【摘要】：中国会计准则国际趋同的改革迫切要求研究者对已存的改革效果进行评价。从准则趋同上看，中国会计准则（CAS）与国际财务报告准则（IFRS）仅存在个别项目的差异。从实务趋同上看，现有研究主要是通过净利润差异、价值相关性、盈余质量差异、经济后果几个视角对我国会计准则国际趋同的成效进行检验。这些研究很少涉及到盈余稳健性视角下的CAS国际趋同的研究，仅有的研究大多也只完成了2006版《企业会计准则》实施后，我国会计准则实质趋同效果的评价工作。本论文在借鉴国内外研究者相关研究成果的基础上，从盈余稳健性视角全面梳理了自1985年《中外合资经营企业会计制度》正式发布以来，，我国会计制度改革的研究成果。分别从会计准则的形式趋同和实质趋同两个层面展开研究，形式趋同研究按照我国会计准则中稳健性原则运用的程度，将我国会计准则的改革分为五个阶段。并根据盈余稳健性的理论测定方法得出结论。实质趋同研究以1997-2011年期间同时发行A股和H股的上市公司为研究样本，以H股报告盈余作为IFRS报告盈余稳健性水平的标准，采用盈余—股票报酬模型考察了A股报告盈余稳健性水平和H股报告盈余稳健性水平的差异和变化趋势，并通过配对样本组的方法进行了一系列的敏感性测试，控制了报告盈余种类、公司规模、不同行业、市场有效性等因素的影响。从而，为我国会计准则的国际趋同效果的评价提供了证据。本文的研究结论表明：AH股公司的A股和H股报告盈余整体上均呈现出稳健性。分阶段来看，A股报告盈余在1997-2001年期间未呈现稳健性，其余阶段均表现出稳定的盈余稳健性水平，且2007-2011年的提升很明显。H股报告盈余稳健性水平在各个阶段没有出现明显的变化。A H股报告盈余稳健性水平的差距在2007-2011年大幅减小。在一系列敏感性测试控制多种影响因素后，上述结论未有明显变化。而AH股公司的A股报告盈余稳健性水平在各阶段均高于配对样本组A股报告盈余稳健性水平，这主要是AH股公司受到两地监管和双重披露的影响，说明证券市场监管也对我国会计准则国际趋同的效果产生影响。
[Abstract]:The reform of international convergence of Chinese accounting standards requires researchers to evaluate the existing reform effect. From the point of view of the convergence of standards, there are only some differences between Chinese accounting standards (CAS) and International Financial reporting Standards (IFRS). From the point of view of practical convergence, the current research mainly tests the effectiveness of international convergence of Chinese accounting standards from the perspectives of net profit difference, value correlation, earnings quality difference and economic consequences. These studies rarely involve the international convergence of CAS from the perspective of earnings conservatism, and most of the only studies have only completed the evaluation of the effect of substantive convergence of accounting standards in China after the implementation of the 2006 edition of Accounting Standards for Enterprises. Based on the relevant research results of domestic and foreign researchers, this paper summarizes the research results of accounting system reform in China from the perspective of surplus conservatism since the official release of the Sino-Foreign Joint Venture Accounting system in 1985. From the two aspects of formal convergence and substantive convergence of accounting standards, the study of formal convergence is divided into five stages according to the degree of application of conservatism principle in accounting standards of our country. A conclusion is drawn according to the theoretical measurement method of surplus robustness. The substantial convergence study takes the listed companies that issued A shares and H shares simultaneously from 1997 to 2011 as the research samples, and takes the H shares' reported earnings as the standard of IFRS's reporting earnings soundness. In this paper, the differences and trends of A shares' reported earnings robustness and H shares' reported earnings' soundness are investigated by using the earnings and stock return model, and a series of sensitivity tests are carried out by paired sample groups. Control the types of reported earnings, company size, different industries, market effectiveness and other factors. Thus, it provides evidence for the evaluation of the international convergence effect of Chinese accounting standards. The conclusion of this paper shows that the A-share and H-share reported earnings of AH companies are all robust as a whole. From a phased perspective, A shares reported surpluses did not show robustness during 1997-2001, while the rest of the periods showed stable levels of surplus soundness. And the increase in 2007-2011 is obvious. The level of H-share reported earnings soundness has not changed significantly at all stages. The gap between A-H shares reporting earnings soundness level decreased sharply in 2007-2011. After a series of sensitivity tests controlled for a variety of factors, the above conclusions did not change significantly. However, the level of A share earnings robustness of AH companies is higher than that of A shares reported by matched sample groups at all stages, which is mainly due to the influence of dual regulation and double disclosure of AH stock companies. It shows that the regulation of securities market also has an impact on the effect of international convergence of accounting standards in China.
