the
constraint of dispensable income
max log log (1 ) logX Y U X Y
st [1 ( )]X r i M I
M P Y
Where I represents the dispensable income of borrower r is the real interest
rate of individual banks i denotes the inflation rate M is the total mortgage
loans P is the house price Optimal allocation is solved through Lagrange
function
log (1 ) log [ (1 ) ]L X Y X r i P Y I
Thesis of the Lagrange function is shown as follows
0
1(1 ) 0
(1 ) 0

Lr i P
Y Y
LX r i P Y I
By solving the linear equation system above with three unknowns which are P
M and λ respectively we get
(1 )
(1 )
IM P Y
r i
From the equation of M we argue that Mortgage demand increases with
9
borrowerrsquos income and house price but decreases with house purchase
intension and the interest rate In addition inflation has a positive impact on
mortgage demanding
Bankrsquos behavior
We assume the whole deposits of banks are interest-bearing assets She
allocates a proportion of its total Deposits on mortgage loans The total
mortgage lending is denoted as Y which is equal to consumersrsquo demanding of
mortgage loans The Loan_To_Deposit ratio is θ Then the mortgage can be
rewritten as Y D An individual bank enjoys an interest rate r on its
mortgage loans On the other hand she has to pay out the interest rate dr on
its deposits The lending business of individual bank incurs costs C which is
explained as a quadratic function 2( ) (1 )C Y c Y The individual bank aims to
maximize its total profits which is denoted as Then the maximization
function can be outlined as follows
2max [1 ] dr M N c Y r D
with M N P Y
D M
Then we plug M and D into our target function and get

supply provided by the bank increases with its NIM the number of mortgagers
(N) housing price (P) and decrease with its Loan_To_Deposit ratio (θ)
Econometric approach
Based on the theoretical analysis above we propose an empirical framework
to estimate the movements of mortgage lending as follows
1 1 1Mortgage Pop Interest Rate Inflation NIM LTD House Prices it it it it i t i t it itf RR
The index of potential mortgagers is Pop which is estimated by the
percentage of urban population to total population in China It also refers to
the effect of urbanization and internal migration Inflation and House Prices
are macroeconomic factors which have potential impact on the mortgage
market NIM LTD represents the Net Interest Margins and Loan to Deposit
ratio These variables reflect the characteristics of individual banks Interest
Rate and RR the Required Reserves of banks are proxies of monetary policy
constraints
11
Previous research also indicates that House price is rather an endogenous
variable and driven by market factors including creditmortgage rationing
Inverted demand equation is then widely used to estimate the house prices
We employ a simplified version of the house price model which is proposed by
Muellbauer and Murphy (1997) 4
( )HS Pop f I D
( )eP r P P
Where is the real user cost of housing services P is the real housing price
and eP P is the expected appreciation rate of housing price5 Muellbauer
and Murphy (1997) also pointed out that a proxy for creditmortgage
rationing is often included in the measurement housing price Substituting the
user cost into the housing stock function and involve the proxy of credit
conditions we can get the invert demand function to obtain the estimation of
P
( _ )eP f HS P P I credit rationing
Where HS eP P and I represent the housing stock expected appreciation
rate of housing price and the Income respectively Here in our frame we
employ the ratio of house price to house rental index to proxy the
appreciation rate Although the down payment ratio is a good and popular
index of credit rationing Chinese housing financing system has not
4Dougherty and Order investigate the measurement of the housing cost through two alternative approaches
They deduct the capital cost by maximizing household utility or implicit rent of the landlord and come up with the same results 5 Murphy also pointed that the long-run price-to-rent ratio can be estimated by real user cost and loan-to-value
ratio
12
experienced significant change of this ratio However the change of Mortgage
can partially reflect the bankrsquos credit rationing The increase of mortgage loans
is associated with loose credit rationing and lower interest rate Therefore we
employ the change of mortgage to proxy the credit rationing index Taking
into account the estimation of mortgage lending we form a simultaneous
equation system as follows to estimate mortgage loans and endogenous
housing prices Considering the bank-level mortgage loan data panel data
approach and two-stage least squaresInstrument variable method are
employed in our estimation

32 Data description
Compared with developed countries Chinese mortgage market has a relative
short history and therefore limited data available In this paper an unbalanced
panel of annual mortgage loans of Commercial Banks is employed for the
analysis 6 Our sample consists of all State-Owned-Banks (SOBs)
Joint-Stock-Banks (JSBs) and major City-Commercial-Banks (CCBs) The sum of
mortgage credits in our sample covers more than 80 of total mortgage
outstanding which makes our sample highly representative Therefore fixed
effect model is more appropriate to control for the individual heterogeneity
6Since the financial reform in Chinese banking sector and new enforcement of information disclosure by China
Bank Regulatory Commission the mortgage data for some banks in early years is not available
13
Next we carefully select conventional explanatory variables for our empirical
analysis so as to ensure our estimation is robust to omitted variables The
variables included in the empirical framework are described in groups as
follows The macro data which is collected from the Peoplersquos Bank of China
and National Bureau of Statistics of China Mortgage loans bank specific
variables and house prices are collected from ALMANAC OF CHINAS FINANCE
AND BANKING which is the official publication of Peoplersquos Bank of China
Dependent variables
We are more interested in the movements of mortgage loan and housing
prices within a given year Therefore the change of mortgage loans of
individual banks and housing prices are employed as the dependent variable
In addition log transformation of mortgage loans is employed In order to
avoid heteroscedasticity
Macroeconomic explanatory variables
Although GDP is a popular variable to assess the macroeconomic situation
(Liang and Cao 2007 Davis and Zhu 2010) a large body of literature explores
the impact of disposable income as an alternative McQuinn and OrsquoReilly
(2007) Hill and Gan(2008) established the relationship between income and
house price from both theoretical and empirical sides7 Urban disposable
7Other existing researches also corroborate the potent influence of household income on the dynamics of
housing prices see Jud and Winkler 2002 Gimeno and Martinez-Carrascal 2006 Bourassa and Hoesli2006
14
Income is appropriate to analyse the movement of property prices We
employ the national average deposable income for SOBs and JSBs given their
nationwide business line and local average disposable income for CCBs
considering their local market focus In addition urban disposable income is
log transformed in order to avoid heteroscedasticity problem8
Urbanization is another factor of our interests that may drive the movement of
mortgage credits Over the past decade China has experienced a dramatic
process of industrialisation and urbanisation And Comparing with
industrialisation Chinas urbanisation developed more rapidly (Zheng et al
2007) More and more new immigrants moved into cities Taking into account
more potential home buyers a higher volume of mortgage loans is expected
We use the percentage of urban population to total population to capture the
effect of urbanisation
House stock refers to the number of existing residential units It is also
considered as the response to the land-use regulation through the elasticity of
new housing supply (Quigley and Raphael 2005) In our empirical analysis we
employ the number of house sales to proxy the housing stocks Furthermore
the expected rate of appreciation of house prices reflects consumersrsquo
Nevertheless some other literatures are not in favor of this point of viewGallin (2006) analyzes a panel of 95 US metropolitan areas over 23 years and does not find evidence of long-run relationship between the property prices and income in level This result is also proved by Tsatsaronis and Zhu (2004) who find little impact of household income on housing prices in their cross-country analysis 8No evidence of long-run relationship between the level of property prices and level of income is found by in
Gallin (2006) Therefore we intend to investigate this issue by involving log transformation of income (Ermini and Hendry2008)
15
purchase intention of houses In this empirical framework the ratio of house
price index to rental price index is used to proxy the house prices appreciation
And it is lagged one period to reduce simultaneity
Bank specific explanatory variables
The interest rate as an indicator of monetary policy is another widely
accepted explanatory variable9 It is calculated as the ratio of total interest
revenue over to interest bearing assets of individual banks A declining interest
rate environment contributes to the increasing demand for real estate and
housing investment (Greenand Shoven1986 Kearl1979 Tsatsaronis and Zhu
2004) In terms of Chinese housing market Liang and Cao (2007) suggest that
the property price movements have no sensitivity to the change of the real
interest rate By involving the rate of interest we reinvestigate to what extend
the raising interest rate can affect the mortgage credits and property prices
The required reserves are required to hold by commercial banks in the form of
deposits at the central bank Over the past decade along with the soaring
property prices and mortgage credit boom the central bank has raised the
required reserve ratio several times from 6 in 1999 to 20 in 2011 It is
viewed as another frequently used monetary policy other than the interest
9Hofmann (2003) concludes that real interest rate is more closely associated with property prices than with bank
lendingWolswijk (2006) and Eacutegertand Mihaljek (2007) confirm the negative effect of interest rate on houses prices in 15 EU countries and Eastern Europe
16
rate in China We explore in our paper whether the change of bank required
reserves has an impact on the movements of properties and mortgage credits
And we will compare the real effect of interest rate and required reserve ratio
We use one period lag transformation to reduce simultaneity
Loan_to_asset ratio is an important measure of balance sheet risk of individual
banks Since banks can not grant credit at all costs they need to conduct credit
audit and monitoring effectively in order to maintain low levels of
non-performing loans and increase margins (Abreuand Mendes 2001) In spite
of a positive relationship between Loan to deposit ratio and bank profitability
a high loan to deposit ratio is a warning sign of bankrsquos loan risk and then
discourage credit expansion In order to reduce simultaneity one period
lagged Loan_to_asset ratio is employed to capture the real effect of banksrsquo risk
taking behavior NIM is referred to as the net yield on interest-earning assets
and an indicator of profitability of a bankrsquos lending activities10 In addition
NIM is also a proxy of bank performance and profitability for Chinese banking
sector (Matthews 2009) We would like to test the favor of individual banks on
mortgage profits
Property prices as explanatory variables
The growth of four different property prices is employed in the empirical

Hanweck and Ryu (2005) capture NIM dynamics in response to unanticipated credit and find negative relationship between NIM and expected credit loss

framework They are condominium price the average real estate price and an
indicator of the whole property market residential price the indicator of solo
residential market high_grade houses price a measure of luxury and high-end
real estate market and economic houses price the price of affordable houses
for low-and-medium wage households Crone and Voith(1992) compare five
popular methods to estimate house price appreciation and conclude that the
mean sales price is least affected by the sample size and more accurate than
other estimating methods We aim to investigate the impact of different prices
on the change of mortgage separately The same as disposable income and
mortgage outstanding property prices are converted to logarithm form in
order to avoid heteroscedasticity problem Figure 4 illustrates the movements
of property prices in four separate real estate market
4 Results
41 Mortgage loans
The determinants mortgage lending are illustrated in table 3 from which we
test our hypotheses proposed in section 31
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
Our findings so far suggest that the volume of outstanding mortgage loans
increases with housing prices expect for the economic housing market which
is not surprising and in line with most recent evidence of developed countries
18
However we argue that the elasticity of condominium (and residential) price
to mortgage credits is around 17 which is much higher than that of other
countries 11 The condominium and residential prices illustrate a similar
impact on the mortgage lending It is simply because after the housing
reformation in 1998 all work units are not allowed to provide welfare houses
to employees As a result the fully market-oriented residential houses
contribute the majority of condominium supply in housing market and their
prices also follows similar movements On the other hand we find a contrary
result for economical house price which has a negative impact on mortgage
movements Since the economic houses focus on the market of medium amp
low income households and new migrants the increased price will weaken
the affordability of some potential buyer and vice versa The fallen price is
favored by more potential buyers most of whom need to rely on the
mortgages to finance their house purchasing
H2 Does the process of urbanisation has a positive effect on the mortgage
credits
The results of our estimation also support our second hypothesis Over the
past two decades China has been witnessing rapid urbanisation more and
more new immigrants choose to settle down in cities This massive internal
migration has brought about more potential home buyers and contributed to
11
The impact of housing price on mortgage credits is tested to be 05 for Ireland 062 for Spain and 075 for European Area (Fitzpatrick and McQuinn 2007 CarboValverde and Francisco Rodriguez 2010 Annett 2005)
19
the mortgage credit boom in China This impact of urbanisation is appreciable
which is reflected by the greater correlation coefficients of population than
other variables in our results Another interesting feature is that the change of
urban population has a more significant impact on the economic housing
market Since the purchasing power of new migrants is not as strong as city
natives the economical houses are of more concern to them and are more
sensitive to the change of urban population
In terms of monetary policies we found the interest rate is increasing with the
mortgage loans It tells us that the raising interest rate have little effect on
controlling the credit boom in China By contrast a negative correlation
between banksrsquo mortgage loans and required reserves for condominium and
residential markets is observed However the required reserves can neither
curb the credit boom for High_Grade and economic housing markets It
implies that although bankers were bracing for a slowdown in home loans
raising required reserves is not a good enough reason for them to curb their
loan to the High_Grade and economic houses mortgages which they view as
health asset in their portfolio Then we argue that compared with interest
tool the required reserve ratio is a relative effective instrument in controlling
the mortgage boom
20
CPI is the index of composite consumption goods12Increased CPI implies a
higher living expenditure which undermines the individualrsquos risk taking
intention of long-term mortgage loans And its impact on High_Grade and
economic housing markets is more significant In addition we found another
notable phenomenon is neither the net interest margin nor the loan to deposit
ratio affects the banksrsquo mortgage loans It tells us that the lending behavior of
Chinese commercial banks is more market-oriented rather not risk- or
profit-adjusted
42 House Prices
The determinants of housing price are illustrated in table 4 We can find that
the mortgage loan has a significant impact on the property prices The effect
on condominium and residential prices is positive which implies the
procyclical behavior of credits boom and condominium prices as a general
However the prices of High_Grade and Economical Houses have illustrated an
entirely different response to mortgage credits The economic houses in China
are also referred to as capped-price houses whose price is more
administrative interference rather not fully market-oriented And the market
of High_Grade properties features the high rigidity The movements of these
two special property markets cannot meet the boom of mortgage credits
12
According to the National Statistic Bureau of China property price is not calculated into CPI
21
Although the raising reserve ratio has little effect the interest rate moves
negative to the condominium prices and plays an active role in restraining the
housing prices We do not find significant impact of Housing Stock expected
appreciation rate of housing price and CPI on the movements of housing
prices
5 Conclusion
We use a bank level data set and panel data approach to gain insight in the
factors determining the growth of mortgage lending and housing prices Based
on Two-Stage Least SquaredInstrumental Variable approach the evidence of
relationship between house prices and mortgage credits is found We
document the positive impact of urbanization effect on the growth of
mortgage lending In terms of monetary policy we find negative effects of
required reserves on the change of mortgage credits and the interest rate on
property prices but not vice versa Our findings have important policy
implications and account for the existing monetary policies which are
implemented in China

H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
H2 Does The process of urbanisation have a positive effect on the mortgage
credits
In addition along with the credit boom the central bank has carried out
different monetary policies to intervene with the property and mortgage
market indirectly We also test the real effect of interest instrument and
required reserve ratio on both housing prices and mortgage lending In order
to test the hypotheses above we first propose the model of banksrsquo and
borrowersrsquo behavior in the context of house financing through mortgage
lending
Borrowerrsquos behavior
Assume there are two goods house occupation and a composite consumption
good We use Cobb-Douglas utility function to analyze borrowerrsquos behavior
1U X Y
Where U denotes the utility of a borrower X is the consumption of composite
good and Y is the house occupation of the household Considering the
monotonicity of utility function we take logarithmic transformation and α is
the indicator of house purchase intension
log log (1 ) logU X Y
Suppose the household use mortgage loan to finance the house occupation
8
and dispensable income to support the consumption of house service and
composite good Then we can get borrowerrsquos maximum utility under the
constraint of dispensable income
max log log (1 ) logX Y U X Y
st [1 ( )]X r i M I
M P Y
Where I represents the dispensable income of borrower r is the real interest
rate of individual banks i denotes the inflation rate M is the total mortgage
loans P is the house price Optimal allocation is solved through Lagrange
function
log (1 ) log [ (1 ) ]L X Y X r i P Y I
Thesis of the Lagrange function is shown as follows
0
1(1 ) 0

Lr i P
Y Y
LX r i P Y I
By solving the linear equation system above with three unknowns which are P
M and λ respectively we get

IM P Y
r i
From the equation of M we argue that Mortgage demand increases with
9
borrowerrsquos income and house price but decreases with house purchase
intension and the interest rate In addition inflation has a positive impact on
mortgage demanding
Bankrsquos behavior
We assume the whole deposits of banks are interest-bearing assets She
allocates a proportion of its total Deposits on mortgage loans The total
mortgage lending is denoted as Y which is equal to consumersrsquo demanding of
mortgage loans The Loan_To_Deposit ratio is θ Then the mortgage can be
rewritten as Y D An individual bank enjoys an interest rate r on its
mortgage loans On the other hand she has to pay out the interest rate dr on
its deposits The lending business of individual bank incurs costs C which is
explained as a quadratic function 2( ) (1 )C Y c Y The individual bank aims to
maximize its total profits which is denoted as Then the maximization
function can be outlined as follows
2max [1 ] dr M N c Y r D
with M N P Y
D M
Then we plug M and D into our target function and get

supply provided by the bank increases with its NIM the number of mortgagers
(N) housing price (P) and decrease with its Loan_To_Deposit ratio (θ)
Econometric approach
Based on the theoretical analysis above we propose an empirical framework
to estimate the movements of mortgage lending as follows
1 1 1Mortgage Pop Interest Rate Inflation NIM LTD House Prices it it it it i t i t it itf RR
The index of potential mortgagers is Pop which is estimated by the
percentage of urban population to total population in China It also refers to
the effect of urbanization and internal migration Inflation and House Prices
are macroeconomic factors which have potential impact on the mortgage
market NIM LTD represents the Net Interest Margins and Loan to Deposit
ratio These variables reflect the characteristics of individual banks Interest
Rate and RR the Required Reserves of banks are proxies of monetary policy
constraints
11
Previous research also indicates that House price is rather an endogenous
variable and driven by market factors including creditmortgage rationing
Inverted demand equation is then widely used to estimate the house prices
We employ a simplified version of the house price model which is proposed by
Muellbauer and Murphy (1997) 4
( )HS Pop f I D
( )eP r P P
Where is the real user cost of housing services P is the real housing price
and eP P is the expected appreciation rate of housing price5 Muellbauer
and Murphy (1997) also pointed out that a proxy for creditmortgage
rationing is often included in the measurement housing price Substituting the
user cost into the housing stock function and involve the proxy of credit
conditions we can get the invert demand function to obtain the estimation of
P
( _ )eP f HS P P I credit rationing
Where HS eP P and I represent the housing stock expected appreciation
rate of housing price and the Income respectively Here in our frame we
employ the ratio of house price to house rental index to proxy the
appreciation rate Although the down payment ratio is a good and popular
index of credit rationing Chinese housing financing system has not
4Dougherty and Order investigate the measurement of the housing cost through two alternative approaches
They deduct the capital cost by maximizing household utility or implicit rent of the landlord and come up with the same results 5 Murphy also pointed that the long-run price-to-rent ratio can be estimated by real user cost and loan-to-value
ratio
12
experienced significant change of this ratio However the change of Mortgage
can partially reflect the bankrsquos credit rationing The increase of mortgage loans
is associated with loose credit rationing and lower interest rate Therefore we
employ the change of mortgage to proxy the credit rationing index Taking
into account the estimation of mortgage lending we form a simultaneous
equation system as follows to estimate mortgage loans and endogenous
housing prices Considering the bank-level mortgage loan data panel data
approach and two-stage least squaresInstrument variable method are
employed in our estimation

32 Data description
Compared with developed countries Chinese mortgage market has a relative
short history and therefore limited data available In this paper an unbalanced
panel of annual mortgage loans of Commercial Banks is employed for the
analysis 6 Our sample consists of all State-Owned-Banks (SOBs)
Joint-Stock-Banks (JSBs) and major City-Commercial-Banks (CCBs) The sum of
mortgage credits in our sample covers more than 80 of total mortgage
outstanding which makes our sample highly representative Therefore fixed
effect model is more appropriate to control for the individual heterogeneity
6Since the financial reform in Chinese banking sector and new enforcement of information disclosure by China
Bank Regulatory Commission the mortgage data for some banks in early years is not available
13
Next we carefully select conventional explanatory variables for our empirical
analysis so as to ensure our estimation is robust to omitted variables The
variables included in the empirical framework are described in groups as
follows The macro data which is collected from the Peoplersquos Bank of China
and National Bureau of Statistics of China Mortgage loans bank specific
variables and house prices are collected from ALMANAC OF CHINAS FINANCE
AND BANKING which is the official publication of Peoplersquos Bank of China
Dependent variables
We are more interested in the movements of mortgage loan and housing
prices within a given year Therefore the change of mortgage loans of
individual banks and housing prices are employed as the dependent variable
In addition log transformation of mortgage loans is employed In order to
avoid heteroscedasticity
Macroeconomic explanatory variables
Although GDP is a popular variable to assess the macroeconomic situation
(Liang and Cao 2007 Davis and Zhu 2010) a large body of literature explores
the impact of disposable income as an alternative McQuinn and OrsquoReilly
(2007) Hill and Gan(2008) established the relationship between income and
house price from both theoretical and empirical sides7 Urban disposable
7Other existing researches also corroborate the potent influence of household income on the dynamics of
housing prices see Jud and Winkler 2002 Gimeno and Martinez-Carrascal 2006 Bourassa and Hoesli2006
14
Income is appropriate to analyse the movement of property prices We
employ the national average deposable income for SOBs and JSBs given their
nationwide business line and local average disposable income for CCBs
considering their local market focus In addition urban disposable income is
log transformed in order to avoid heteroscedasticity problem8
Urbanization is another factor of our interests that may drive the movement of
mortgage credits Over the past decade China has experienced a dramatic
process of industrialisation and urbanisation And Comparing with
industrialisation Chinas urbanisation developed more rapidly (Zheng et al
2007) More and more new immigrants moved into cities Taking into account
more potential home buyers a higher volume of mortgage loans is expected
We use the percentage of urban population to total population to capture the
effect of urbanisation
House stock refers to the number of existing residential units It is also
considered as the response to the land-use regulation through the elasticity of
new housing supply (Quigley and Raphael 2005) In our empirical analysis we
employ the number of house sales to proxy the housing stocks Furthermore
the expected rate of appreciation of house prices reflects consumersrsquo
Nevertheless some other literatures are not in favor of this point of viewGallin (2006) analyzes a panel of 95 US metropolitan areas over 23 years and does not find evidence of long-run relationship between the property prices and income in level This result is also proved by Tsatsaronis and Zhu (2004) who find little impact of household income on housing prices in their cross-country analysis 8No evidence of long-run relationship between the level of property prices and level of income is found by in
Gallin (2006) Therefore we intend to investigate this issue by involving log transformation of income (Ermini and Hendry2008)
15
purchase intention of houses In this empirical framework the ratio of house
price index to rental price index is used to proxy the house prices appreciation
And it is lagged one period to reduce simultaneity
Bank specific explanatory variables
The interest rate as an indicator of monetary policy is another widely
accepted explanatory variable9 It is calculated as the ratio of total interest
revenue over to interest bearing assets of individual banks A declining interest
rate environment contributes to the increasing demand for real estate and
housing investment (Greenand Shoven1986 Kearl1979 Tsatsaronis and Zhu
2004) In terms of Chinese housing market Liang and Cao (2007) suggest that
the property price movements have no sensitivity to the change of the real
interest rate By involving the rate of interest we reinvestigate to what extend
the raising interest rate can affect the mortgage credits and property prices
The required reserves are required to hold by commercial banks in the form of
deposits at the central bank Over the past decade along with the soaring
property prices and mortgage credit boom the central bank has raised the
required reserve ratio several times from 6 in 1999 to 20 in 2011 It is
viewed as another frequently used monetary policy other than the interest
9Hofmann (2003) concludes that real interest rate is more closely associated with property prices than with bank
lendingWolswijk (2006) and Eacutegertand Mihaljek (2007) confirm the negative effect of interest rate on houses prices in 15 EU countries and Eastern Europe
16
rate in China We explore in our paper whether the change of bank required
reserves has an impact on the movements of properties and mortgage credits
And we will compare the real effect of interest rate and required reserve ratio
We use one period lag transformation to reduce simultaneity
Loan_to_asset ratio is an important measure of balance sheet risk of individual
banks Since banks can not grant credit at all costs they need to conduct credit
audit and monitoring effectively in order to maintain low levels of
non-performing loans and increase margins (Abreuand Mendes 2001) In spite
of a positive relationship between Loan to deposit ratio and bank profitability
a high loan to deposit ratio is a warning sign of bankrsquos loan risk and then
discourage credit expansion In order to reduce simultaneity one period
lagged Loan_to_asset ratio is employed to capture the real effect of banksrsquo risk
taking behavior NIM is referred to as the net yield on interest-earning assets
and an indicator of profitability of a bankrsquos lending activities10 In addition
NIM is also a proxy of bank performance and profitability for Chinese banking
sector (Matthews 2009) We would like to test the favor of individual banks on
mortgage profits
Property prices as explanatory variables
The growth of four different property prices is employed in the empirical

Hanweck and Ryu (2005) capture NIM dynamics in response to unanticipated credit and find negative relationship between NIM and expected credit loss
17
framework They are condominium price the average real estate price and an
indicator of the whole property market residential price the indicator of solo
residential market high_grade houses price a measure of luxury and high-end
real estate market and economic houses price the price of affordable houses
for low-and-medium wage households Crone and Voith(1992) compare five
popular methods to estimate house price appreciation and conclude that the
mean sales price is least affected by the sample size and more accurate than
other estimating methods We aim to investigate the impact of different prices
on the change of mortgage separately The same as disposable income and
mortgage outstanding property prices are converted to logarithm form in
order to avoid heteroscedasticity problem Figure 4 illustrates the movements
of property prices in four separate real estate market
4 Results
41 Mortgage loans
The determinants mortgage lending are illustrated in table 3 from which we
test our hypotheses proposed in section 31
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
Our findings so far suggest that the volume of outstanding mortgage loans
increases with housing prices expect for the economic housing market which
is not surprising and in line with most recent evidence of developed countries
18
However we argue that the elasticity of condominium (and residential) price
to mortgage credits is around 17 which is much higher than that of other
countries 11 The condominium and residential prices illustrate a similar
impact on the mortgage lending It is simply because after the housing
reformation in 1998 all work units are not allowed to provide welfare houses
to employees As a result the fully market-oriented residential houses
contribute the majority of condominium supply in housing market and their
prices also follows similar movements On the other hand we find a contrary
result for economical house price which has a negative impact on mortgage
movements Since the economic houses focus on the market of medium amp
low income households and new migrants the increased price will weaken
the affordability of some potential buyer and vice versa The fallen price is
favored by more potential buyers most of whom need to rely on the
mortgages to finance their house purchasing
H2 Does the process of urbanisation has a positive effect on the mortgage
credits
The results of our estimation also support our second hypothesis Over the
past two decades China has been witnessing rapid urbanisation more and
more new immigrants choose to settle down in cities This massive internal
migration has brought about more potential home buyers and contributed to
11
The impact of housing price on mortgage credits is tested to be 05 for Ireland 062 for Spain and 075 for European Area (Fitzpatrick and McQuinn 2007 CarboValverde and Francisco Rodriguez 2010 Annett 2005)
19
the mortgage credit boom in China This impact of urbanisation is appreciable
which is reflected by the greater correlation coefficients of population than
other variables in our results Another interesting feature is that the change of
urban population has a more significant impact on the economic housing
market Since the purchasing power of new migrants is not as strong as city
natives the economical houses are of more concern to them and are more
sensitive to the change of urban population
In terms of monetary policies we found the interest rate is increasing with the
mortgage loans It tells us that the raising interest rate have little effect on
controlling the credit boom in China By contrast a negative correlation
between banksrsquo mortgage loans and required reserves for condominium and
residential markets is observed However the required reserves can neither
curb the credit boom for High_Grade and economic housing markets It
implies that although bankers were bracing for a slowdown in home loans
raising required reserves is not a good enough reason for them to curb their
loan to the High_Grade and economic houses mortgages which they view as
health asset in their portfolio Then we argue that compared with interest
tool the required reserve ratio is a relative effective instrument in controlling
the mortgage boom
20
CPI is the index of composite consumption goods12Increased CPI implies a
higher living expenditure which undermines the individualrsquos risk taking
intention of long-term mortgage loans And its impact on High_Grade and
economic housing markets is more significant In addition we found another
notable phenomenon is neither the net interest margin nor the loan to deposit
ratio affects the banksrsquo mortgage loans It tells us that the lending behavior of
Chinese commercial banks is more market-oriented rather not risk- or
profit-adjusted
42 House Prices
The determinants of housing price are illustrated in table 4 We can find that
the mortgage loan has a significant impact on the property prices The effect
on condominium and residential prices is positive which implies the
procyclical behavior of credits boom and condominium prices as a general
However the prices of High_Grade and Economical Houses have illustrated an
entirely different response to mortgage credits The economic houses in China
are also referred to as capped-price houses whose price is more
administrative interference rather not fully market-oriented And the market
of High_Grade properties features the high rigidity The movements of these
two special property markets cannot meet the boom of mortgage credits
12
According to the National Statistic Bureau of China property price is not calculated into CPI
21
Although the raising reserve ratio has little effect the interest rate moves
negative to the condominium prices and plays an active role in restraining the
housing prices We do not find significant impact of Housing Stock expected
appreciation rate of housing price and CPI on the movements of housing
prices
5 Conclusion
We use a bank level data set and panel data approach to gain insight in the
factors determining the growth of mortgage lending and housing prices Based
on Two-Stage Least SquaredInstrumental Variable approach the evidence of
relationship between house prices and mortgage credits is found We
document the positive impact of urbanization effect on the growth of
mortgage lending In terms of monetary policy we find negative effects of
required reserves on the change of mortgage credits and the interest rate on
property prices but not vice versa Our findings have important policy
implications and account for the existing monetary policies which are
implemented in China

We assume the whole deposits of banks are interest-bearing assets She

Econometric approach
Based on the theoretical analysis above we propose an empirical framework
to estimate the movements of mortgage lending as follows
1 1 1Mortgage Pop Interest Rate Inflation NIM LTD House Prices it it it it i t i t it itf RR
The index of potential mortgagers is Pop which is estimated by the
percentage of urban population to total population in China It also refers to
the effect of urbanization and internal migration Inflation and House Prices
are macroeconomic factors which have potential impact on the mortgage
market NIM LTD represents the Net Interest Margins and Loan to Deposit
ratio These variables reflect the characteristics of individual banks Interest
Rate and RR the Required Reserves of banks are proxies of monetary policy
constraints
11
Previous research also indicates that House price is rather an endogenous
variable and driven by market factors including creditmortgage rationing
Inverted demand equation is then widely used to estimate the house prices
We employ a simplified version of the house price model which is proposed by
Muellbauer and Murphy (1997) 4

user cost into the housing stock function and involve the proxy of credit

Where HS eP P and I represent the housing stock expected appreciation

index of credit rationing Chinese housing financing system has not

ratio
12
experienced significant change of this ratio However the change of Mortgage
can partially reflect the bankrsquos credit rationing The increase of mortgage loans
is associated with loose credit rationing and lower interest rate Therefore we
employ the change of mortgage to proxy the credit rationing index Taking
into account the estimation of mortgage lending we form a simultaneous
equation system as follows to estimate mortgage loans and endogenous
housing prices Considering the bank-level mortgage loan data panel data

32 Data description
Compared with developed countries Chinese mortgage market has a relative
short history and therefore limited data available In this paper an unbalanced
panel of annual mortgage loans of Commercial Banks is employed for the
analysis 6 Our sample consists of all State-Owned-Banks (SOBs)
Joint-Stock-Banks (JSBs) and major City-Commercial-Banks (CCBs) The sum of
mortgage credits in our sample covers more than 80 of total mortgage
outstanding which makes our sample highly representative Therefore fixed
effect model is more appropriate to control for the individual heterogeneity
6Since the financial reform in Chinese banking sector and new enforcement of information disclosure by China
Bank Regulatory Commission the mortgage data for some banks in early years is not available
13
Next we carefully select conventional explanatory variables for our empirical
analysis so as to ensure our estimation is robust to omitted variables The
variables included in the empirical framework are described in groups as
follows The macro data which is collected from the Peoplersquos Bank of China
and National Bureau of Statistics of China Mortgage loans bank specific
variables and house prices are collected from ALMANAC OF CHINAS FINANCE
AND BANKING which is the official publication of Peoplersquos Bank of China
Dependent variables
We are more interested in the movements of mortgage loan and housing
prices within a given year Therefore the change of mortgage loans of
individual banks and housing prices are employed as the dependent variable
In addition log transformation of mortgage loans is employed In order to
avoid heteroscedasticity
Macroeconomic explanatory variables
Although GDP is a popular variable to assess the macroeconomic situation
(Liang and Cao 2007 Davis and Zhu 2010) a large body of literature explores
the impact of disposable income as an alternative McQuinn and OrsquoReilly
(2007) Hill and Gan(2008) established the relationship between income and
house price from both theoretical and empirical sides7 Urban disposable
7Other existing researches also corroborate the potent influence of household income on the dynamics of
housing prices see Jud and Winkler 2002 Gimeno and Martinez-Carrascal 2006 Bourassa and Hoesli2006
14
Income is appropriate to analyse the movement of property prices We
employ the national average deposable income for SOBs and JSBs given their
nationwide business line and local average disposable income for CCBs
considering their local market focus In addition urban disposable income is
log transformed in order to avoid heteroscedasticity problem8
Urbanization is another factor of our interests that may drive the movement of
mortgage credits Over the past decade China has experienced a dramatic
process of industrialisation and urbanisation And Comparing with
industrialisation Chinas urbanisation developed more rapidly (Zheng et al
2007) More and more new immigrants moved into cities Taking into account
more potential home buyers a higher volume of mortgage loans is expected
We use the percentage of urban population to total population to capture the
effect of urbanisation
House stock refers to the number of existing residential units It is also
considered as the response to the land-use regulation through the elasticity of
new housing supply (Quigley and Raphael 2005) In our empirical analysis we
employ the number of house sales to proxy the housing stocks Furthermore
the expected rate of appreciation of house prices reflects consumersrsquo
Nevertheless some other literatures are not in favor of this point of viewGallin (2006) analyzes a panel of 95 US metropolitan areas over 23 years and does not find evidence of long-run relationship between the property prices and income in level This result is also proved by Tsatsaronis and Zhu (2004) who find little impact of household income on housing prices in their cross-country analysis 8No evidence of long-run relationship between the level of property prices and level of income is found by in
Gallin (2006) Therefore we intend to investigate this issue by involving log transformation of income (Ermini and Hendry2008)
15
purchase intention of houses In this empirical framework the ratio of house
price index to rental price index is used to proxy the house prices appreciation
And it is lagged one period to reduce simultaneity
Bank specific explanatory variables
The interest rate as an indicator of monetary policy is another widely
accepted explanatory variable9 It is calculated as the ratio of total interest
revenue over to interest bearing assets of individual banks A declining interest
rate environment contributes to the increasing demand for real estate and
housing investment (Greenand Shoven1986 Kearl1979 Tsatsaronis and Zhu
2004) In terms of Chinese housing market Liang and Cao (2007) suggest that
the property price movements have no sensitivity to the change of the real
interest rate By involving the rate of interest we reinvestigate to what extend
the raising interest rate can affect the mortgage credits and property prices
The required reserves are required to hold by commercial banks in the form of
deposits at the central bank Over the past decade along with the soaring
property prices and mortgage credit boom the central bank has raised the
required reserve ratio several times from 6 in 1999 to 20 in 2011 It is
viewed as another frequently used monetary policy other than the interest
9Hofmann (2003) concludes that real interest rate is more closely associated with property prices than with bank
lendingWolswijk (2006) and Eacutegertand Mihaljek (2007) confirm the negative effect of interest rate on houses prices in 15 EU countries and Eastern Europe
16
rate in China We explore in our paper whether the change of bank required
reserves has an impact on the movements of properties and mortgage credits
And we will compare the real effect of interest rate and required reserve ratio
We use one period lag transformation to reduce simultaneity
Loan_to_asset ratio is an important measure of balance sheet risk of individual
banks Since banks can not grant credit at all costs they need to conduct credit
audit and monitoring effectively in order to maintain low levels of
non-performing loans and increase margins (Abreuand Mendes 2001) In spite
of a positive relationship between Loan to deposit ratio and bank profitability
a high loan to deposit ratio is a warning sign of bankrsquos loan risk and then
discourage credit expansion In order to reduce simultaneity one period
lagged Loan_to_asset ratio is employed to capture the real effect of banksrsquo risk
taking behavior NIM is referred to as the net yield on interest-earning assets
and an indicator of profitability of a bankrsquos lending activities10 In addition
NIM is also a proxy of bank performance and profitability for Chinese banking
sector (Matthews 2009) We would like to test the favor of individual banks on
mortgage profits
Property prices as explanatory variables
The growth of four different property prices is employed in the empirical

framework They are condominium price the average real estate price and an
indicator of the whole property market residential price the indicator of solo
residential market high_grade houses price a measure of luxury and high-end
real estate market and economic houses price the price of affordable houses
for low-and-medium wage households Crone and Voith(1992) compare five
popular methods to estimate house price appreciation and conclude that the
mean sales price is least affected by the sample size and more accurate than
other estimating methods We aim to investigate the impact of different prices
on the change of mortgage separately The same as disposable income and
mortgage outstanding property prices are converted to logarithm form in
order to avoid heteroscedasticity problem Figure 4 illustrates the movements
of property prices in four separate real estate market
4 Results
41 Mortgage loans
The determinants mortgage lending are illustrated in table 3 from which we
test our hypotheses proposed in section 31
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
Our findings so far suggest that the volume of outstanding mortgage loans
increases with housing prices expect for the economic housing market which
is not surprising and in line with most recent evidence of developed countries
18
However we argue that the elasticity of condominium (and residential) price
to mortgage credits is around 17 which is much higher than that of other
countries 11 The condominium and residential prices illustrate a similar
impact on the mortgage lending It is simply because after the housing
reformation in 1998 all work units are not allowed to provide welfare houses
to employees As a result the fully market-oriented residential houses
contribute the majority of condominium supply in housing market and their
prices also follows similar movements On the other hand we find a contrary
result for economical house price which has a negative impact on mortgage
movements Since the economic houses focus on the market of medium amp
low income households and new migrants the increased price will weaken
the affordability of some potential buyer and vice versa The fallen price is
favored by more potential buyers most of whom need to rely on the
mortgages to finance their house purchasing
H2 Does the process of urbanisation has a positive effect on the mortgage
credits
The results of our estimation also support our second hypothesis Over the
past two decades China has been witnessing rapid urbanisation more and
more new immigrants choose to settle down in cities This massive internal
migration has brought about more potential home buyers and contributed to
11
The impact of housing price on mortgage credits is tested to be 05 for Ireland 062 for Spain and 075 for European Area (Fitzpatrick and McQuinn 2007 CarboValverde and Francisco Rodriguez 2010 Annett 2005)
19
the mortgage credit boom in China This impact of urbanisation is appreciable
which is reflected by the greater correlation coefficients of population than
other variables in our results Another interesting feature is that the change of
urban population has a more significant impact on the economic housing
market Since the purchasing power of new migrants is not as strong as city
natives the economical houses are of more concern to them and are more
sensitive to the change of urban population
In terms of monetary policies we found the interest rate is increasing with the
mortgage loans It tells us that the raising interest rate have little effect on
controlling the credit boom in China By contrast a negative correlation
between banksrsquo mortgage loans and required reserves for condominium and
residential markets is observed However the required reserves can neither
curb the credit boom for High_Grade and economic housing markets It
implies that although bankers were bracing for a slowdown in home loans
raising required reserves is not a good enough reason for them to curb their
loan to the High_Grade and economic houses mortgages which they view as
health asset in their portfolio Then we argue that compared with interest
tool the required reserve ratio is a relative effective instrument in controlling
the mortgage boom
20
CPI is the index of composite consumption goods12Increased CPI implies a
higher living expenditure which undermines the individualrsquos risk taking
intention of long-term mortgage loans And its impact on High_Grade and
economic housing markets is more significant In addition we found another
notable phenomenon is neither the net interest margin nor the loan to deposit
ratio affects the banksrsquo mortgage loans It tells us that the lending behavior of
Chinese commercial banks is more market-oriented rather not risk- or
profit-adjusted
42 House Prices
The determinants of housing price are illustrated in table 4 We can find that
the mortgage loan has a significant impact on the property prices The effect
on condominium and residential prices is positive which implies the
procyclical behavior of credits boom and condominium prices as a general
However the prices of High_Grade and Economical Houses have illustrated an
entirely different response to mortgage credits The economic houses in China
are also referred to as capped-price houses whose price is more
administrative interference rather not fully market-oriented And the market
of High_Grade properties features the high rigidity The movements of these
two special property markets cannot meet the boom of mortgage credits
12
According to the National Statistic Bureau of China property price is not calculated into CPI
21
Although the raising reserve ratio has little effect the interest rate moves
negative to the condominium prices and plays an active role in restraining the
housing prices We do not find significant impact of Housing Stock expected
appreciation rate of housing price and CPI on the movements of housing
prices
5 Conclusion
We use a bank level data set and panel data approach to gain insight in the
factors determining the growth of mortgage lending and housing prices Based
on Two-Stage Least SquaredInstrumental Variable approach the evidence of
relationship between house prices and mortgage credits is found We
document the positive impact of urbanization effect on the growth of
mortgage lending In terms of monetary policy we find negative effects of
required reserves on the change of mortgage credits and the interest rate on
property prices but not vice versa Our findings have important policy
implications and account for the existing monetary policies which are
implemented in China

Bankrsquos behavior
We assume the whole deposits of banks are interest-bearing assets She
allocates a proportion of its total Deposits on mortgage loans The total
mortgage lending is denoted as Y which is equal to consumersrsquo demanding of
mortgage loans The Loan_To_Deposit ratio is θ Then the mortgage can be
rewritten as Y D An individual bank enjoys an interest rate r on its
mortgage loans On the other hand she has to pay out the interest rate dr on
its deposits The lending business of individual bank incurs costs C which is
explained as a quadratic function 2( ) (1 )C Y c Y The individual bank aims to
maximize its total profits which is denoted as Then the maximization
function can be outlined as follows

Econometric approach
Based on the theoretical analysis above we propose an empirical framework
to estimate the movements of mortgage lending as follows
1 1 1Mortgage Pop Interest Rate Inflation NIM LTD House Prices it it it it i t i t it itf RR
The index of potential mortgagers is Pop which is estimated by the
percentage of urban population to total population in China It also refers to
the effect of urbanization and internal migration Inflation and House Prices
are macroeconomic factors which have potential impact on the mortgage
market NIM LTD represents the Net Interest Margins and Loan to Deposit
ratio These variables reflect the characteristics of individual banks Interest
Rate and RR the Required Reserves of banks are proxies of monetary policy
constraints
11
Previous research also indicates that House price is rather an endogenous
variable and driven by market factors including creditmortgage rationing
Inverted demand equation is then widely used to estimate the house prices
We employ a simplified version of the house price model which is proposed by
Muellbauer and Murphy (1997) 4
( )HS Pop f I D

Where is the real user cost of housing services P is the real housing price

user cost into the housing stock function and involve the proxy of credit

Where HS eP P and I represent the housing stock expected appreciation

index of credit rationing Chinese housing financing system has not
4Dougherty and Order investigate the measurement of the housing cost through two alternative approaches

ratio
12
experienced significant change of this ratio However the change of Mortgage
can partially reflect the bankrsquos credit rationing The increase of mortgage loans
is associated with loose credit rationing and lower interest rate Therefore we
employ the change of mortgage to proxy the credit rationing index Taking
into account the estimation of mortgage lending we form a simultaneous
equation system as follows to estimate mortgage loans and endogenous
housing prices Considering the bank-level mortgage loan data panel data

32 Data description
Compared with developed countries Chinese mortgage market has a relative
short history and therefore limited data available In this paper an unbalanced
panel of annual mortgage loans of Commercial Banks is employed for the
analysis 6 Our sample consists of all State-Owned-Banks (SOBs)
Joint-Stock-Banks (JSBs) and major City-Commercial-Banks (CCBs) The sum of
mortgage credits in our sample covers more than 80 of total mortgage
outstanding which makes our sample highly representative Therefore fixed
effect model is more appropriate to control for the individual heterogeneity
6Since the financial reform in Chinese banking sector and new enforcement of information disclosure by China
Bank Regulatory Commission the mortgage data for some banks in early years is not available
13
Next we carefully select conventional explanatory variables for our empirical
analysis so as to ensure our estimation is robust to omitted variables The
variables included in the empirical framework are described in groups as
follows The macro data which is collected from the Peoplersquos Bank of China
and National Bureau of Statistics of China Mortgage loans bank specific
variables and house prices are collected from ALMANAC OF CHINAS FINANCE
AND BANKING which is the official publication of Peoplersquos Bank of China
Dependent variables
We are more interested in the movements of mortgage loan and housing
prices within a given year Therefore the change of mortgage loans of
individual banks and housing prices are employed as the dependent variable
In addition log transformation of mortgage loans is employed In order to
avoid heteroscedasticity
Macroeconomic explanatory variables
Although GDP is a popular variable to assess the macroeconomic situation
(Liang and Cao 2007 Davis and Zhu 2010) a large body of literature explores
the impact of disposable income as an alternative McQuinn and OrsquoReilly
(2007) Hill and Gan(2008) established the relationship between income and
house price from both theoretical and empirical sides7 Urban disposable
7Other existing researches also corroborate the potent influence of household income on the dynamics of
housing prices see Jud and Winkler 2002 Gimeno and Martinez-Carrascal 2006 Bourassa and Hoesli2006
14
Income is appropriate to analyse the movement of property prices We
employ the national average deposable income for SOBs and JSBs given their
nationwide business line and local average disposable income for CCBs
considering their local market focus In addition urban disposable income is
log transformed in order to avoid heteroscedasticity problem8
Urbanization is another factor of our interests that may drive the movement of
mortgage credits Over the past decade China has experienced a dramatic
process of industrialisation and urbanisation And Comparing with
industrialisation Chinas urbanisation developed more rapidly (Zheng et al
2007) More and more new immigrants moved into cities Taking into account
more potential home buyers a higher volume of mortgage loans is expected
We use the percentage of urban population to total population to capture the
effect of urbanisation
House stock refers to the number of existing residential units It is also
considered as the response to the land-use regulation through the elasticity of
new housing supply (Quigley and Raphael 2005) In our empirical analysis we
employ the number of house sales to proxy the housing stocks Furthermore
the expected rate of appreciation of house prices reflects consumersrsquo
Nevertheless some other literatures are not in favor of this point of viewGallin (2006) analyzes a panel of 95 US metropolitan areas over 23 years and does not find evidence of long-run relationship between the property prices and income in level This result is also proved by Tsatsaronis and Zhu (2004) who find little impact of household income on housing prices in their cross-country analysis 8No evidence of long-run relationship between the level of property prices and level of income is found by in
Gallin (2006) Therefore we intend to investigate this issue by involving log transformation of income (Ermini and Hendry2008)
15
purchase intention of houses In this empirical framework the ratio of house
price index to rental price index is used to proxy the house prices appreciation
And it is lagged one period to reduce simultaneity
Bank specific explanatory variables
The interest rate as an indicator of monetary policy is another widely
accepted explanatory variable9 It is calculated as the ratio of total interest
revenue over to interest bearing assets of individual banks A declining interest
rate environment contributes to the increasing demand for real estate and
housing investment (Greenand Shoven1986 Kearl1979 Tsatsaronis and Zhu
2004) In terms of Chinese housing market Liang and Cao (2007) suggest that
the property price movements have no sensitivity to the change of the real
interest rate By involving the rate of interest we reinvestigate to what extend
the raising interest rate can affect the mortgage credits and property prices
The required reserves are required to hold by commercial banks in the form of
deposits at the central bank Over the past decade along with the soaring
property prices and mortgage credit boom the central bank has raised the
required reserve ratio several times from 6 in 1999 to 20 in 2011 It is
viewed as another frequently used monetary policy other than the interest
9Hofmann (2003) concludes that real interest rate is more closely associated with property prices than with bank
lendingWolswijk (2006) and Eacutegertand Mihaljek (2007) confirm the negative effect of interest rate on houses prices in 15 EU countries and Eastern Europe
16
rate in China We explore in our paper whether the change of bank required
reserves has an impact on the movements of properties and mortgage credits
And we will compare the real effect of interest rate and required reserve ratio
We use one period lag transformation to reduce simultaneity
Loan_to_asset ratio is an important measure of balance sheet risk of individual
banks Since banks can not grant credit at all costs they need to conduct credit
audit and monitoring effectively in order to maintain low levels of
non-performing loans and increase margins (Abreuand Mendes 2001) In spite
of a positive relationship between Loan to deposit ratio and bank profitability
a high loan to deposit ratio is a warning sign of bankrsquos loan risk and then
discourage credit expansion In order to reduce simultaneity one period
lagged Loan_to_asset ratio is employed to capture the real effect of banksrsquo risk
taking behavior NIM is referred to as the net yield on interest-earning assets
and an indicator of profitability of a bankrsquos lending activities10 In addition
NIM is also a proxy of bank performance and profitability for Chinese banking
sector (Matthews 2009) We would like to test the favor of individual banks on
mortgage profits
Property prices as explanatory variables
The growth of four different property prices is employed in the empirical

framework They are condominium price the average real estate price and an
indicator of the whole property market residential price the indicator of solo
residential market high_grade houses price a measure of luxury and high-end
real estate market and economic houses price the price of affordable houses
for low-and-medium wage households Crone and Voith(1992) compare five
popular methods to estimate house price appreciation and conclude that the
mean sales price is least affected by the sample size and more accurate than
other estimating methods We aim to investigate the impact of different prices
on the change of mortgage separately The same as disposable income and
mortgage outstanding property prices are converted to logarithm form in
order to avoid heteroscedasticity problem Figure 4 illustrates the movements
of property prices in four separate real estate market
4 Results
41 Mortgage loans
The determinants mortgage lending are illustrated in table 3 from which we
test our hypotheses proposed in section 31
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
Our findings so far suggest that the volume of outstanding mortgage loans
increases with housing prices expect for the economic housing market which
is not surprising and in line with most recent evidence of developed countries
18
However we argue that the elasticity of condominium (and residential) price
to mortgage credits is around 17 which is much higher than that of other
countries 11 The condominium and residential prices illustrate a similar
impact on the mortgage lending It is simply because after the housing
reformation in 1998 all work units are not allowed to provide welfare houses
to employees As a result the fully market-oriented residential houses
contribute the majority of condominium supply in housing market and their
prices also follows similar movements On the other hand we find a contrary
result for economical house price which has a negative impact on mortgage
movements Since the economic houses focus on the market of medium amp
low income households and new migrants the increased price will weaken
the affordability of some potential buyer and vice versa The fallen price is
favored by more potential buyers most of whom need to rely on the
mortgages to finance their house purchasing
H2 Does the process of urbanisation has a positive effect on the mortgage
credits
The results of our estimation also support our second hypothesis Over the
past two decades China has been witnessing rapid urbanisation more and
more new immigrants choose to settle down in cities This massive internal
migration has brought about more potential home buyers and contributed to
11
The impact of housing price on mortgage credits is tested to be 05 for Ireland 062 for Spain and 075 for European Area (Fitzpatrick and McQuinn 2007 CarboValverde and Francisco Rodriguez 2010 Annett 2005)
19
the mortgage credit boom in China This impact of urbanisation is appreciable
which is reflected by the greater correlation coefficients of population than
other variables in our results Another interesting feature is that the change of
urban population has a more significant impact on the economic housing
market Since the purchasing power of new migrants is not as strong as city
natives the economical houses are of more concern to them and are more
sensitive to the change of urban population
In terms of monetary policies we found the interest rate is increasing with the
mortgage loans It tells us that the raising interest rate have little effect on
controlling the credit boom in China By contrast a negative correlation
between banksrsquo mortgage loans and required reserves for condominium and
residential markets is observed However the required reserves can neither
curb the credit boom for High_Grade and economic housing markets It
implies that although bankers were bracing for a slowdown in home loans
raising required reserves is not a good enough reason for them to curb their
loan to the High_Grade and economic houses mortgages which they view as
health asset in their portfolio Then we argue that compared with interest
tool the required reserve ratio is a relative effective instrument in controlling
the mortgage boom
20
CPI is the index of composite consumption goods12Increased CPI implies a
higher living expenditure which undermines the individualrsquos risk taking
intention of long-term mortgage loans And its impact on High_Grade and
economic housing markets is more significant In addition we found another
notable phenomenon is neither the net interest margin nor the loan to deposit
ratio affects the banksrsquo mortgage loans It tells us that the lending behavior of
Chinese commercial banks is more market-oriented rather not risk- or
profit-adjusted
42 House Prices
The determinants of housing price are illustrated in table 4 We can find that
the mortgage loan has a significant impact on the property prices The effect
on condominium and residential prices is positive which implies the
procyclical behavior of credits boom and condominium prices as a general
However the prices of High_Grade and Economical Houses have illustrated an
entirely different response to mortgage credits The economic houses in China
are also referred to as capped-price houses whose price is more
administrative interference rather not fully market-oriented And the market
of High_Grade properties features the high rigidity The movements of these
two special property markets cannot meet the boom of mortgage credits
12
According to the National Statistic Bureau of China property price is not calculated into CPI
21
Although the raising reserve ratio has little effect the interest rate moves
negative to the condominium prices and plays an active role in restraining the
housing prices We do not find significant impact of Housing Stock expected
appreciation rate of housing price and CPI on the movements of housing
prices
5 Conclusion
We use a bank level data set and panel data approach to gain insight in the
factors determining the growth of mortgage lending and housing prices Based
on Two-Stage Least SquaredInstrumental Variable approach the evidence of
relationship between house prices and mortgage credits is found We
document the positive impact of urbanization effect on the growth of
mortgage lending In terms of monetary policy we find negative effects of
required reserves on the change of mortgage credits and the interest rate on
property prices but not vice versa Our findings have important policy
implications and account for the existing monetary policies which are
implemented in China

Econometric approach
Based on the theoretical analysis above we propose an empirical framework
to estimate the movements of mortgage lending as follows
1 1 1Mortgage Pop Interest Rate Inflation NIM LTD House Prices it it it it i t i t it itf RR
The index of potential mortgagers is Pop which is estimated by the
percentage of urban population to total population in China It also refers to
the effect of urbanization and internal migration Inflation and House Prices
are macroeconomic factors which have potential impact on the mortgage
market NIM LTD represents the Net Interest Margins and Loan to Deposit
ratio These variables reflect the characteristics of individual banks Interest
Rate and RR the Required Reserves of banks are proxies of monetary policy
constraints
11
Previous research also indicates that House price is rather an endogenous
variable and driven by market factors including creditmortgage rationing
Inverted demand equation is then widely used to estimate the house prices
We employ a simplified version of the house price model which is proposed by
Muellbauer and Murphy (1997) 4

Where is the real user cost of housing services P is the real housing price

user cost into the housing stock function and involve the proxy of credit

Where HS eP P and I represent the housing stock expected appreciation

index of credit rationing Chinese housing financing system has not
4Dougherty and Order investigate the measurement of the housing cost through two alternative approaches

ratio
12
experienced significant change of this ratio However the change of Mortgage
can partially reflect the bankrsquos credit rationing The increase of mortgage loans
is associated with loose credit rationing and lower interest rate Therefore we
employ the change of mortgage to proxy the credit rationing index Taking
into account the estimation of mortgage lending we form a simultaneous
equation system as follows to estimate mortgage loans and endogenous
housing prices Considering the bank-level mortgage loan data panel data

32 Data description
Compared with developed countries Chinese mortgage market has a relative
short history and therefore limited data available In this paper an unbalanced
panel of annual mortgage loans of Commercial Banks is employed for the
analysis 6 Our sample consists of all State-Owned-Banks (SOBs)
Joint-Stock-Banks (JSBs) and major City-Commercial-Banks (CCBs) The sum of
mortgage credits in our sample covers more than 80 of total mortgage
outstanding which makes our sample highly representative Therefore fixed
effect model is more appropriate to control for the individual heterogeneity
6Since the financial reform in Chinese banking sector and new enforcement of information disclosure by China
Bank Regulatory Commission the mortgage data for some banks in early years is not available
13
Next we carefully select conventional explanatory variables for our empirical
analysis so as to ensure our estimation is robust to omitted variables The
variables included in the empirical framework are described in groups as
follows The macro data which is collected from the Peoplersquos Bank of China
and National Bureau of Statistics of China Mortgage loans bank specific
variables and house prices are collected from ALMANAC OF CHINAS FINANCE
AND BANKING which is the official publication of Peoplersquos Bank of China
Dependent variables
We are more interested in the movements of mortgage loan and housing
prices within a given year Therefore the change of mortgage loans of
individual banks and housing prices are employed as the dependent variable
In addition log transformation of mortgage loans is employed In order to
avoid heteroscedasticity
Macroeconomic explanatory variables
Although GDP is a popular variable to assess the macroeconomic situation
(Liang and Cao 2007 Davis and Zhu 2010) a large body of literature explores
the impact of disposable income as an alternative McQuinn and OrsquoReilly
(2007) Hill and Gan(2008) established the relationship between income and
house price from both theoretical and empirical sides7 Urban disposable
7Other existing researches also corroborate the potent influence of household income on the dynamics of
housing prices see Jud and Winkler 2002 Gimeno and Martinez-Carrascal 2006 Bourassa and Hoesli2006
14
Income is appropriate to analyse the movement of property prices We
employ the national average deposable income for SOBs and JSBs given their
nationwide business line and local average disposable income for CCBs
considering their local market focus In addition urban disposable income is
log transformed in order to avoid heteroscedasticity problem8
Urbanization is another factor of our interests that may drive the movement of
mortgage credits Over the past decade China has experienced a dramatic
process of industrialisation and urbanisation And Comparing with
industrialisation Chinas urbanisation developed more rapidly (Zheng et al
2007) More and more new immigrants moved into cities Taking into account
more potential home buyers a higher volume of mortgage loans is expected
We use the percentage of urban population to total population to capture the
effect of urbanisation
House stock refers to the number of existing residential units It is also
considered as the response to the land-use regulation through the elasticity of
new housing supply (Quigley and Raphael 2005) In our empirical analysis we
employ the number of house sales to proxy the housing stocks Furthermore
the expected rate of appreciation of house prices reflects consumersrsquo
Nevertheless some other literatures are not in favor of this point of viewGallin (2006) analyzes a panel of 95 US metropolitan areas over 23 years and does not find evidence of long-run relationship between the property prices and income in level This result is also proved by Tsatsaronis and Zhu (2004) who find little impact of household income on housing prices in their cross-country analysis 8No evidence of long-run relationship between the level of property prices and level of income is found by in
Gallin (2006) Therefore we intend to investigate this issue by involving log transformation of income (Ermini and Hendry2008)
15
purchase intention of houses In this empirical framework the ratio of house
price index to rental price index is used to proxy the house prices appreciation
And it is lagged one period to reduce simultaneity
Bank specific explanatory variables
The interest rate as an indicator of monetary policy is another widely
accepted explanatory variable9 It is calculated as the ratio of total interest
revenue over to interest bearing assets of individual banks A declining interest
rate environment contributes to the increasing demand for real estate and
housing investment (Greenand Shoven1986 Kearl1979 Tsatsaronis and Zhu
2004) In terms of Chinese housing market Liang and Cao (2007) suggest that
the property price movements have no sensitivity to the change of the real
interest rate By involving the rate of interest we reinvestigate to what extend
the raising interest rate can affect the mortgage credits and property prices
The required reserves are required to hold by commercial banks in the form of
deposits at the central bank Over the past decade along with the soaring
property prices and mortgage credit boom the central bank has raised the
required reserve ratio several times from 6 in 1999 to 20 in 2011 It is
viewed as another frequently used monetary policy other than the interest
9Hofmann (2003) concludes that real interest rate is more closely associated with property prices than with bank
lendingWolswijk (2006) and Eacutegertand Mihaljek (2007) confirm the negative effect of interest rate on houses prices in 15 EU countries and Eastern Europe
16
rate in China We explore in our paper whether the change of bank required
reserves has an impact on the movements of properties and mortgage credits
And we will compare the real effect of interest rate and required reserve ratio
We use one period lag transformation to reduce simultaneity
Loan_to_asset ratio is an important measure of balance sheet risk of individual
banks Since banks can not grant credit at all costs they need to conduct credit
audit and monitoring effectively in order to maintain low levels of
non-performing loans and increase margins (Abreuand Mendes 2001) In spite
of a positive relationship between Loan to deposit ratio and bank profitability
a high loan to deposit ratio is a warning sign of bankrsquos loan risk and then
discourage credit expansion In order to reduce simultaneity one period
lagged Loan_to_asset ratio is employed to capture the real effect of banksrsquo risk
taking behavior NIM is referred to as the net yield on interest-earning assets
and an indicator of profitability of a bankrsquos lending activities10 In addition
NIM is also a proxy of bank performance and profitability for Chinese banking
sector (Matthews 2009) We would like to test the favor of individual banks on
mortgage profits
Property prices as explanatory variables
The growth of four different property prices is employed in the empirical

framework They are condominium price the average real estate price and an
indicator of the whole property market residential price the indicator of solo
residential market high_grade houses price a measure of luxury and high-end
real estate market and economic houses price the price of affordable houses
for low-and-medium wage households Crone and Voith(1992) compare five
popular methods to estimate house price appreciation and conclude that the
mean sales price is least affected by the sample size and more accurate than
other estimating methods We aim to investigate the impact of different prices
on the change of mortgage separately The same as disposable income and
mortgage outstanding property prices are converted to logarithm form in
order to avoid heteroscedasticity problem Figure 4 illustrates the movements
of property prices in four separate real estate market
4 Results
41 Mortgage loans
The determinants mortgage lending are illustrated in table 3 from which we
test our hypotheses proposed in section 31
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
Our findings so far suggest that the volume of outstanding mortgage loans
increases with housing prices expect for the economic housing market which
is not surprising and in line with most recent evidence of developed countries
18
However we argue that the elasticity of condominium (and residential) price
to mortgage credits is around 17 which is much higher than that of other
countries 11 The condominium and residential prices illustrate a similar
impact on the mortgage lending It is simply because after the housing
reformation in 1998 all work units are not allowed to provide welfare houses
to employees As a result the fully market-oriented residential houses
contribute the majority of condominium supply in housing market and their
prices also follows similar movements On the other hand we find a contrary
result for economical house price which has a negative impact on mortgage
movements Since the economic houses focus on the market of medium amp
low income households and new migrants the increased price will weaken
the affordability of some potential buyer and vice versa The fallen price is
favored by more potential buyers most of whom need to rely on the
mortgages to finance their house purchasing
H2 Does the process of urbanisation has a positive effect on the mortgage
credits
The results of our estimation also support our second hypothesis Over the
past two decades China has been witnessing rapid urbanisation more and
more new immigrants choose to settle down in cities This massive internal
migration has brought about more potential home buyers and contributed to
11
The impact of housing price on mortgage credits is tested to be 05 for Ireland 062 for Spain and 075 for European Area (Fitzpatrick and McQuinn 2007 CarboValverde and Francisco Rodriguez 2010 Annett 2005)
19
the mortgage credit boom in China This impact of urbanisation is appreciable
which is reflected by the greater correlation coefficients of population than
other variables in our results Another interesting feature is that the change of
urban population has a more significant impact on the economic housing
market Since the purchasing power of new migrants is not as strong as city
natives the economical houses are of more concern to them and are more
sensitive to the change of urban population
In terms of monetary policies we found the interest rate is increasing with the
mortgage loans It tells us that the raising interest rate have little effect on
controlling the credit boom in China By contrast a negative correlation
between banksrsquo mortgage loans and required reserves for condominium and
residential markets is observed However the required reserves can neither
curb the credit boom for High_Grade and economic housing markets It
implies that although bankers were bracing for a slowdown in home loans
raising required reserves is not a good enough reason for them to curb their
loan to the High_Grade and economic houses mortgages which they view as
health asset in their portfolio Then we argue that compared with interest
tool the required reserve ratio is a relative effective instrument in controlling
the mortgage boom
20
CPI is the index of composite consumption goods12Increased CPI implies a
higher living expenditure which undermines the individualrsquos risk taking
intention of long-term mortgage loans And its impact on High_Grade and
economic housing markets is more significant In addition we found another
notable phenomenon is neither the net interest margin nor the loan to deposit
ratio affects the banksrsquo mortgage loans It tells us that the lending behavior of
Chinese commercial banks is more market-oriented rather not risk- or
profit-adjusted
42 House Prices
The determinants of housing price are illustrated in table 4 We can find that
the mortgage loan has a significant impact on the property prices The effect
on condominium and residential prices is positive which implies the
procyclical behavior of credits boom and condominium prices as a general
However the prices of High_Grade and Economical Houses have illustrated an
entirely different response to mortgage credits The economic houses in China
are also referred to as capped-price houses whose price is more
administrative interference rather not fully market-oriented And the market
of High_Grade properties features the high rigidity The movements of these
two special property markets cannot meet the boom of mortgage credits
12
According to the National Statistic Bureau of China property price is not calculated into CPI
21
Although the raising reserve ratio has little effect the interest rate moves
negative to the condominium prices and plays an active role in restraining the
housing prices We do not find significant impact of Housing Stock expected
appreciation rate of housing price and CPI on the movements of housing
prices
5 Conclusion
We use a bank level data set and panel data approach to gain insight in the
factors determining the growth of mortgage lending and housing prices Based
on Two-Stage Least SquaredInstrumental Variable approach the evidence of
relationship between house prices and mortgage credits is found We
document the positive impact of urbanization effect on the growth of
mortgage lending In terms of monetary policy we find negative effects of
required reserves on the change of mortgage credits and the interest rate on
property prices but not vice versa Our findings have important policy
implications and account for the existing monetary policies which are
implemented in China

Previous research also indicates that House price is rather an endogenous
variable and driven by market factors including creditmortgage rationing
Inverted demand equation is then widely used to estimate the house prices
We employ a simplified version of the house price model which is proposed by
Muellbauer and Murphy (1997) 4

Where is the real user cost of housing services P is the real housing price

index of credit rationing Chinese housing financing system has not

experienced significant change of this ratio However the change of Mortgage
can partially reflect the bankrsquos credit rationing The increase of mortgage loans
is associated with loose credit rationing and lower interest rate Therefore we
employ the change of mortgage to proxy the credit rationing index Taking
into account the estimation of mortgage lending we form a simultaneous
equation system as follows to estimate mortgage loans and endogenous
housing prices Considering the bank-level mortgage loan data panel data

32 Data description
Compared with developed countries Chinese mortgage market has a relative
short history and therefore limited data available In this paper an unbalanced
panel of annual mortgage loans of Commercial Banks is employed for the
analysis 6 Our sample consists of all State-Owned-Banks (SOBs)
Joint-Stock-Banks (JSBs) and major City-Commercial-Banks (CCBs) The sum of
mortgage credits in our sample covers more than 80 of total mortgage
outstanding which makes our sample highly representative Therefore fixed
effect model is more appropriate to control for the individual heterogeneity
6Since the financial reform in Chinese banking sector and new enforcement of information disclosure by China
Bank Regulatory Commission the mortgage data for some banks in early years is not available
13
Next we carefully select conventional explanatory variables for our empirical
analysis so as to ensure our estimation is robust to omitted variables The
variables included in the empirical framework are described in groups as
follows The macro data which is collected from the Peoplersquos Bank of China
and National Bureau of Statistics of China Mortgage loans bank specific
variables and house prices are collected from ALMANAC OF CHINAS FINANCE
AND BANKING which is the official publication of Peoplersquos Bank of China
Dependent variables
We are more interested in the movements of mortgage loan and housing
prices within a given year Therefore the change of mortgage loans of
individual banks and housing prices are employed as the dependent variable
In addition log transformation of mortgage loans is employed In order to
avoid heteroscedasticity
Macroeconomic explanatory variables
Although GDP is a popular variable to assess the macroeconomic situation
(Liang and Cao 2007 Davis and Zhu 2010) a large body of literature explores
the impact of disposable income as an alternative McQuinn and OrsquoReilly
(2007) Hill and Gan(2008) established the relationship between income and
house price from both theoretical and empirical sides7 Urban disposable
7Other existing researches also corroborate the potent influence of household income on the dynamics of
housing prices see Jud and Winkler 2002 Gimeno and Martinez-Carrascal 2006 Bourassa and Hoesli2006
14
Income is appropriate to analyse the movement of property prices We
employ the national average deposable income for SOBs and JSBs given their
nationwide business line and local average disposable income for CCBs
considering their local market focus In addition urban disposable income is
log transformed in order to avoid heteroscedasticity problem8
Urbanization is another factor of our interests that may drive the movement of
mortgage credits Over the past decade China has experienced a dramatic
process of industrialisation and urbanisation And Comparing with
industrialisation Chinas urbanisation developed more rapidly (Zheng et al
2007) More and more new immigrants moved into cities Taking into account
more potential home buyers a higher volume of mortgage loans is expected
We use the percentage of urban population to total population to capture the
effect of urbanisation
House stock refers to the number of existing residential units It is also
considered as the response to the land-use regulation through the elasticity of
new housing supply (Quigley and Raphael 2005) In our empirical analysis we
employ the number of house sales to proxy the housing stocks Furthermore
the expected rate of appreciation of house prices reflects consumersrsquo
Nevertheless some other literatures are not in favor of this point of viewGallin (2006) analyzes a panel of 95 US metropolitan areas over 23 years and does not find evidence of long-run relationship between the property prices and income in level This result is also proved by Tsatsaronis and Zhu (2004) who find little impact of household income on housing prices in their cross-country analysis 8No evidence of long-run relationship between the level of property prices and level of income is found by in
Gallin (2006) Therefore we intend to investigate this issue by involving log transformation of income (Ermini and Hendry2008)
15
purchase intention of houses In this empirical framework the ratio of house
price index to rental price index is used to proxy the house prices appreciation
And it is lagged one period to reduce simultaneity
Bank specific explanatory variables
The interest rate as an indicator of monetary policy is another widely
accepted explanatory variable9 It is calculated as the ratio of total interest
revenue over to interest bearing assets of individual banks A declining interest
rate environment contributes to the increasing demand for real estate and
housing investment (Greenand Shoven1986 Kearl1979 Tsatsaronis and Zhu
2004) In terms of Chinese housing market Liang and Cao (2007) suggest that
the property price movements have no sensitivity to the change of the real
interest rate By involving the rate of interest we reinvestigate to what extend
the raising interest rate can affect the mortgage credits and property prices
The required reserves are required to hold by commercial banks in the form of
deposits at the central bank Over the past decade along with the soaring
property prices and mortgage credit boom the central bank has raised the
required reserve ratio several times from 6 in 1999 to 20 in 2011 It is
viewed as another frequently used monetary policy other than the interest
9Hofmann (2003) concludes that real interest rate is more closely associated with property prices than with bank
lendingWolswijk (2006) and Eacutegertand Mihaljek (2007) confirm the negative effect of interest rate on houses prices in 15 EU countries and Eastern Europe
16
rate in China We explore in our paper whether the change of bank required
reserves has an impact on the movements of properties and mortgage credits
And we will compare the real effect of interest rate and required reserve ratio
We use one period lag transformation to reduce simultaneity
Loan_to_asset ratio is an important measure of balance sheet risk of individual
banks Since banks can not grant credit at all costs they need to conduct credit
audit and monitoring effectively in order to maintain low levels of
non-performing loans and increase margins (Abreuand Mendes 2001) In spite
of a positive relationship between Loan to deposit ratio and bank profitability
a high loan to deposit ratio is a warning sign of bankrsquos loan risk and then
discourage credit expansion In order to reduce simultaneity one period
lagged Loan_to_asset ratio is employed to capture the real effect of banksrsquo risk
taking behavior NIM is referred to as the net yield on interest-earning assets
and an indicator of profitability of a bankrsquos lending activities10 In addition
NIM is also a proxy of bank performance and profitability for Chinese banking
sector (Matthews 2009) We would like to test the favor of individual banks on
mortgage profits
Property prices as explanatory variables
The growth of four different property prices is employed in the empirical

framework They are condominium price the average real estate price and an
indicator of the whole property market residential price the indicator of solo
residential market high_grade houses price a measure of luxury and high-end
real estate market and economic houses price the price of affordable houses
for low-and-medium wage households Crone and Voith(1992) compare five
popular methods to estimate house price appreciation and conclude that the
mean sales price is least affected by the sample size and more accurate than
other estimating methods We aim to investigate the impact of different prices
on the change of mortgage separately The same as disposable income and
mortgage outstanding property prices are converted to logarithm form in
order to avoid heteroscedasticity problem Figure 4 illustrates the movements
of property prices in four separate real estate market
4 Results
41 Mortgage loans
The determinants mortgage lending are illustrated in table 3 from which we
test our hypotheses proposed in section 31
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
Our findings so far suggest that the volume of outstanding mortgage loans
increases with housing prices expect for the economic housing market which
is not surprising and in line with most recent evidence of developed countries
18
However we argue that the elasticity of condominium (and residential) price
to mortgage credits is around 17 which is much higher than that of other
countries 11 The condominium and residential prices illustrate a similar
impact on the mortgage lending It is simply because after the housing
reformation in 1998 all work units are not allowed to provide welfare houses
to employees As a result the fully market-oriented residential houses
contribute the majority of condominium supply in housing market and their
prices also follows similar movements On the other hand we find a contrary
result for economical house price which has a negative impact on mortgage
movements Since the economic houses focus on the market of medium amp
low income households and new migrants the increased price will weaken
the affordability of some potential buyer and vice versa The fallen price is
favored by more potential buyers most of whom need to rely on the
mortgages to finance their house purchasing
H2 Does the process of urbanisation has a positive effect on the mortgage
credits
The results of our estimation also support our second hypothesis Over the
past two decades China has been witnessing rapid urbanisation more and
more new immigrants choose to settle down in cities This massive internal
migration has brought about more potential home buyers and contributed to
11
The impact of housing price on mortgage credits is tested to be 05 for Ireland 062 for Spain and 075 for European Area (Fitzpatrick and McQuinn 2007 CarboValverde and Francisco Rodriguez 2010 Annett 2005)
19
the mortgage credit boom in China This impact of urbanisation is appreciable
which is reflected by the greater correlation coefficients of population than
other variables in our results Another interesting feature is that the change of
urban population has a more significant impact on the economic housing
market Since the purchasing power of new migrants is not as strong as city
natives the economical houses are of more concern to them and are more
sensitive to the change of urban population
In terms of monetary policies we found the interest rate is increasing with the
mortgage loans It tells us that the raising interest rate have little effect on
controlling the credit boom in China By contrast a negative correlation
between banksrsquo mortgage loans and required reserves for condominium and
residential markets is observed However the required reserves can neither
curb the credit boom for High_Grade and economic housing markets It
implies that although bankers were bracing for a slowdown in home loans
raising required reserves is not a good enough reason for them to curb their
loan to the High_Grade and economic houses mortgages which they view as
health asset in their portfolio Then we argue that compared with interest
tool the required reserve ratio is a relative effective instrument in controlling
the mortgage boom
20
CPI is the index of composite consumption goods12Increased CPI implies a
higher living expenditure which undermines the individualrsquos risk taking
intention of long-term mortgage loans And its impact on High_Grade and
economic housing markets is more significant In addition we found another
notable phenomenon is neither the net interest margin nor the loan to deposit
ratio affects the banksrsquo mortgage loans It tells us that the lending behavior of
Chinese commercial banks is more market-oriented rather not risk- or
profit-adjusted
42 House Prices
The determinants of housing price are illustrated in table 4 We can find that
the mortgage loan has a significant impact on the property prices The effect
on condominium and residential prices is positive which implies the
procyclical behavior of credits boom and condominium prices as a general
However the prices of High_Grade and Economical Houses have illustrated an
entirely different response to mortgage credits The economic houses in China
are also referred to as capped-price houses whose price is more
administrative interference rather not fully market-oriented And the market
of High_Grade properties features the high rigidity The movements of these
two special property markets cannot meet the boom of mortgage credits
12
According to the National Statistic Bureau of China property price is not calculated into CPI
21
Although the raising reserve ratio has little effect the interest rate moves
negative to the condominium prices and plays an active role in restraining the
housing prices We do not find significant impact of Housing Stock expected
appreciation rate of housing price and CPI on the movements of housing
prices
5 Conclusion
We use a bank level data set and panel data approach to gain insight in the
factors determining the growth of mortgage lending and housing prices Based
on Two-Stage Least SquaredInstrumental Variable approach the evidence of
relationship between house prices and mortgage credits is found We
document the positive impact of urbanization effect on the growth of
mortgage lending In terms of monetary policy we find negative effects of
required reserves on the change of mortgage credits and the interest rate on
property prices but not vice versa Our findings have important policy
implications and account for the existing monetary policies which are
implemented in China

experienced significant change of this ratio However the change of Mortgage
can partially reflect the bankrsquos credit rationing The increase of mortgage loans
is associated with loose credit rationing and lower interest rate Therefore we
employ the change of mortgage to proxy the credit rationing index Taking
into account the estimation of mortgage lending we form a simultaneous
equation system as follows to estimate mortgage loans and endogenous
housing prices Considering the bank-level mortgage loan data panel data
approach and two-stage least squaresInstrument variable method are

32 Data description
Compared with developed countries Chinese mortgage market has a relative
short history and therefore limited data available In this paper an unbalanced
panel of annual mortgage loans of Commercial Banks is employed for the
analysis 6 Our sample consists of all State-Owned-Banks (SOBs)
Joint-Stock-Banks (JSBs) and major City-Commercial-Banks (CCBs) The sum of
mortgage credits in our sample covers more than 80 of total mortgage
outstanding which makes our sample highly representative Therefore fixed
effect model is more appropriate to control for the individual heterogeneity
6Since the financial reform in Chinese banking sector and new enforcement of information disclosure by China
Bank Regulatory Commission the mortgage data for some banks in early years is not available
13
Next we carefully select conventional explanatory variables for our empirical
analysis so as to ensure our estimation is robust to omitted variables The
variables included in the empirical framework are described in groups as
follows The macro data which is collected from the Peoplersquos Bank of China
and National Bureau of Statistics of China Mortgage loans bank specific
variables and house prices are collected from ALMANAC OF CHINAS FINANCE
AND BANKING which is the official publication of Peoplersquos Bank of China
Dependent variables
We are more interested in the movements of mortgage loan and housing
prices within a given year Therefore the change of mortgage loans of
individual banks and housing prices are employed as the dependent variable
In addition log transformation of mortgage loans is employed In order to
avoid heteroscedasticity
Macroeconomic explanatory variables
Although GDP is a popular variable to assess the macroeconomic situation
(Liang and Cao 2007 Davis and Zhu 2010) a large body of literature explores
the impact of disposable income as an alternative McQuinn and OrsquoReilly
(2007) Hill and Gan(2008) established the relationship between income and
house price from both theoretical and empirical sides7 Urban disposable
7Other existing researches also corroborate the potent influence of household income on the dynamics of
housing prices see Jud and Winkler 2002 Gimeno and Martinez-Carrascal 2006 Bourassa and Hoesli2006
14
Income is appropriate to analyse the movement of property prices We
employ the national average deposable income for SOBs and JSBs given their
nationwide business line and local average disposable income for CCBs
considering their local market focus In addition urban disposable income is
log transformed in order to avoid heteroscedasticity problem8
Urbanization is another factor of our interests that may drive the movement of
mortgage credits Over the past decade China has experienced a dramatic
process of industrialisation and urbanisation And Comparing with
industrialisation Chinas urbanisation developed more rapidly (Zheng et al
2007) More and more new immigrants moved into cities Taking into account
more potential home buyers a higher volume of mortgage loans is expected
We use the percentage of urban population to total population to capture the
effect of urbanisation
House stock refers to the number of existing residential units It is also
considered as the response to the land-use regulation through the elasticity of
new housing supply (Quigley and Raphael 2005) In our empirical analysis we
employ the number of house sales to proxy the housing stocks Furthermore
the expected rate of appreciation of house prices reflects consumersrsquo
Nevertheless some other literatures are not in favor of this point of viewGallin (2006) analyzes a panel of 95 US metropolitan areas over 23 years and does not find evidence of long-run relationship between the property prices and income in level This result is also proved by Tsatsaronis and Zhu (2004) who find little impact of household income on housing prices in their cross-country analysis 8No evidence of long-run relationship between the level of property prices and level of income is found by in
Gallin (2006) Therefore we intend to investigate this issue by involving log transformation of income (Ermini and Hendry2008)
15
purchase intention of houses In this empirical framework the ratio of house
price index to rental price index is used to proxy the house prices appreciation
And it is lagged one period to reduce simultaneity
Bank specific explanatory variables
The interest rate as an indicator of monetary policy is another widely
accepted explanatory variable9 It is calculated as the ratio of total interest
revenue over to interest bearing assets of individual banks A declining interest
rate environment contributes to the increasing demand for real estate and
housing investment (Greenand Shoven1986 Kearl1979 Tsatsaronis and Zhu
2004) In terms of Chinese housing market Liang and Cao (2007) suggest that
the property price movements have no sensitivity to the change of the real
interest rate By involving the rate of interest we reinvestigate to what extend
the raising interest rate can affect the mortgage credits and property prices
The required reserves are required to hold by commercial banks in the form of
deposits at the central bank Over the past decade along with the soaring
property prices and mortgage credit boom the central bank has raised the
required reserve ratio several times from 6 in 1999 to 20 in 2011 It is
viewed as another frequently used monetary policy other than the interest
9Hofmann (2003) concludes that real interest rate is more closely associated with property prices than with bank
lendingWolswijk (2006) and Eacutegertand Mihaljek (2007) confirm the negative effect of interest rate on houses prices in 15 EU countries and Eastern Europe
16
rate in China We explore in our paper whether the change of bank required
reserves has an impact on the movements of properties and mortgage credits
And we will compare the real effect of interest rate and required reserve ratio
We use one period lag transformation to reduce simultaneity
Loan_to_asset ratio is an important measure of balance sheet risk of individual
banks Since banks can not grant credit at all costs they need to conduct credit
audit and monitoring effectively in order to maintain low levels of
non-performing loans and increase margins (Abreuand Mendes 2001) In spite
of a positive relationship between Loan to deposit ratio and bank profitability
a high loan to deposit ratio is a warning sign of bankrsquos loan risk and then
discourage credit expansion In order to reduce simultaneity one period
lagged Loan_to_asset ratio is employed to capture the real effect of banksrsquo risk
taking behavior NIM is referred to as the net yield on interest-earning assets
and an indicator of profitability of a bankrsquos lending activities10 In addition
NIM is also a proxy of bank performance and profitability for Chinese banking
sector (Matthews 2009) We would like to test the favor of individual banks on
mortgage profits
Property prices as explanatory variables
The growth of four different property prices is employed in the empirical

framework They are condominium price the average real estate price and an
indicator of the whole property market residential price the indicator of solo
residential market high_grade houses price a measure of luxury and high-end
real estate market and economic houses price the price of affordable houses
for low-and-medium wage households Crone and Voith(1992) compare five
popular methods to estimate house price appreciation and conclude that the
mean sales price is least affected by the sample size and more accurate than
other estimating methods We aim to investigate the impact of different prices
on the change of mortgage separately The same as disposable income and
mortgage outstanding property prices are converted to logarithm form in
order to avoid heteroscedasticity problem Figure 4 illustrates the movements
of property prices in four separate real estate market
4 Results
41 Mortgage loans
The determinants mortgage lending are illustrated in table 3 from which we
test our hypotheses proposed in section 31
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
Our findings so far suggest that the volume of outstanding mortgage loans
increases with housing prices expect for the economic housing market which
is not surprising and in line with most recent evidence of developed countries
18
However we argue that the elasticity of condominium (and residential) price
to mortgage credits is around 17 which is much higher than that of other
countries 11 The condominium and residential prices illustrate a similar
impact on the mortgage lending It is simply because after the housing
reformation in 1998 all work units are not allowed to provide welfare houses
to employees As a result the fully market-oriented residential houses
contribute the majority of condominium supply in housing market and their
prices also follows similar movements On the other hand we find a contrary
result for economical house price which has a negative impact on mortgage
movements Since the economic houses focus on the market of medium amp
low income households and new migrants the increased price will weaken
the affordability of some potential buyer and vice versa The fallen price is
favored by more potential buyers most of whom need to rely on the
mortgages to finance their house purchasing
H2 Does the process of urbanisation has a positive effect on the mortgage
credits
The results of our estimation also support our second hypothesis Over the
past two decades China has been witnessing rapid urbanisation more and
more new immigrants choose to settle down in cities This massive internal
migration has brought about more potential home buyers and contributed to
11
The impact of housing price on mortgage credits is tested to be 05 for Ireland 062 for Spain and 075 for European Area (Fitzpatrick and McQuinn 2007 CarboValverde and Francisco Rodriguez 2010 Annett 2005)
19
the mortgage credit boom in China This impact of urbanisation is appreciable
which is reflected by the greater correlation coefficients of population than
other variables in our results Another interesting feature is that the change of
urban population has a more significant impact on the economic housing
market Since the purchasing power of new migrants is not as strong as city
natives the economical houses are of more concern to them and are more
sensitive to the change of urban population
In terms of monetary policies we found the interest rate is increasing with the
mortgage loans It tells us that the raising interest rate have little effect on
controlling the credit boom in China By contrast a negative correlation
between banksrsquo mortgage loans and required reserves for condominium and
residential markets is observed However the required reserves can neither
curb the credit boom for High_Grade and economic housing markets It
implies that although bankers were bracing for a slowdown in home loans
raising required reserves is not a good enough reason for them to curb their
loan to the High_Grade and economic houses mortgages which they view as
health asset in their portfolio Then we argue that compared with interest
tool the required reserve ratio is a relative effective instrument in controlling
the mortgage boom
20
CPI is the index of composite consumption goods12Increased CPI implies a
higher living expenditure which undermines the individualrsquos risk taking
intention of long-term mortgage loans And its impact on High_Grade and
economic housing markets is more significant In addition we found another
notable phenomenon is neither the net interest margin nor the loan to deposit
ratio affects the banksrsquo mortgage loans It tells us that the lending behavior of
Chinese commercial banks is more market-oriented rather not risk- or
profit-adjusted
42 House Prices
The determinants of housing price are illustrated in table 4 We can find that
the mortgage loan has a significant impact on the property prices The effect
on condominium and residential prices is positive which implies the
procyclical behavior of credits boom and condominium prices as a general
However the prices of High_Grade and Economical Houses have illustrated an
entirely different response to mortgage credits The economic houses in China
are also referred to as capped-price houses whose price is more
administrative interference rather not fully market-oriented And the market
of High_Grade properties features the high rigidity The movements of these
two special property markets cannot meet the boom of mortgage credits
12
According to the National Statistic Bureau of China property price is not calculated into CPI
21
Although the raising reserve ratio has little effect the interest rate moves
negative to the condominium prices and plays an active role in restraining the
housing prices We do not find significant impact of Housing Stock expected
appreciation rate of housing price and CPI on the movements of housing
prices
5 Conclusion
We use a bank level data set and panel data approach to gain insight in the
factors determining the growth of mortgage lending and housing prices Based
on Two-Stage Least SquaredInstrumental Variable approach the evidence of
relationship between house prices and mortgage credits is found We
document the positive impact of urbanization effect on the growth of
mortgage lending In terms of monetary policy we find negative effects of
required reserves on the change of mortgage credits and the interest rate on
property prices but not vice versa Our findings have important policy
implications and account for the existing monetary policies which are
implemented in China

Next we carefully select conventional explanatory variables for our empirical
analysis so as to ensure our estimation is robust to omitted variables The
variables included in the empirical framework are described in groups as
follows The macro data which is collected from the Peoplersquos Bank of China
and National Bureau of Statistics of China Mortgage loans bank specific
variables and house prices are collected from ALMANAC OF CHINAS FINANCE
AND BANKING which is the official publication of Peoplersquos Bank of China
Dependent variables
We are more interested in the movements of mortgage loan and housing
prices within a given year Therefore the change of mortgage loans of
individual banks and housing prices are employed as the dependent variable
In addition log transformation of mortgage loans is employed In order to
avoid heteroscedasticity
Macroeconomic explanatory variables
Although GDP is a popular variable to assess the macroeconomic situation
(Liang and Cao 2007 Davis and Zhu 2010) a large body of literature explores
the impact of disposable income as an alternative McQuinn and OrsquoReilly
(2007) Hill and Gan(2008) established the relationship between income and
house price from both theoretical and empirical sides7 Urban disposable
7Other existing researches also corroborate the potent influence of household income on the dynamics of
housing prices see Jud and Winkler 2002 Gimeno and Martinez-Carrascal 2006 Bourassa and Hoesli2006
14
Income is appropriate to analyse the movement of property prices We
employ the national average deposable income for SOBs and JSBs given their
nationwide business line and local average disposable income for CCBs
considering their local market focus In addition urban disposable income is
log transformed in order to avoid heteroscedasticity problem8
Urbanization is another factor of our interests that may drive the movement of
mortgage credits Over the past decade China has experienced a dramatic
process of industrialisation and urbanisation And Comparing with
industrialisation Chinas urbanisation developed more rapidly (Zheng et al
2007) More and more new immigrants moved into cities Taking into account
more potential home buyers a higher volume of mortgage loans is expected
We use the percentage of urban population to total population to capture the
effect of urbanisation
House stock refers to the number of existing residential units It is also
considered as the response to the land-use regulation through the elasticity of
new housing supply (Quigley and Raphael 2005) In our empirical analysis we
employ the number of house sales to proxy the housing stocks Furthermore
the expected rate of appreciation of house prices reflects consumersrsquo
Nevertheless some other literatures are not in favor of this point of viewGallin (2006) analyzes a panel of 95 US metropolitan areas over 23 years and does not find evidence of long-run relationship between the property prices and income in level This result is also proved by Tsatsaronis and Zhu (2004) who find little impact of household income on housing prices in their cross-country analysis 8No evidence of long-run relationship between the level of property prices and level of income is found by in
Gallin (2006) Therefore we intend to investigate this issue by involving log transformation of income (Ermini and Hendry2008)
15
purchase intention of houses In this empirical framework the ratio of house
price index to rental price index is used to proxy the house prices appreciation
And it is lagged one period to reduce simultaneity
Bank specific explanatory variables
The interest rate as an indicator of monetary policy is another widely
accepted explanatory variable9 It is calculated as the ratio of total interest
revenue over to interest bearing assets of individual banks A declining interest
rate environment contributes to the increasing demand for real estate and
housing investment (Greenand Shoven1986 Kearl1979 Tsatsaronis and Zhu
2004) In terms of Chinese housing market Liang and Cao (2007) suggest that
the property price movements have no sensitivity to the change of the real
interest rate By involving the rate of interest we reinvestigate to what extend
the raising interest rate can affect the mortgage credits and property prices
The required reserves are required to hold by commercial banks in the form of
deposits at the central bank Over the past decade along with the soaring
property prices and mortgage credit boom the central bank has raised the
required reserve ratio several times from 6 in 1999 to 20 in 2011 It is
viewed as another frequently used monetary policy other than the interest
9Hofmann (2003) concludes that real interest rate is more closely associated with property prices than with bank
lendingWolswijk (2006) and Eacutegertand Mihaljek (2007) confirm the negative effect of interest rate on houses prices in 15 EU countries and Eastern Europe
16
rate in China We explore in our paper whether the change of bank required
reserves has an impact on the movements of properties and mortgage credits
And we will compare the real effect of interest rate and required reserve ratio
We use one period lag transformation to reduce simultaneity
Loan_to_asset ratio is an important measure of balance sheet risk of individual
banks Since banks can not grant credit at all costs they need to conduct credit
audit and monitoring effectively in order to maintain low levels of
non-performing loans and increase margins (Abreuand Mendes 2001) In spite
of a positive relationship between Loan to deposit ratio and bank profitability
a high loan to deposit ratio is a warning sign of bankrsquos loan risk and then
discourage credit expansion In order to reduce simultaneity one period
lagged Loan_to_asset ratio is employed to capture the real effect of banksrsquo risk
taking behavior NIM is referred to as the net yield on interest-earning assets
and an indicator of profitability of a bankrsquos lending activities10 In addition
NIM is also a proxy of bank performance and profitability for Chinese banking
sector (Matthews 2009) We would like to test the favor of individual banks on
mortgage profits
Property prices as explanatory variables
The growth of four different property prices is employed in the empirical

Hanweck and Ryu (2005) capture NIM dynamics in response to unanticipated credit and find negative relationship between NIM and expected credit loss

framework They are condominium price the average real estate price and an
indicator of the whole property market residential price the indicator of solo
residential market high_grade houses price a measure of luxury and high-end
real estate market and economic houses price the price of affordable houses
for low-and-medium wage households Crone and Voith(1992) compare five
popular methods to estimate house price appreciation and conclude that the
mean sales price is least affected by the sample size and more accurate than
other estimating methods We aim to investigate the impact of different prices
on the change of mortgage separately The same as disposable income and
mortgage outstanding property prices are converted to logarithm form in
order to avoid heteroscedasticity problem Figure 4 illustrates the movements
of property prices in four separate real estate market
4 Results
41 Mortgage loans
The determinants mortgage lending are illustrated in table 3 from which we
test our hypotheses proposed in section 31
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
Our findings so far suggest that the volume of outstanding mortgage loans
increases with housing prices expect for the economic housing market which
is not surprising and in line with most recent evidence of developed countries
18
However we argue that the elasticity of condominium (and residential) price
to mortgage credits is around 17 which is much higher than that of other
countries 11 The condominium and residential prices illustrate a similar
impact on the mortgage lending It is simply because after the housing
reformation in 1998 all work units are not allowed to provide welfare houses
to employees As a result the fully market-oriented residential houses
contribute the majority of condominium supply in housing market and their
prices also follows similar movements On the other hand we find a contrary
result for economical house price which has a negative impact on mortgage
movements Since the economic houses focus on the market of medium amp
low income households and new migrants the increased price will weaken
the affordability of some potential buyer and vice versa The fallen price is
favored by more potential buyers most of whom need to rely on the
mortgages to finance their house purchasing
H2 Does the process of urbanisation has a positive effect on the mortgage
credits
The results of our estimation also support our second hypothesis Over the
past two decades China has been witnessing rapid urbanisation more and
more new immigrants choose to settle down in cities This massive internal
migration has brought about more potential home buyers and contributed to
11
The impact of housing price on mortgage credits is tested to be 05 for Ireland 062 for Spain and 075 for European Area (Fitzpatrick and McQuinn 2007 CarboValverde and Francisco Rodriguez 2010 Annett 2005)
19
the mortgage credit boom in China This impact of urbanisation is appreciable
which is reflected by the greater correlation coefficients of population than
other variables in our results Another interesting feature is that the change of
urban population has a more significant impact on the economic housing
market Since the purchasing power of new migrants is not as strong as city
natives the economical houses are of more concern to them and are more
sensitive to the change of urban population
In terms of monetary policies we found the interest rate is increasing with the
mortgage loans It tells us that the raising interest rate have little effect on
controlling the credit boom in China By contrast a negative correlation
between banksrsquo mortgage loans and required reserves for condominium and
residential markets is observed However the required reserves can neither
curb the credit boom for High_Grade and economic housing markets It
implies that although bankers were bracing for a slowdown in home loans
raising required reserves is not a good enough reason for them to curb their
loan to the High_Grade and economic houses mortgages which they view as
health asset in their portfolio Then we argue that compared with interest
tool the required reserve ratio is a relative effective instrument in controlling
the mortgage boom
20
CPI is the index of composite consumption goods12Increased CPI implies a
higher living expenditure which undermines the individualrsquos risk taking
intention of long-term mortgage loans And its impact on High_Grade and
economic housing markets is more significant In addition we found another
notable phenomenon is neither the net interest margin nor the loan to deposit
ratio affects the banksrsquo mortgage loans It tells us that the lending behavior of
Chinese commercial banks is more market-oriented rather not risk- or
profit-adjusted
42 House Prices
The determinants of housing price are illustrated in table 4 We can find that
the mortgage loan has a significant impact on the property prices The effect
on condominium and residential prices is positive which implies the
procyclical behavior of credits boom and condominium prices as a general
However the prices of High_Grade and Economical Houses have illustrated an
entirely different response to mortgage credits The economic houses in China
are also referred to as capped-price houses whose price is more
administrative interference rather not fully market-oriented And the market
of High_Grade properties features the high rigidity The movements of these
two special property markets cannot meet the boom of mortgage credits
12
According to the National Statistic Bureau of China property price is not calculated into CPI
21
Although the raising reserve ratio has little effect the interest rate moves
negative to the condominium prices and plays an active role in restraining the
housing prices We do not find significant impact of Housing Stock expected
appreciation rate of housing price and CPI on the movements of housing
prices
5 Conclusion
We use a bank level data set and panel data approach to gain insight in the
factors determining the growth of mortgage lending and housing prices Based
on Two-Stage Least SquaredInstrumental Variable approach the evidence of
relationship between house prices and mortgage credits is found We
document the positive impact of urbanization effect on the growth of
mortgage lending In terms of monetary policy we find negative effects of
required reserves on the change of mortgage credits and the interest rate on
property prices but not vice versa Our findings have important policy
implications and account for the existing monetary policies which are
implemented in China

Income is appropriate to analyse the movement of property prices We
employ the national average deposable income for SOBs and JSBs given their
nationwide business line and local average disposable income for CCBs
considering their local market focus In addition urban disposable income is
log transformed in order to avoid heteroscedasticity problem8
Urbanization is another factor of our interests that may drive the movement of
mortgage credits Over the past decade China has experienced a dramatic
process of industrialisation and urbanisation And Comparing with
industrialisation Chinas urbanisation developed more rapidly (Zheng et al
2007) More and more new immigrants moved into cities Taking into account
more potential home buyers a higher volume of mortgage loans is expected
We use the percentage of urban population to total population to capture the
effect of urbanisation
House stock refers to the number of existing residential units It is also
considered as the response to the land-use regulation through the elasticity of
new housing supply (Quigley and Raphael 2005) In our empirical analysis we
employ the number of house sales to proxy the housing stocks Furthermore
the expected rate of appreciation of house prices reflects consumersrsquo
Nevertheless some other literatures are not in favor of this point of viewGallin (2006) analyzes a panel of 95 US metropolitan areas over 23 years and does not find evidence of long-run relationship between the property prices and income in level This result is also proved by Tsatsaronis and Zhu (2004) who find little impact of household income on housing prices in their cross-country analysis 8No evidence of long-run relationship between the level of property prices and level of income is found by in
Gallin (2006) Therefore we intend to investigate this issue by involving log transformation of income (Ermini and Hendry2008)
15
purchase intention of houses In this empirical framework the ratio of house
price index to rental price index is used to proxy the house prices appreciation
And it is lagged one period to reduce simultaneity
Bank specific explanatory variables
The interest rate as an indicator of monetary policy is another widely
accepted explanatory variable9 It is calculated as the ratio of total interest
revenue over to interest bearing assets of individual banks A declining interest
rate environment contributes to the increasing demand for real estate and
housing investment (Greenand Shoven1986 Kearl1979 Tsatsaronis and Zhu
2004) In terms of Chinese housing market Liang and Cao (2007) suggest that
the property price movements have no sensitivity to the change of the real
interest rate By involving the rate of interest we reinvestigate to what extend
the raising interest rate can affect the mortgage credits and property prices
The required reserves are required to hold by commercial banks in the form of
deposits at the central bank Over the past decade along with the soaring
property prices and mortgage credit boom the central bank has raised the
required reserve ratio several times from 6 in 1999 to 20 in 2011 It is
viewed as another frequently used monetary policy other than the interest
9Hofmann (2003) concludes that real interest rate is more closely associated with property prices than with bank
lendingWolswijk (2006) and Eacutegertand Mihaljek (2007) confirm the negative effect of interest rate on houses prices in 15 EU countries and Eastern Europe
16
rate in China We explore in our paper whether the change of bank required
reserves has an impact on the movements of properties and mortgage credits
And we will compare the real effect of interest rate and required reserve ratio
We use one period lag transformation to reduce simultaneity
Loan_to_asset ratio is an important measure of balance sheet risk of individual
banks Since banks can not grant credit at all costs they need to conduct credit
audit and monitoring effectively in order to maintain low levels of
non-performing loans and increase margins (Abreuand Mendes 2001) In spite
of a positive relationship between Loan to deposit ratio and bank profitability
a high loan to deposit ratio is a warning sign of bankrsquos loan risk and then
discourage credit expansion In order to reduce simultaneity one period
lagged Loan_to_asset ratio is employed to capture the real effect of banksrsquo risk
taking behavior NIM is referred to as the net yield on interest-earning assets
and an indicator of profitability of a bankrsquos lending activities10 In addition
NIM is also a proxy of bank performance and profitability for Chinese banking
sector (Matthews 2009) We would like to test the favor of individual banks on
mortgage profits
Property prices as explanatory variables
The growth of four different property prices is employed in the empirical

Hanweck and Ryu (2005) capture NIM dynamics in response to unanticipated credit and find negative relationship between NIM and expected credit loss

framework They are condominium price the average real estate price and an
indicator of the whole property market residential price the indicator of solo
residential market high_grade houses price a measure of luxury and high-end
real estate market and economic houses price the price of affordable houses
for low-and-medium wage households Crone and Voith(1992) compare five
popular methods to estimate house price appreciation and conclude that the
mean sales price is least affected by the sample size and more accurate than
other estimating methods We aim to investigate the impact of different prices
on the change of mortgage separately The same as disposable income and
mortgage outstanding property prices are converted to logarithm form in
order to avoid heteroscedasticity problem Figure 4 illustrates the movements
of property prices in four separate real estate market
4 Results
41 Mortgage loans
The determinants mortgage lending are illustrated in table 3 from which we
test our hypotheses proposed in section 31
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
Our findings so far suggest that the volume of outstanding mortgage loans
increases with housing prices expect for the economic housing market which
is not surprising and in line with most recent evidence of developed countries
18
However we argue that the elasticity of condominium (and residential) price
to mortgage credits is around 17 which is much higher than that of other
countries 11 The condominium and residential prices illustrate a similar
impact on the mortgage lending It is simply because after the housing
reformation in 1998 all work units are not allowed to provide welfare houses
to employees As a result the fully market-oriented residential houses
contribute the majority of condominium supply in housing market and their
prices also follows similar movements On the other hand we find a contrary
result for economical house price which has a negative impact on mortgage
movements Since the economic houses focus on the market of medium amp
low income households and new migrants the increased price will weaken
the affordability of some potential buyer and vice versa The fallen price is
favored by more potential buyers most of whom need to rely on the
mortgages to finance their house purchasing
H2 Does the process of urbanisation has a positive effect on the mortgage
credits
The results of our estimation also support our second hypothesis Over the
past two decades China has been witnessing rapid urbanisation more and
more new immigrants choose to settle down in cities This massive internal
migration has brought about more potential home buyers and contributed to
11
The impact of housing price on mortgage credits is tested to be 05 for Ireland 062 for Spain and 075 for European Area (Fitzpatrick and McQuinn 2007 CarboValverde and Francisco Rodriguez 2010 Annett 2005)
19
the mortgage credit boom in China This impact of urbanisation is appreciable
which is reflected by the greater correlation coefficients of population than
other variables in our results Another interesting feature is that the change of
urban population has a more significant impact on the economic housing
market Since the purchasing power of new migrants is not as strong as city
natives the economical houses are of more concern to them and are more
sensitive to the change of urban population
In terms of monetary policies we found the interest rate is increasing with the
mortgage loans It tells us that the raising interest rate have little effect on
controlling the credit boom in China By contrast a negative correlation
between banksrsquo mortgage loans and required reserves for condominium and
residential markets is observed However the required reserves can neither
curb the credit boom for High_Grade and economic housing markets It
implies that although bankers were bracing for a slowdown in home loans
raising required reserves is not a good enough reason for them to curb their
loan to the High_Grade and economic houses mortgages which they view as
health asset in their portfolio Then we argue that compared with interest
tool the required reserve ratio is a relative effective instrument in controlling
the mortgage boom
20
CPI is the index of composite consumption goods12Increased CPI implies a
higher living expenditure which undermines the individualrsquos risk taking
intention of long-term mortgage loans And its impact on High_Grade and
economic housing markets is more significant In addition we found another
notable phenomenon is neither the net interest margin nor the loan to deposit
ratio affects the banksrsquo mortgage loans It tells us that the lending behavior of
Chinese commercial banks is more market-oriented rather not risk- or
profit-adjusted
42 House Prices
The determinants of housing price are illustrated in table 4 We can find that
the mortgage loan has a significant impact on the property prices The effect
on condominium and residential prices is positive which implies the
procyclical behavior of credits boom and condominium prices as a general
However the prices of High_Grade and Economical Houses have illustrated an
entirely different response to mortgage credits The economic houses in China
are also referred to as capped-price houses whose price is more
administrative interference rather not fully market-oriented And the market
of High_Grade properties features the high rigidity The movements of these
two special property markets cannot meet the boom of mortgage credits
12
According to the National Statistic Bureau of China property price is not calculated into CPI
21
Although the raising reserve ratio has little effect the interest rate moves
negative to the condominium prices and plays an active role in restraining the
housing prices We do not find significant impact of Housing Stock expected
appreciation rate of housing price and CPI on the movements of housing
prices
5 Conclusion
We use a bank level data set and panel data approach to gain insight in the
factors determining the growth of mortgage lending and housing prices Based
on Two-Stage Least SquaredInstrumental Variable approach the evidence of
relationship between house prices and mortgage credits is found We
document the positive impact of urbanization effect on the growth of
mortgage lending In terms of monetary policy we find negative effects of
required reserves on the change of mortgage credits and the interest rate on
property prices but not vice versa Our findings have important policy
implications and account for the existing monetary policies which are
implemented in China

4 Results
41 Mortgage loans
The determinants mortgage lending are illustrated in table 3 from which we
test our hypotheses proposed in section 31
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
Our findings so far suggest that the volume of outstanding mortgage loans
increases with housing prices expect for the economic housing market which
is not surprising and in line with most recent evidence of developed countries
18
However we argue that the elasticity of condominium (and residential) price
to mortgage credits is around 17 which is much higher than that of other
countries 11 The condominium and residential prices illustrate a similar
impact on the mortgage lending It is simply because after the housing
reformation in 1998 all work units are not allowed to provide welfare houses
to employees As a result the fully market-oriented residential houses
contribute the majority of condominium supply in housing market and their
prices also follows similar movements On the other hand we find a contrary
result for economical house price which has a negative impact on mortgage
movements Since the economic houses focus on the market of medium amp
low income households and new migrants the increased price will weaken
the affordability of some potential buyer and vice versa The fallen price is
favored by more potential buyers most of whom need to rely on the
mortgages to finance their house purchasing
H2 Does the process of urbanisation has a positive effect on the mortgage
credits
The results of our estimation also support our second hypothesis Over the
past two decades China has been witnessing rapid urbanisation more and
more new immigrants choose to settle down in cities This massive internal
migration has brought about more potential home buyers and contributed to
11
The impact of housing price on mortgage credits is tested to be 05 for Ireland 062 for Spain and 075 for European Area (Fitzpatrick and McQuinn 2007 CarboValverde and Francisco Rodriguez 2010 Annett 2005)
19
the mortgage credit boom in China This impact of urbanisation is appreciable
which is reflected by the greater correlation coefficients of population than
other variables in our results Another interesting feature is that the change of
urban population has a more significant impact on the economic housing
market Since the purchasing power of new migrants is not as strong as city
natives the economical houses are of more concern to them and are more
sensitive to the change of urban population
In terms of monetary policies we found the interest rate is increasing with the
mortgage loans It tells us that the raising interest rate have little effect on
controlling the credit boom in China By contrast a negative correlation
between banksrsquo mortgage loans and required reserves for condominium and
residential markets is observed However the required reserves can neither
curb the credit boom for High_Grade and economic housing markets It
implies that although bankers were bracing for a slowdown in home loans
raising required reserves is not a good enough reason for them to curb their
loan to the High_Grade and economic houses mortgages which they view as
health asset in their portfolio Then we argue that compared with interest
tool the required reserve ratio is a relative effective instrument in controlling
the mortgage boom
20
CPI is the index of composite consumption goods12Increased CPI implies a
higher living expenditure which undermines the individualrsquos risk taking
intention of long-term mortgage loans And its impact on High_Grade and
economic housing markets is more significant In addition we found another
notable phenomenon is neither the net interest margin nor the loan to deposit
ratio affects the banksrsquo mortgage loans It tells us that the lending behavior of
Chinese commercial banks is more market-oriented rather not risk- or
profit-adjusted
42 House Prices
The determinants of housing price are illustrated in table 4 We can find that
the mortgage loan has a significant impact on the property prices The effect
on condominium and residential prices is positive which implies the
procyclical behavior of credits boom and condominium prices as a general
However the prices of High_Grade and Economical Houses have illustrated an
entirely different response to mortgage credits The economic houses in China
are also referred to as capped-price houses whose price is more
administrative interference rather not fully market-oriented And the market
of High_Grade properties features the high rigidity The movements of these
two special property markets cannot meet the boom of mortgage credits
12
According to the National Statistic Bureau of China property price is not calculated into CPI
21
Although the raising reserve ratio has little effect the interest rate moves
negative to the condominium prices and plays an active role in restraining the
housing prices We do not find significant impact of Housing Stock expected
appreciation rate of housing price and CPI on the movements of housing
prices
5 Conclusion
We use a bank level data set and panel data approach to gain insight in the
factors determining the growth of mortgage lending and housing prices Based
on Two-Stage Least SquaredInstrumental Variable approach the evidence of
relationship between house prices and mortgage credits is found We
document the positive impact of urbanization effect on the growth of
mortgage lending In terms of monetary policy we find negative effects of
required reserves on the change of mortgage credits and the interest rate on
property prices but not vice versa Our findings have important policy
implications and account for the existing monetary policies which are
implemented in China

rate in China We explore in our paper whether the change of bank required
reserves has an impact on the movements of properties and mortgage credits
And we will compare the real effect of interest rate and required reserve ratio
We use one period lag transformation to reduce simultaneity
Loan_to_asset ratio is an important measure of balance sheet risk of individual
banks Since banks can not grant credit at all costs they need to conduct credit
audit and monitoring effectively in order to maintain low levels of
non-performing loans and increase margins (Abreuand Mendes 2001) In spite
of a positive relationship between Loan to deposit ratio and bank profitability
a high loan to deposit ratio is a warning sign of bankrsquos loan risk and then
discourage credit expansion In order to reduce simultaneity one period
lagged Loan_to_asset ratio is employed to capture the real effect of banksrsquo risk
taking behavior NIM is referred to as the net yield on interest-earning assets
and an indicator of profitability of a bankrsquos lending activities10 In addition

framework They are condominium price the average real estate price and an
indicator of the whole property market residential price the indicator of solo
residential market high_grade houses price a measure of luxury and high-end
real estate market and economic houses price the price of affordable houses
for low-and-medium wage households Crone and Voith(1992) compare five
popular methods to estimate house price appreciation and conclude that the
mean sales price is least affected by the sample size and more accurate than
other estimating methods We aim to investigate the impact of different prices
on the change of mortgage separately The same as disposable income and
mortgage outstanding property prices are converted to logarithm form in
order to avoid heteroscedasticity problem Figure 4 illustrates the movements
of property prices in four separate real estate market
4 Results
41 Mortgage loans
The determinants mortgage lending are illustrated in table 3 from which we
test our hypotheses proposed in section 31
H1 Do the mortgage credits and housing prices tend to be closely associated
with each other
Our findings so far suggest that the volume of outstanding mortgage loans
increases with housing prices expect for the economic housing market which
is not surprising and in line with most recent evidence of developed countries
18
However we argue that the elasticity of condominium (and residential) price
to mortgage credits is around 17 which is much higher than that of other
countries 11 The condominium and residential prices illustrate a similar
impact on the mortgage lending It is simply because after the housing
reformation in 1998 all work units are not allowed to provide welfare houses
to employees As a result the fully market-oriented residential houses
contribute the majority of condominium supply in housing market and their
prices also follows similar movements On the other hand we find a contrary
result for economical house price which has a negative impact on mortgage
movements Since the economic houses focus on the market of medium amp
low income households and new migrants the increased price will weaken
the affordability of some potential buyer and vice versa The fallen price is
favored by more potential buyers most of whom need to rely on the
mortgages to finance their house purchasing
H2 Does the process of urbanisation has a positive effect on the mortgage
credits
The results of our estimation also support our second hypothesis Over the
past two decades China has been witnessing rapid urbanisation more and
more new immigrants choose to settle down in cities This massive internal
migration has brought about more potential home buyers and contributed to
11
The impact of housing price on mortgage credits is tested to be 05 for Ireland 062 for Spain and 075 for European Area (Fitzpatrick and McQuinn 2007 CarboValverde and Francisco Rodriguez 2010 Annett 2005)
19
the mortgage credit boom in China This impact of urbanisation is appreciable
which is reflected by the greater correlation coefficients of population than
other variables in our results Another interesting feature is that the change of
urban population has a more significant impact on the economic housing
market Since the purchasing power of new migrants is not as strong as city
natives the economical houses are of more concern to them and are more
sensitive to the change of urban population
In terms of monetary policies we found the interest rate is increasing with the
mortgage loans It tells us that the raising interest rate have little effect on
controlling the credit boom in China By contrast a negative correlation
between banksrsquo mortgage loans and required reserves for condominium and
residential markets is observed However the required reserves can neither
curb the credit boom for High_Grade and economic housing markets It
implies that although bankers were bracing for a slowdown in home loans
raising required reserves is not a good enough reason for them to curb their
loan to the High_Grade and economic houses mortgages which they view as
health asset in their portfolio Then we argue that compared with interest
tool the required reserve ratio is a relative effective instrument in controlling
the mortgage boom
20
CPI is the index of composite consumption goods12Increased CPI implies a
higher living expenditure which undermines the individualrsquos risk taking
intention of long-term mortgage loans And its impact on High_Grade and
economic housing markets is more significant In addition we found another
notable phenomenon is neither the net interest margin nor the loan to deposit
ratio affects the banksrsquo mortgage loans It tells us that the lending behavior of
Chinese commercial banks is more market-oriented rather not risk- or
profit-adjusted
42 House Prices
The determinants of housing price are illustrated in table 4 We can find that
the mortgage loan has a significant impact on the property prices The effect
on condominium and residential prices is positive which implies the
procyclical behavior of credits boom and condominium prices as a general
However the prices of High_Grade and Economical Houses have illustrated an
entirely different response to mortgage credits The economic houses in China
are also referred to as capped-price houses whose price is more
administrative interference rather not fully market-oriented And the market
of High_Grade properties features the high rigidity The movements of these
two special property markets cannot meet the boom of mortgage credits
12
According to the National Statistic Bureau of China property price is not calculated into CPI
21
Although the raising reserve ratio has little effect the interest rate moves
negative to the condominium prices and plays an active role in restraining the
housing prices We do not find significant impact of Housing Stock expected
appreciation rate of housing price and CPI on the movements of housing
prices
5 Conclusion
We use a bank level data set and panel data approach to gain insight in the
factors determining the growth of mortgage lending and housing prices Based
on Two-Stage Least SquaredInstrumental Variable approach the evidence of
relationship between house prices and mortgage credits is found We
document the positive impact of urbanization effect on the growth of
mortgage lending In terms of monetary policy we find negative effects of
required reserves on the change of mortgage credits and the interest rate on
property prices but not vice versa Our findings have important policy
implications and account for the existing monetary policies which are
implemented in China

However we argue that the elasticity of condominium (and residential) price
to mortgage credits is around 17 which is much higher than that of other
countries 11 The condominium and residential prices illustrate a similar
impact on the mortgage lending It is simply because after the housing
reformation in 1998 all work units are not allowed to provide welfare houses
to employees As a result the fully market-oriented residential houses
contribute the majority of condominium supply in housing market and their
prices also follows similar movements On the other hand we find a contrary
result for economical house price which has a negative impact on mortgage
movements Since the economic houses focus on the market of medium amp
low income households and new migrants the increased price will weaken
the affordability of some potential buyer and vice versa The fallen price is
favored by more potential buyers most of whom need to rely on the
mortgages to finance their house purchasing
H2 Does the process of urbanisation has a positive effect on the mortgage
credits
The results of our estimation also support our second hypothesis Over the
past two decades China has been witnessing rapid urbanisation more and
more new immigrants choose to settle down in cities This massive internal
migration has brought about more potential home buyers and contributed to
11
The impact of housing price on mortgage credits is tested to be 05 for Ireland 062 for Spain and 075 for European Area (Fitzpatrick and McQuinn 2007 CarboValverde and Francisco Rodriguez 2010 Annett 2005)

the mortgage credit boom in China This impact of urbanisation is appreciable
which is reflected by the greater correlation coefficients of population than
other variables in our results Another interesting feature is that the change of
urban population has a more significant impact on the economic housing
market Since the purchasing power of new migrants is not as strong as city
natives the economical houses are of more concern to them and are more
sensitive to the change of urban population
In terms of monetary policies we found the interest rate is increasing with the
mortgage loans It tells us that the raising interest rate have little effect on
controlling the credit boom in China By contrast a negative correlation
between banksrsquo mortgage loans and required reserves for condominium and
residential markets is observed However the required reserves can neither
curb the credit boom for High_Grade and economic housing markets It
implies that although bankers were bracing for a slowdown in home loans
raising required reserves is not a good enough reason for them to curb their
loan to the High_Grade and economic houses mortgages which they view as
health asset in their portfolio Then we argue that compared with interest
tool the required reserve ratio is a relative effective instrument in controlling
the mortgage boom
20
CPI is the index of composite consumption goods12Increased CPI implies a
higher living expenditure which undermines the individualrsquos risk taking
intention of long-term mortgage loans And its impact on High_Grade and
economic housing markets is more significant In addition we found another
notable phenomenon is neither the net interest margin nor the loan to deposit
ratio affects the banksrsquo mortgage loans It tells us that the lending behavior of
Chinese commercial banks is more market-oriented rather not risk- or
profit-adjusted
42 House Prices
The determinants of housing price are illustrated in table 4 We can find that
the mortgage loan has a significant impact on the property prices The effect
on condominium and residential prices is positive which implies the
procyclical behavior of credits boom and condominium prices as a general
However the prices of High_Grade and Economical Houses have illustrated an
entirely different response to mortgage credits The economic houses in China
are also referred to as capped-price houses whose price is more
administrative interference rather not fully market-oriented And the market
of High_Grade properties features the high rigidity The movements of these
two special property markets cannot meet the boom of mortgage credits
12
According to the National Statistic Bureau of China property price is not calculated into CPI
21
Although the raising reserve ratio has little effect the interest rate moves
negative to the condominium prices and plays an active role in restraining the
housing prices We do not find significant impact of Housing Stock expected
appreciation rate of housing price and CPI on the movements of housing
prices
5 Conclusion
We use a bank level data set and panel data approach to gain insight in the
factors determining the growth of mortgage lending and housing prices Based
on Two-Stage Least SquaredInstrumental Variable approach the evidence of
relationship between house prices and mortgage credits is found We
document the positive impact of urbanization effect on the growth of
mortgage lending In terms of monetary policy we find negative effects of
required reserves on the change of mortgage credits and the interest rate on
property prices but not vice versa Our findings have important policy
implications and account for the existing monetary policies which are
implemented in China

CPI is the index of composite consumption goods12Increased CPI implies a
higher living expenditure which undermines the individualrsquos risk taking
intention of long-term mortgage loans And its impact on High_Grade and
economic housing markets is more significant In addition we found another
notable phenomenon is neither the net interest margin nor the loan to deposit
ratio affects the banksrsquo mortgage loans It tells us that the lending behavior of
Chinese commercial banks is more market-oriented rather not risk- or
profit-adjusted
42 House Prices
The determinants of housing price are illustrated in table 4 We can find that
the mortgage loan has a significant impact on the property prices The effect
on condominium and residential prices is positive which implies the
procyclical behavior of credits boom and condominium prices as a general
However the prices of High_Grade and Economical Houses have illustrated an
entirely different response to mortgage credits The economic houses in China
are also referred to as capped-price houses whose price is more
administrative interference rather not fully market-oriented And the market
of High_Grade properties features the high rigidity The movements of these
two special property markets cannot meet the boom of mortgage credits
12
According to the National Statistic Bureau of China property price is not calculated into CPI
21
Although the raising reserve ratio has little effect the interest rate moves
negative to the condominium prices and plays an active role in restraining the
housing prices We do not find significant impact of Housing Stock expected
appreciation rate of housing price and CPI on the movements of housing
prices
5 Conclusion
We use a bank level data set and panel data approach to gain insight in the
factors determining the growth of mortgage lending and housing prices Based
on Two-Stage Least SquaredInstrumental Variable approach the evidence of
relationship between house prices and mortgage credits is found We
document the positive impact of urbanization effect on the growth of
mortgage lending In terms of monetary policy we find negative effects of
required reserves on the change of mortgage credits and the interest rate on
property prices but not vice versa Our findings have important policy
implications and account for the existing monetary policies which are
implemented in China
