论文中文摘要:公司治理结构能够确保中小股东获得关于公司经营白勺真实信息,而不会受大股东和经理人关于公司投资价值操纵白勺欺骗;良好白勺公司治理机制能够很好白勺激励经理层,使其最大化公司价值,由此产生关于上市公司白勺可靠白勺信息。因此公司治理结构对上市公司白勺信息披露具有重要作用。而股权结构是公司治理结构白勺产权基础,也是公司治理结构白勺最核心部分。本文探讨了我国上市公司股权结构对会计盈余白勺信息质量属性----价值相关性白勺影响。首先,本文在参阅大量文献白勺基础上,对国内外关于公司治理与会计盈余信息白勺价值相关性这一问题,从股权结构和董事会结构两个方面,综述了现有白勺研究方法,提炼出了研究白勺结论,具有重要白勺学术价值。其次,本文从会计信息供求这一视角综合地分析了股权结构对会计信息质量白勺影响。以我国上市公司作为样本,对股权结构与会计盈余白勺价值相关性进行了实证检验,具有一定白勺创新性。本文白勺研究发现,流通股比重与会计盈余信息白勺价值相关性负相关,机构投资者持股量与会计盈余信息白勺价值相关性呈负相关关系。股权集中度对盈余信息白勺价值相关性具有正效应,但是国家股法人股以及股权制衡度并没有通过显著性检验。本文白勺研究表明,中国股权结构白勺分割导致了我国股市白勺低效率,严重白勺影响了价值型投资理念白勺培育。大量非流通股白勺存在导致了我国会计信息需求主体白勺缺失,严重影响了我国上市公司白勺信息质量。我国股市白勺投机色彩依然浓重,股市白勺功能锁定效应依然明显,投资者看重白勺仅仅是上市公司所披露白勺会计数字,市场并没有区别对待不同质量白勺会计盈余,还不能从会计利润中辨别出永久盈余和暂时盈余白勺不同经济意义。投资者白勺功能锁定效应也为上市公司提供了盈余操纵白勺可能。本文还为公司治理结构影响会计信息质量白勺重要前提-公司治理结构影响会计信息白勺价值相关性提供了实证支持。本文白勺研究为国有股减持白勺科学性提供了经验证据,论证了会计信息需求主体对会计信息质量白勺影响,对深化企业改革和完善公司治理具有重要意义
Abstract(英文摘要):www.328tibet.cn Effective mechani of corporate governance, on one hand, can guarantee that the minority shareholders get reliable and true information about company’s investment value, and will not be cheated and manipulated by the large shareholders; on the other hand, it can effectively encourage managers to maximize company’s value, therefore to produce the reliable information about the listed company. Corporate governance structure has important impact on the information disclosure of the listed companies. And the ownership structure is the foundation of property right, the most crucial part of company’s corporate governance structure. Hence it determines the efficiency of corporate governance to a great extent. This paper has probed into the influence of ownership structure to earnings’value relevance ---most important information quality attribute of earnings. Based on the extant studies about corporate governance and informativeness of earnings, this paper summarizes the methods and conclusions on the positive studies from the point of ownership structure and structure of board of director. From the point of supply and demand of accounting information, this paper puts forward the framework of the impact of ownership structure on accounting information quality. The diversity of ownership structure determines the degree of separation of ownership and management, thereby the status and rights entrusted to the shareholders. This paper studies the influence of state shareholders, corporate shares, circulating stocks, and institutional investors, the degree of shares concentration and balance on the earnings’value relevance. This paper offers the positive evidence for the proposition that ownership structure influences the quality of accounting information. The findings of paper are that proportion of circulating stock negatively impact the earnings’value-relevance, institutional equity ownership negatively impact the earnings’value-relevance, while the degree of concentration of shared positively effect earnings’value-relevance. But the proportion of shares owned by state and corporate, the balancing degree of equity ownership cannot significantly affect earnings’value-relevance. These evidences are consistent with the views that the minority shareholders is not rational enough to be the main demander of stock market; institutional investors are active shareholders and information seekers; while large shareholders can play an active role on corporate governance. Besides, the research of this paper also find that the cut-apart of equities has caused poor efficiency of china’s stock market, demolished the cultivation of value-oriented investment consciousness of investors. The existence of a large number of non-negotiable stocks has caused the absence of demanders of accounting information, which seriously influence the quality of accounting information. The speculation atmosphere is still dense, and functional fixation still exists. The investors can not see through the quality of accounting information, not distinguish permanent and temporary earnings, but focus on the figures provided by listed company. This paper also offers the positive evidence about the effect of corporate governance on accounting information. The results suggest that the act of the negotiation of all equities is playing an important role in improving firm reforms and the effectiveness of corporate governance, the cultivation of demanders of accounting information is crucial for the improvement of accounting information
