For Chinese companies that cross-list in Chinese A share and Hong Kong (H share) markets, the H share price has been consistently lower than the A share price by an average of 85% in recent years. This is puzzling because most institutional differences between the two markets have been eliminated since 2007. The purpose of this study is to explain the puzzle of the price difference of A+H companies.

Using all A and H share Chinese firms in the period 2007–2013 and a simultaneous equations approach, this study identifies three new explanations for the recent price difference.

First, utilizing a unique earning quality measure that is directly related to non-persistent components of fair value accounting under International Financial Reporting Standards (IFRS), this study finds that the lower the earnings quality, the lower the H share price relative to the A share price, and hence the greater the price difference. Second, the higher the myopic investor ownership in A share firms, the larger the A share price relative to the H share price. Third, the short-selling mechanism introduced to the A share market since 2010 helps reduce the price difference.

First, this study identifies three new explanations for the puzzle of the AH price difference which remains substantial even after the institutional and accounting standards differences between the two markets were eliminated. Second, we examine the impact of the implementation of fair value accounting under IFRS in an emerging market on the pricing difference of cross-listed shares and reveal that it can induce an unintended negative consequence on the pricing difference of cross-listed shares. Third, this study contributes to the literature on short sales by providing its mitigating role in pricing differences across two different markets. Finally, this study makes improvements in research design, which utilizes a unique measure of earnings quality that is directly related to the implementation of IFRS and a simultaneous equations approach that minimizes endogeneity concern.

The Chinese capital markets are divided into two segments comprising of A-shares (traded by domestic investors) and B-shares (traded by foreign investors). Firms issuing A-shares are required to produce accounting reports under the Chinese Accounting Standards (CAS) and firms issuing B-shares are required to report under the International Accounting Standards (IAS). The purpose of this paper is to investigate the comparative value-relevance of accounting information in the Chinese capital markets, in particular whether the value-relevance associated IAS exceeds that of CAS.

This study undertakes a capital market research approach. Two statistical models are employed to test the value-relevance of competing accounting information on share prices: the Price Model and the Return Model. This study takes advantage of the parallel reporting frameworks governing the A-share and B-share markets buy using the same firms which issue both A-shares and B-shares.

The analysis supporting the study demonstrates that both CAS and IAS information is value relevant to investors in the Chinese capital markets but that IAS provide more useful information. Additionally it is observed that reconciliation variables (representing the discrepancy between IAS- and CAS-based accounting figures) are not significant in explaining market valuation or returns on stock.

This study provides evidence of value-relevance of accounting reports on the Chinese capital markets for the period of 1999-2005. The period under investigation captures the significant development in China's accounting regulations which took place in 1998 and 2001. The recent shift in accounting regulations in China from CAS to IAS is expected to improve the dissemination of financial information by publicly listed Chinese firms.

This study investigates the reporting requirements on the Chinese capital markets during a period in which accounting reporting requirements underwent a significant change as part of the internationalization of accounting standards. Both A- and B-share markets were investigated simultaneously in order to provide an objective analysis and avoid sampling selection bias present in other studies.

The recent shift in accounting regulations in China from CAS to IAS is expected to improve the dissemination of financial information by publicly listed Chinese firms.

This paper extends previous research on value-relevance of accounting reports in the Chinese capital markets by capturing the period in which the reporting requirements had experienced significant change. This paper also takes advantage of the dual reporting framework in order to mitigate potential sampling bias present in previous studies and employs a reconciliation variables not previously used.

The purpose of this paper is to study the effects of short‐sale constraints and differences of opinions on the price premium of dual listed Chinese A‐H shares.

The analysis mainly follows the Miller's model, which indicates that the relaxation of stringent short‐sale constraint could reduce the upward bias in stock prices. Following the literature, the paper uses the idiosyncratic return volatility and monthly turnover rate as two main proxies of differences of opinions.

This study shows that the high level of A‐share differences of opinions will lead to the high price premium of A‐share portfolio with the short‐sale constraint in the A‐share market. However, the high level of H‐share differences of opinions has no effect on the price premium of H‐share portfolio and has also positively contributed to the A‐share price premium. The price premium of shorted A‐share portfolio is declined more significantly than those of non‐shorted ones after the relaxation of short‐sale constraint in the A‐share market.

The findings in this study provide further evidence that dual listed Chinese A‐shares with high level of differences of opinions and short‐sale constraints tend to be overvalued.

This study supports Miller's hypothesis that with the control of short‐sale constraint, the high level of differences of opinions could lead to the high degree of overvaluation of A‐share portfolio. The market capitalization and book‐to‐market ratio of A‐shares also generate significant positive effect to the A‐share price premium. Finally, the introduction of short‐sale mechanism in A‐share market could partially eliminate the mispricing of dual‐listed A‐shares and improve the price efficiency of A‐share market.

This study is mainly focused on the joint effects of differences of opinions and short‐sale constraints on the A‐share price premium. The new short‐sale policy in A‐share market in March 2010 provides us an opportunity to study the effect of relaxation of stringent short‐sale constraint on the A‐share price premium. In the literatures so far, all studies assumed A‐shares are strictly prohibited to be sold short.

The purpose of this paper is to investigate the relative value relevance of accounting measures based on Chinese Accounting Standards (CAS) and International Financial Reporting Standards (IFRS) in relation to both A‐share and B‐share markets during three distinct phases (1994‐1997, 1998‐2000 and 2001‐2004) over which CAS were progressively harmonized with IFRS.

Using data for 86 Chinese listed companies which issued both A‐ and B‐shares, the authors employ the price model to test for the association between CAS‐based and IFRS‐based accounting information, and A‐share and B‐share prices. The J‐test was employed to determine the relative value relevance of the information based on the two sets of accounting standards.

Overall, the authors find that for both the A‐share and B‐share markets, both CAS‐based and IFRS‐based accounting information are value relevant, but IFRS‐based information is more value relevant than the CAS‐based information. However, the magnitude of the differences between the explanatory powers of the CAS‐ and IFRS‐based accounting information narrowed significantly in the 2001‐2004 period in both the A‐share and B‐share markets. The results are robust to the deflator used and the stock exchange on which the companies are listed.

The results have implications for China and other transitional economies attempting to integrate IFRS with a uniform accounting system.

The paper provides the first comprehensive empirical evidence as to whether or not the progressive harmonization of CAS with IFRS improved the value relevance of CAS‐based accounting in China and contributes to the debate on the (ir)relevance of IFRS in emerging and transitional economies.

This paper aims to investigate whether the accounting reform in China has improved the relevance of China's accounting information. It seeks to investigate the association between earnings and book value of equity to share returns before and after the introduction of the Accounting System for Business Enterprises (ASBE) in 2001 for A‐ and A&B‐share firms.

The paper employs the return regression model. The pre‐ASBE period is designated as 1997 through to 2000, and the post‐ASBE period is designated as 2002 through to 2004. All firms listed on the Chinese stock market during the investigation period constitute the sample.

It is found that accounting information better explains share returns for both A‐share firms and A&B‐share firms in the post‐ASBE period. The paper also finds that the book value of equity for A&B‐share firms is incrementally value relevant to that of A‐share firms in the post‐ASBE period.

Further studies will contribute to understanding how governance mechanisms and liquidity influence the association between accounting information and share returns in the Chinese A‐share market.

The findings provide empirical evidence regarding the relevance of accounting information in emerging markets.

The paper contributes to the extant value relevance literature by investigating time periods surrounding the issue of ASBE in 2001 in the Chinese stock market.

The purpose of this paper is to examine the evidence of herding phenomenon, spill-over effects related to herding and whether herding is driven by fundamentals or non-fundamentals for various sub-periods and sub-samples.

The cross-sectional absolute deviation model is applied to China’s A- and B-share markets in combination with fundamental information.

Herding is prevalent on both A- and B-share markets. In detail, investors on A-share market herd for small and growth stock portfolios irrespective of market states while they only herd for large or value stocks in down market, therefore leading the whole herding behaviour to be pronounced in down market. Comparatively, on B-share market, herding is robust for various investment styles (small or large, value or growth) or market situations. Additionally, spill-over effects related to herding do not exist no matter from A-shares to B-shares or from B-shares to A-shares. Moreover, investors on B-share markets tend to herd as the response to non-fundamental information more frequently during financial crisis.

Investors on A- and B-share markets tend to herd as the response to non-fundamental information more frequently during financial crisis. Analysing the herding behaviours could be helpful in controlling the financial risk.

The purpose of this paper is to investigate the impact of short selling and margin trading on the price discovery and price informativeness of cross-listed firms, using a sample of Chinese firms listed on the China and Hong Kong stock exchanges.

The sample consists of 67 Chinese cross-listed firms on A-share and H-share markets out of which 18 firms are allowed to be sold short/ traded on margin since March 2010. Using pre- and post-event period, the authors compare and contrast various market microstructure variables. The contributions of the home (A-share) and overseas (H-share) markets to the incorporation of new information into prices are calculated following the permanent-transitory approach of Gonzalo and Granger (1995) as well as the adverse selection component of Lin et al. (1995).

The findings indicate that for the group of Chinese cross-listed firms that are not allowed to be sold short or bought on margin, the home (A-share) market contributes more to the price discovery process over time. However, for the group of cross-listed firms that are eligible for short selling and margin trading, the authors observe no significant difference in the contribution of either A- or H-share markets to the price discovery. The contribution of home market for these firms is even lower around the announcement of major events. The authors further find that while the short sale activities appears to be informative, measured by the adverse selection (AS) component of spread, on the whole they have not led the A-share markets to be more informative.

The sample of cross-listed Chinese firms that are allowed to be sold short or bought on margin are rather limited. Hence, the results should be read with some caution.

The removal of short selling constraints appears to improve the contribution of the respective markets to the process price discovery, in the case for larger cross-listed firms.

The authors shed new lights on how the introduction of short selling and margin trading impacts on the price discovery of the Chinese cross-listed firms. A further contribution of the study is the use of high frequency data, while most of the previous studies on the Chinese markets use daily data.

The purpose of this paper is to investigate the momentum phenomenon in two market segments of the Chinese stock market – the Class A share market and Class B share market over time period spanning from January 1996 to December 2010.

The authors largely follow Jegadeesh and Titman (1993) paper; the authors decompose the momentum returns following the procedure first proposed by Jegadeesh and Titman (1995). In addition, a liquidity factor (Pastor and Stambaugh, 2003) and a share ownership factor (Wang and Xu, 2004) are incorporated in the procedure to gauge the contribution of liquidity and the dynamics of share ownership towards the momentum returns, respectively in the two segments of the Chinese stock market.

The authors find compelling evidence showing distinctively different momentum phenomena exist in the two market segments of the Chinese stock market. Specifically, the momentum phenomenon is more pronounced in the Chinese Class A share market compared to those found in the Chinese Class B share market. Through decomposing the momentum returns, the authors find evidence showing the dismal momentum returns observed in the Class B share market can be attributed to markedly weakened contributions of the liquidity factor and the share ownership factor.

Relatively short sample time horizon compared to the most of major financial markets such as USA and UK. The number of B shares has been rather limited.

Subsequent to the opening of the Chinese Class B share market to domestic investors in 2001 and the opening of the Chinese Class A share market to qualified foreign institutional investors (QFII) in 2003, the empirical evidence found in this study provides a crucial reference point for domestic and foreign portfolio strategists in guiding them to form suitable portfolio strategies concerning investments in a nascent financial market such as the Chinese stock market, fraught with volatility and speculative trading behaviour.

It offers a comprehensive view of the momentum phenomenon in the Chinese Class A and B share markets over the sample period from January 1996 to December 2010. Second, the reasons behind the dichotomy of the momentum returns found in the two market segments were investigated through decomposing the momentum returns based on Jegdeesh and Titman’s (1995) method while incorporating three new explanatory factors – the liquidity factor, share ownership factor and the under reaction towards firm-specific news factor.

A couple of extant papers have visited the topic before. yet this paper offers more comprehensive view on the existence of momentum premium in both Chinese Class A and B share markets and investigates the driving forces behind the subdued momentum returns observed in the B share market.

The opening up of B-share markets to domestic investors in 2001 is a landmark event in the development of the Chinese stock markets. This chapter aims to assess the possible changes in the market mechanism associated with this important event. A VECM-DCC-MVGARCH model is employed to investigate the market integration process in Chinese stock markets around the opening up of the B-share market to domestic investors. Our empirical results reveal that the Chinese stock markets were segmented before the opening up whereas they were integrated to some extent in the long-run after the opening up of B-share markets. Moreover, it is also found that A-share markets played a dominant role on the information flows between A-share and B-share markets; the short-run information flows between A-share and B-share markets were more rapid after the opening up of B-share markets.

This paper examines empirically Chinese stock price reactions to financial announcements for 2002. We find that B share prices react more strongly to negative financial announcements than A shares. The announcements can lead to excess returns. One explanation is that the markets are segmented by the inconvertibility of China’s currency, as well as by the structural change of investors. Meanwhile China listed companies need to improve their transparency and disclosure.
