【摘要】：作为资本市场的主体,上市公司不仅对实体经济产生影响,还会对投资者形成重要影响,由于委托代理关系的存在,对其监管将是保护投资者,提升市场效率的重要手段。由于国内外会计准则存在较大差异,监管层专门针对B股上市公司实施双重审计制度以提升其信息的有效性,伴随2007年国内外会计准则的趋同,强制性双重审计制度被取消,而有关这一制度是否有助于提升上市公司的治理效率的问题,国内学者尚未形成一致的结论。本文选取2001-2009年在B股市场上市的公司作为研究对象,并以同期A股上市公司作为对照组,以2007年强制性双重审计取消为时间节点,选取双重差分模型,采用事件研究法从实证的角度分析了制度变更对B股上市公司治理效率的影响。结论表明,以盈余管理、审计费用和非标准审计意见作为上市公司治理效率的代理变量,强制性双重审计制度总体上具备显著的公司治理效应。该结论支持了外部审计对公司治理的有效性,并能够为国内资本市场制度建设提供建议和参考。
[Abstract]:As the main body of capital market, listed companies not only have an impact on the real economy, but also have an important impact on investors. Because of the existence of principal-agent relationship, the supervision of listed companies is to protect investors. Because there are great differences in accounting standards at home and abroad, the supervision layer implements double audit system to enhance the effectiveness of the information of listed companies in order to improve the efficiency of the market. In 2007, with the convergence of accounting standards at home and abroad, the mandatory double audit system was abolished, and whether this system will help to improve the efficiency of governance of listed companies. Domestic scholars have not yet reached a consistent conclusion. This paper selects the companies listed in the B-share market from 2001 to 2009 as the research object, and takes the A-share listed companies as the control group in the same period, and takes the mandatory double audit cancellation as the time node in 2007. The double difference model is selected to analyze the effect of system change on the efficiency of B share listed company from the point of view of empirical research. The conclusion is that earnings management is used. Audit fees and non-standard audit opinions are the proxy variables of corporate governance efficiency. The conclusion supports the effectiveness of external audit on corporate governance and can provide suggestions and references for the construction of domestic capital market system.
