【摘要】 股权结构是公司治理结构的产权基础,也是公司治理结构的最核心部分。根据最优股权结构理论,机构投资者在公司治理结构中发挥着重要的作用。当机构投资者在上市公司中拥有较高的持股比例时,通过监督管理层和董事会的行为,改善公司的信息披露状况,从而影响了上市公司会计信息的价值相关性。近年来,我国机构投资者保持了较快的发展势头。在各种政策支持下,目前以基金、券商、保险资金、社保基金、QFII等为主要力量的机构投资者已成为我国资本市场稳定发展的重要主导力量。与过去相比,研究国内机构投资者持股与会计信息质量的条件已经成熟。本文以2005年到2007年沪深股市有机构投资者持股的上市公司为样本,主要研究了机构投资者持股比例对上市公司会计信息的价值相关性的影响,对这一问题的研究可以从一个侧面回答我国的机构投资者与公司治理之间的关系。本文得出的结论是:在研究会计信息的价值相关性的价格模型(Ohlson Model)中引入机构投资者持股比例这个变量,能使会计盈余的价值相关性增强;并且在一定限度内,随着机构投资者持股比例的增加,会计盈余信息的价值相关性也逐渐增强,这也说明了机构投资者参与公司治理是有意义的。最后,本文提出了关于促进机构投资者发展及激励机构投资者参与公司治理的几点建议。
【Abstract】 The ownership structure is the foundation of property right and the most crucial part of corporate governance structure. According to the theory of power balance with shareholder structure, institution investor has an important impact on corporate governance. A large stake in listed company will motivate institutional investors to monitor the management and board of directors of the company and improve information disclosure. As a result, institutional ownership impacts the value relevance of earnings.In recent years, China has greatly improved its investment environment for various forms of institutional investors and diversified their sources of investment. Institutional investors, including investment funds, stock brokerages, insurance companies, pension funds and government sanctioned foreign institutional investors (QFII), have become the top movers and shakers in China’s securities markets. The increase of institutional ownership provides new opportunities for research on institutional investor and the quality of accounting information.This paper clarifies the function of institutional investors in corporate governance through the influence of institutional ownership on value relevance of accounting information. Studies of Shanghai-listed and Shenzhen-listed A-shares data 2005-2007 find that relationship is clear between institutional ownership and value relevance of earnings. Results show that institutional ownership is positively associated with earnings’explanatory power for prices. Moreover, with the mounting institutional holding, their explanatory power rises, an indication that institutional investors are beginning to play a role in corporate governance in recent years.Finally, the article also discusses why and how to promote institutional investors in corporate governance.
