摘要:信息不对称问题由来已久,如今更是引起了监管部门和学术界的高度关注,其中缘由当然不仅仅是信息不对称使得公司的资本结构和融资问题变得更加复杂,还表现在其让证券市场的流动性受到阻碍,而流动性是一国证券市场的核心运行效率之一。因此,研究信息不对称的重要影响因素——股权结构,以及两者的关系是本文的研究对象,本文首先基于Glosten 和Harris(1988)模型估计沪深股市的信息不对称程度;然后在此基础上进一步考察了股权结构因素对交易中的信息不对称程度的影响,实证结果表明,国有和法人股比例、流通股比例、股权集中度、股价及成交量与信息不对称程度呈正相关关系;机构持股比例、管理层持股比例及股权转让比例与信息不对称程度呈负相关关系。文章在实证研究的基础上,提出了相关政策建议。64009

Title Asymmetric information and ownership structure: An
Empirical Study Based on China listing Corporation
Abstract
Long-standing problem of information asymmetry, is now attracted the attention of regulators and academic circles, the reason of course is not only the information asymmetry makes the capital structure and financing problems become more complex, but also in the securities market liquidity is hindered, and liquidity is one of the core operation of the securities market efficiency. Therefore, important influence factor of information asymmetry -- ownership structure, as well as the relationship between the two is the research object of this paper .Firstly I measure the degree of information asymmetry in China’s stock market using the techniques of Glosten,Harris(1988). Then I analyze the influence of ownership structure on information asymmetry. The conclusion shows that state shareholders,legal person share,circulating shares,the degree of concentration of shareholders,price and volume have positive impact on information asymmetry, while institution investor, manager shareholders and the transfer of shares have negative pact on information asymmetry. Based on the empirical results, I finally give some policy recommendations.
