Abstract
This paper examines the cross-sectional relation between corporate governance and firm liquidity in
the Chinese stock market. Each year we construct a measure of overall quality of governance based
on publicly available information for each firm listed on the Shanghai Stock Exchange (SHSE) and
the Shenzhen Stock Exchange (SZSE) over the 1999-2004 interval. After accounting for other
liquidity-related factors, we present strong evidence that the level of corporate governance is
positively related to firm liquidity. An increase of 1% in corporate governance index (total 100%) is
on average associated with 1.2% increase in a firm‟s annual turnover ratio over the subsequent year.
Results from examinations of subindices of corporate governance provide further support for the
positive governance-liquidity relation. These findings have important implications for academics to
investigate the value of enhancing corporate governance, and for regulators to promote corporate
governance reform.

1. Introduction
There is substantial evidence that corporate governance rules or governance practices at country
levels are associated with the development and strength of financial markets, namely, higher levels of
governance are related to larger securities markets, more frequent IPOs, lower costs of external
finance, and higher value of minority shares (La Porta et al., 1997, 1998, 2000, 2002; Berkowitz et al.,
2001; Lambardo and Pagano, 2000; Gompers et al., 2002; and Beck et al., 2003). Researchers have
also shown that within-country variations in corporate governance practices affect firm value. Black
(2001) finds a strong correlation between a governance index and share prices of Russian firms.
Durnev and Kim (2003) document that high scores of Credit Lyonnais Securities Asia (CLSA)
corporate governance index and the S&P disclosure index predict higher Tobin‟s Q for a sample of
859 large firms in 27 countries. Gompers et al. (2003) use the differences in takeover defense
provisions to create a corporate governance index for U.S firms, and find that firms with stronger
shareholder rights have better operating performance, higher market valuation, higher sales growth,
and are more likely to make acquisitions. Black et al. (2005) report that corporate governance is an
important factor explaining the variations in market value of Korean public companies. Cheung et al.
(2008) document a positive relation between the corporate governance index and various measures of
firm performance in the Hong Kong stock market.
Corporate governance aims at resolving conflict of interests between managers and shareholders
and between large shareholders and minority shareholders, and thus mitigates agency costs. Financial
transparency, operational transparency, and information disclosure are extremely important elements
of corporate governance. Firms that adopt poor corporate governance practices are usually associated
with a low level of financial and operational transparency, and low quality of information disclosure,
3
which implies great information asymmetry and low firm liquidity. Botosan (1997) shows that an
increase of a firm‟s disclosure reduces information asymmetry between shareholders and managers.
Lang and Lundholm (1999) report that a higher level of transparency and higher quality of disclosure
are associated with lower information risk and smaller transaction costs. As a result, liquidity
providers, such as market makers and outsider investors (in electronic trading system), will take
actions to protect themselves by enlarging bid-ask spreads or limiting market participation. Several
studies have also documented that some particular aspects of corporate governance affect firm
liquidity. For example, Jain (2001) shows that bid-ask spreads are narrower in countries with better
shareholders‟ rights. Bacidore and Sofianos (2002) document that firms listed on the New York Stock
Exchange that are based in the U.S. exhibit higher liquidity than those based in outside the U.S. Attig
et al. (2003) find that deviations of ownership from control increase bid-ask spreads in the Canadian
stock market. Brockman and Chung (2003) show that liquidity costs are lower for the Hong
Kong-based blue chips than for the China-based firms, suggesting that better investor protection (for
blue chips in Hong Kong) is associated with higher liquidity. More recently, Chung et al. (2010)
examine the relation between transparency-related governance attributes and liquidity in the U.S.
stock market, and find that firms with better governance structure exhibit narrower quoted and
effective spreads, smaller price impact of trades, and lower probability of information-based trading.
However, there has been no study examining explicitly the relation between overall quality of
corporate governance and firm liquidity.
This paper contributes to the literature by analyzing the cross-sectional relation between overall
corporate governance and firm liquidity using individual firm data from the Shanghai Stock
Exchange (SHSE) and the Shenzhen Stock Exchange (SZSE). Based on the theoretical predictions
4
and empirical evidence in the finance and economics literature, we construct a measure to evaluate
the overall quality of governance using governance practices-related information of listed companies
disclosed in their annual financial reports. After accounting for other liquidity related factors, we
report strong evidence that the level of corporate governance index is positively related to firm
liquidity in the subsequent year. An increase of 1% in corporate governance index (total 100%) is on
average associated with 1.2% increase of a firm‟s annual turnover ratio over the subsequent year. We
also construct two subindices of corporate governance based on governance attributes in board
structure and ownership structure respectively, and show that both the subindices of corporate
governance are positively related to firm liquidity.
The positive relation between corporate governance and firm liquidity has important
implications for academics. Empirical studies that utilized various corporate governance indices have
shown that corporate governance is positively associated with firm value or stock returns (Gompers
et al., 2003; Bebchuk et al., 2004). Studies of asset prices and liquidity document a negative relation
between stock return and liquidity (Amihud and Mendelson, 1986; Amihud, 2002). The negative
return-liquidity relation implies that firms with higher liquidity have lower costs of capital, and as a
consequence, higher firm value, lower required returns from investors. Therefore, our results suggest
that the value creation role of corporate governance reported in the extant literature tends to be
underestimated. Our empirical findings also have implications for market regulators to promote
corporate governance reform. A common concern is that corporate governance reforms may dampen
market liquidity (Bhide, 1993). Our findings imply that maintaining good corporate governance is
beneficial for firms in terms of both value creation and liquidity.
The remainder of this paper is organized as follows. In Section 2, we lay out the hypothesis
5
relating corporate governance to liquidity. Section 3 describes the data and methodology. Section 4
presents the empirical results. The final section concludes.
2. Hypothesis Development
Extant researches have shown that firms adopting poor corporate governance practices are
usually associated with a low level of financial transparency and operational efficiency, and low
quality of information disclosure. Therefore, poor corporate governance practices intensify
information asymmetry problems between insiders and investors, increase the probability of trading
against informed traders, and increase the likelihood of wealth expropriation of minority shareholders
by controlling shareholders.
Leuz et al. (2003) show that governance provisions improve financial transparency by mitigating
management‟s incentive and ability to distort information disclosure. Ajinkya et al. (2005) report that
more effective boards enhance the quality and frequency of information released by management,
and therefore, companies with more effective boards issue more frequent and accurate earnings
forecasts. Bebchuk et al. (2005) show that governance provisions help to protect shareholder interests
and limit the extent to which management expropriates firm value through shirking, empire building,
and perquisites. Diamond (1985) demonstrates that increased disclosure reduces both the precision of
private information and the incentive for private information search. A decrease in information
asymmetry between management and investors tends to reduce investors‟ incentive to acquire private
information, resulting in less heterogeneity in investor beliefs and smaller speculative position of
informed traders. In such an environment, liquidity providers or uninformed traders face smaller
adverse selection problems in the stocks, resulting in narrower bid-ask spreads and greater trading
6
activity. Therefore, extant literature suggests that poor corporate governance is associated with a low
level of financial and operational transparency, and thus impairs stock market liquidity.
Several studies have examined the impact of cross-country differences in legal and regulatory
environments on stock market liquidity. Jain (2001) investigates the relation between institutional
design and firm liquidity. Although his study focuses primarily on variables under the control of
exchange (i.e., the market making system), one relevant result is that bid-ask spreads are narrower in
countries with better shareholder rights. Bacidore and Sofianos (2002) show that firms listed on the
New York Stock Exchange that are based in the U.S. exhibit higher liquidity than those based in
outside the U.S. Brockman and Chung (2003) examine the impact of investor protection on firm
liquidity using a sample of blue-chips and China-based firms traded on the Stock Exchange of Hong
Kong, and show that liquidity costs are lower for the Hong Kong-based blue chips than for the
China-based firms. They conclude that better investor protection (for blue chips in Hong Kong) is
associated with higher liquidity. Chen et al. (2007) analyze the relation between S&P‟s Transparency
and Disclosure (T&D) rankings and liquidity of the constituent firms in the S&P 500 index, and
report that T&D rankings are negatively associated with firm liquidity measured by the quoted half
spread and the effective spread.
Focusing on within-country differences in governance provisions, Lambardo and Pagano (2000)
provide evidence of an inverse relation between shareholder rights and required returns on monthly
equity indices, which implies an inverse relation between investor protection and liquidity costs.
Attig et al. (2003) show that deviations of ownership from control increase bid-ask spreads in the
Canadian stock market. Chung et al. (2010) examine the relation between transparency-related
governance attributes and liquidity in the U.S. stock market, and find that firms with better
7
governance structure exhibit narrower quoted and effective spreads, smaller price impact of trades,
and lower probability of information-based trading.
Researchers have also argued that some of corporate governance mechanisms aiming at reducing
agency costs can also depress firm liquidity. Large shareholders and ownership concentration provide
more adequate internal monitoring, but reduce stock liquidity by creating information asymmetry
problems (Coffee, 1991; Bhide, 1993). Heflin and Shaw (2000) report that a higher level of
blockholder ownership, regardless of whether the blockholders are managers, is associated with
reduced firm liquidity. Conversely, liquidity discourages internal monitoring by reducing the costs of
„exit‟ of unhappy shareholders, and thus impairs corporate governance. Kahn and Winton (1998)
contend that market liquidity can undermine the effective control by large shareholders by giving
them excessive incentives to speculate rather than to monitor. Bolton and Thadden (1998) develop a
simple model to show that when a firm decides to set up a controlling block, it reduces the number of
shareholders who can participate in the trading of the firm‟s stocks, and therefore, this effectively
reduces market capitalization and hence, the liquidity of the stock.
The finance theory does not appear to provide a definite answer for the relation between the
overall quality of corporate governance and firm liquidity. In this study, we hypothesize that overall
corporate governance is positively related to firm liquidity in the emerging Chinese stock market for
the following reason. The Chinese stock market has a short history, the quality of disclosure is low,
boards are often inefficient, and information asymmetries between insiders and small investors are
severe (Chakrararty et al., 1998). This is consistent with Akerlof‟s (1970, p.497) observation that
“markets in underdeveloped countries often strongly reflect the operation of Lemons Principle.”
Better governed firms can assure more efficient operations of corporate boards, better protection of
8
minority shareholders‟ interests, and maintain more appropriate disclosure and better transparency.
Therefore, the major hypothesis of our study is posited as higher quality of governance decreases
information asymmetries, enhances investor confidence, and is positively associated with firm
liquidity.
3. Data and Methodology
Our sample consists of all non-financial listed companies traded on the Shanghai Stock
Exchange (SHSE) and the Shenzhen Stock Exchange (SZSE) over the 1999-2004 interval. We
exclude financial firms from this study because financial firms are abnormally large in size and their
book-to-market ratios have different implications from those of non-financial firms. We do not
analyze the post-2004 data because the ownership-split reform commencing in early 2005 generated
significant impacts on corporate governance, firm valuation as well as market liquidity. This data
screening process results in a sample consisting of firms varying from 918 firms at the end of 1999 to
1343 firms at the end of 2004 representing over 99% of the total number of listed companies traded
on the two stock exchanges. Table 1 presents the composition of sample firms for the SHSE and the
SZSE as well as the total number of listed firms over the sample period. Our data are collected from
the China Stock Market & Accounting Research Database (CSMAR).

3.1. Measuring corporate governance
In contrast to most corporate governance indices that are based on responses to survey questions
(e.g., Klapper and Love, 2003; Durnev and Kim, 2005; Black, 2005), we construct an overall
governance index for each Chinese listed firm to measure the quality of corporate governance based
on disclosed governance-related information in their annual financial reports. Bai et al. (2004) also
9
use a similar approach to construct a corporate governance index and examine the relation between
the corporate governance index and firm value for individual Chinese listed firms in 2000. We
classify the governance related information into 5 groups: expropriation of minority interests, board
of directors‟ structure and process, supervisory board structure and process, ownership structure, and
financial transparency and disclosure. We score a variable if it contributes to the quality of corporate
governance based on the finance and economics literature. These 5 groups consist of 17 variables in
total.1 The details of each variable and the scoring criteria are summarized in Table 2.
<Insert Table 2 about here>
Obtaining scores of the above individual variables, we construct a corporate governance index
each year by first summing a firm‟s scores of all non-missing variables and then divide the score by
the number of non-missing variables. This technique avoids the problem resulting from missing
variables of some individual firms. The corporate governance index (CGI) for each firm each year
has a value ranging from 0 to 1. A higher value of CGI indicates higher quality of governance.
However, we recognize that there is no theoretical guidance on the weightage of each variable in the
construction of corporate governance index. Therefore, we use the equal-weight technique to assess
the quality of governance in this study. Bai et al. (2004) use a similar approach to construct corporate
governance index, and examine the relation between overall corporate governance and firm values.
3.2. Empirical method
The relation between corporate governance and firm liquidity is estimated using the fixed effect
panel regression. This method accounts for potential endogeneity of corporate governance measure
1 In addition to the governance provisions of Bai et al. (2004), this paper also considers tunneling motivated
related part transactions, board size, state as the controlling shareholder, institutional ownership, attendance
rate of annual shareholders‟ meeting, and audit opinions in the construction of corporate governance index.
10
by controlling for potential unobservable firm-specific factors that could be driving both governance
and liquidity. Our empirical model is specified as
, , 1 ,i t i t j j t i tLIQ CGI (1)
where LIQi,t is a liquidity measure for firm i in year t; CGIi,t-1 denotes firm i‟s corporate governance
index in year t-1; and Xj,t denotes the jth control variable; λi denotes the firm-level fixed effect.
There is still a concern regarding the endogeneity problems in the examination of the relation
between corporate governance and liquidity. It is arguable that market liquidity affects corporate
governance because greater liquidity makes it easier for active shareholders to build positions so as to
effect changes in corporate policies. Moreover, market liquidity allows for the more effective use of
secondary equity market for corporate-control activities. We attack this issue by examining the
relation between liquidity and lagged corporate governance index as specified by equation (1).
Following the literature, we choose firm size (SIZE), leverage (LEVERAGE), book-to-market ratio (BM),
and volatility (VOL) as control variables in this study.
We use two commonly used measures of liquidity. The first liquidity measure is the tradable turnover
ratio (TURNOVER), which is defined as the average of monthly turnover ratios for a firm during the year,
and monthly turnover ratio is the number of shares traded in the month divided by total tradable A-shares
outstanding at the end of previous month.2 We use tradable turnover rather than total turnover, which is
the number of shares traded in a month divided by total shares outstanding, because a large portion of
shares (state shares and legal-entity shares) in a typical Chinese listed company is not allowed to trade.
Consequently, total turnover can be a distorted measure of liquidity in the Chinese stock market (Wang
2 Several extant studies have used turnover as a measure of trading volume of a stock, for example, Datar et al.
(1998), and Lee and Swaminathan (2000). Turnover is arguably superior to dollar trading volume because raw
trading volume is unscaled and highly correlated with firm size. As a result, it is difficult to distinguish between
the volume and size effects.

and Chin, 2004).
The second measure for liquidity used in this study is the daily ratio of absolute stock return to its
trading volume averaged over a given period. This measure was proposed by Amihud (2002), which
is termed as Amihud ratio (AMIHUD) hereafter. Intuitively, the Amihud ratio can be interpreted as
the daily stock price response associated with one dollar of trading volume, which is consistent with
Kyle‟s (1985) concept of illiquidity, i.e. the response of price to order flow. We first calculate a daily
ratio for firm i as
, , ,/i t i t i tDaily Ratio R VOL
where ,i tR is the return of firm i for day t; ,i tVOL is the trading volume in Renminbi (RMB) in day t.
We then compute the annual Amihud ratio as an average of daily Amihud ratios for firm i in a
year as

Anual Ratio D R VOL
(2)
where D is the number of trading days in a year for firm i.
4. Empirical Results
Summary statistics and contemporaneous correlations between these variables are presented in
Table 3. The average corporate governance index (CGI) is 0.46, with a standard deviation of 0.07.
The mean monthly turnover ratio over the 1999-2004 interval is as high as 27.4%, which means that
it takes about 4 months for tradable shares of a firm to change hands once. This figure is comparable
to that documented in Wang and Chin (2004) but is significantly higher compared to that in the U.S
market, which is, for example, about 4% in Lee and Swaminathan (2000). The Amihud ratio that is
multiplied by 1,000 has a mean of 46.79, and appears highly volatile, with a standard deviation of
12
126.81.
Logarithm of total assets is used as a proxy for the firm size (Morck, Shleifer, and Vishny, 1988;
McConnell and Servaes, 1990). The mean SIZE of our sample is 21.05. The average leverage and
book to market ratio are 0.51 and 0.35 respectively over the sample period. The mean monthly return
volatility (VOL) is about 24.95%.The right-hand-side panel of Table 3 shows the contemporaneous
correlations between the dependent and independent variables.
<Insert Table 3 about here>
The results of estimating equation (1) are reported in Table 4. The key finding in Table 4 is that
corporate governance index is significantly associated with liquidity. For the turnover regression, the
estimated coefficient for CGI is 0.097 (t= 3.28) when all control variables are included. This implies
that an increase of 1 CGI point (out of 100), the monthly (annual) turnover ratio of a firm will be
increased by 0.1% per month (1.2% per year) in the subsequent year, on average. For the Amihud
(illiquidity) ratio regression, the estimated coefficient for CGI is –0.972 (t= -2.26) when all control
variables are included. The results in Table 4 are consistent with extant findings that better governed
firms are associated with higher financial and operational transparency, less information asymmetry,
and thus higher liquidity (Botosan, 1997; Bhattacharya and Daouk, 2002; Brockman and Chung,
2003; Chen et al., 2007, Chung et al., 2010). Consistent with the literature, firm size is positively
related to liquidity (Amihud and Mendelson, 1986), leverage and book-to-market are negatively
related to liquidity (Perotti and von Thadden, 2003; Lang and Lundholm, 1999). These results hold
true when both the turnover and the Amihud ratios are employed as the dependent variables. There
appears to be a positive relation between turnover and volatility, however, the positive liquidity –
volatility relation does not exist when the Amihud ratio is used as a measure of illiquidity. The
13
estimated coefficients for AMIHUD are of wrong signs, although they are insignificantly different
from zero.
<Insert Table 4 about here>
We also explore the relation between subindices of corporate governance and firm liquidity. An
examination of subindices of corporate governance serves as a robustness test of the relation between
overall governance and liquidity because one may concern that some of governance variables
themselves may be the determinants of liquidity, for example, ownership and ownership
concentration.3 We construct two subindices: the board of directors-based index and the ownership
structure-based index. The subindex is constructed by first summing the scores of individual
variables and then scaling the scores using the number of non-missing variables for each group. The
governance provisions related to board of directors are less likely to be the determinants of or
affected by liquidity than those related to ownership structure. The results of regressing liquidity on
lagged subindices of corporate governance are reported in Table 5. To contain space, we only report
the regression results using turnover as the liquidity measure.4 Consistent with the results in Table 4,
the coefficient estimates for subindices of corporate governance are positive and significant at the 5%
level or higher for all regressions, and the estimated coefficients for control variables are all of
expected signs and statistically significant.
<Insert Table 5 about here>
5. Conclusions
3 Although we focus on the relationship between liquidity and lagged corporate governance index, one may
argue that some governance provisions at the firm level vary a little across years, and the positive
governance-liquidity relationship may arise from those governance provisions that determine liquidity. 4 The results of regressions using Amihud ratio as the liquidity measure are similar to those in Table 4, which
are in general less significant than those using turnover as the liquidity measure.

In this paper, we examine the cross-sectional relation between overall corporate governance and
firm liquidity in the Chinese stock market. We employ a corporate governance index to measure
overall quality of corporate governance for each firm traded on the Shanghai and the Shenzhen stock
exchanges over the 1999-2004 interval. The index contains 17 governance elements, which uses, to
our best knowledge, the most information available publicly in the construction of corporate
governance index in the Chinese stock market. We find a positive and significant relation between
corporate governance and firm liquidity after accounting for factors influencing firm liquidity. An
increase of 1% in corporate governance index is associated with a 1.2% increase in a firm‟s annual
turnover in the subsequent year. We also examine the relation between subindices of corporate
governance and liquidity and between individual corporate governance elements and liquidity. We
report that both ownership structure-based and board of directors-based governance indices are
positively related to firm liquidity; 12 out of 17 corporate governance elements are positively
associated with firm liquidity.
This paper appears to be the first study to investigate the relation between overall corporate
governance quality and firm liquidity. Our results have important implications for academics to better
understand the benefits and costs of corporate governance. Extant literature has documented that the
level of corporate governance is positively associated with firm value or stock returns. Our findings
on the positive relation between corporate governance and firm liquidity imply that the value creation
effect of corporate governance reported in the extant literature tends to be underestimated. Our
findings also have implications for stock market regulators to actively promote corporate governance
reform. The positive relation between overall corporate governance and liquidity relieves the concern
that enhancing corporate governance dampens liquidity (Coffee, 1991; Bhide, 1993; Bolton and
15
Thadden, 1998).

Corporate governance and firm liquidity
This table shows the (fixed effects) panel regression result of firm liquidity in year t on corporate governance index in
year t-1. The sample period is from 1999 to 2004. The dependent variables are the turnover ratio (TURNOVER) and the
Amihud ratio (AMIHUD) respectively. Turnover is defined as the average of monthly turnover ratios for a firm in year t,
and monthly turnover ratio is the number of shares traded in a month divided by total tradable A-shares outstanding at the
end of year t-1. CGI is the corporate governance index of a firm. SIZE is the logarithm of the firm‟s total assets at the end of
year t-1. BM is the book to market ratio where the market value is measured using the share price at the end of year t-1
multiplied by total shares outstanding. Leverage is measured as the total debt over the total assets at the end of year t-1.
VOL is the monthly return standard deviation in year t. EX and INDUSTRY are dummies variables for two stock exchanges
and 12 industries respectively. The numbers in parentheses are the z-statistics computed based on the White's
heteroskedasticity- consistent standard errors. *, **, and *** indicate significance at the 10%, 5% and 1% levels
respectively.

Subindices of corporate governance and firm liquidity
This table shows the (fixed effects) panel regression results of turnover in year t on the board of directors-based and
ownership structure-based subindices of corporate governance in year t-1 respectively. The sample period is from 1999 to
2004. Turnover is defined as the average of monthly turnover ratios for a firm in year t, and monthly turnover ratio is the
number of shares traded in the month divided by total tradable A-shares outstanding at the end of year t-1. SIZE is the
logarithm of the firm‟s total assets at the end of year t-1. VOL is the monthly return standard deviation in year t. BM is the
book to market ratio where the market value is measured using the share price at the end of year t-1 multiplied by total
shares outstanding. Leverage is measured as the total debt over total assets at the end of year t-1. EX and INDUSTRY are
dummies variables for the 2 stock exchanges and 12 industries respectively. The numbers in parentheses are the
