【摘要】 越来越多的实证研究证明，股权集中和大股东的出现成为世界范围内的公司治理潮流。本文试图在“大股东—公司治理”的研究框架下，探讨大股东在公司治理中的角色和定位问题。在此研究框架下，本文还对全流通证券市场大股东行为特征问题进行了深入剖析。本文首先对研究涉及的几组概念进行了阐释，然后文章对公司治理理论进行了系统的论述。以此为基础，在委托代理理论的视角下，分析了大股东与中小股东之间存在着的委托代理关系。本文重点分析了我国上市公司大股东侵害行为发生的原因以及解决的途径。首先从我国证券市场定位、股权结构以及公司治理机制、证券监管和对投资者法律保护等方面定性的分析了大股东侵害行为发生的原因，然后建立数学模型进行定量的研究。在对限制大股东侵害行为模型分析的基础上，本文从改善公司治理机制、加强证券市场监管部门的监管和完善法律建设等三方面提出了减轻大股东侵害行为的对策。更多还原

Under the frame of“large shareholders—corporate governance”, the rule and position of large shareholders in corporate governance will be discussed. Furthermore, the characteristic behaviors of large shareholders in the full circulation of stock market will be deeply analyzed and compared.Firstly the background of this study is summarized in the beginning of the paper. Then the theory of corporate governance is completely demonstrated. Based on these, we can get the conclusion that large shareholder is agency, but small shareholder is principle from the theory of principle-agent.This paper has especially analyzed the problem of expropriation by large shareholders of public corporations on small investors and how to settle the problem in China. We find the reason why large shareholders expropriate on small shareholders with qualitative analysis, from the securities market orientation of out country, ownership structure, corporate governance, portfolio supervision and investor legal protection, then set up mathematic model with quantitative analysis. On the basis of the model, we put forward three measures to restrain the expropriation by large shareholders. First, improving corporate governance which is focus on perfecting the function of the board of directors, building manager’market and company control power market. Second, strengthen the supervision of the supervision department of security market.
