中文摘要：

以往关于股东间合作问题的研究存在严重不足：一是没有系统地阐明和分析股东间的合作机制：二是纯粹的“经济人”假设与现实中多重人性严重不符，研究成果解释力和应用性都比较差：三是仅仅关注大股东之间的合作，而忽视了广大中小股东在合作机制中的作用。鉴于此，在综合考虑“经济人”、“社会人”和“复杂人”等人性假设的基础上，本研究构建起一个由经济因素、制度因素、情感与行为因素共同构成的股东间合作模型，并系统地阐述了股东间合作机制的构建机理。根据中国上市公司股权结构特征，分别提出并讨论了“一股独大”、“二元平衡”和“三足鼎立”三种股权结构下股东间合作机制的类型和主要特征．分析说明股东间合作机制与公司绩效间的关系。研究发现，股东间的合作是由经济因素、制度因素、情感与行为因素共同决定的，是一种动态的均衡状态。股东间高效的情感交换能够在一定程度上对经济交换产生替代作用，对信任有一定的正向调节作用。股东间合作机制对公司绩效的影响同时受到联合持股比例、股权集中度、股权流动性、股权制衡度和公司治理环境的约束。

英文摘要：

There are serious defects in the previous studies on cooperation mechanism among the shareholders. Firstly, the former studies didn＇t systematacially explain and analyze cooperation mechanism among the shareholders. Secondly, the hypothesis of the ＂economic man＂ is not conforming to the multiple human nature in the real world, which causes the poor explanatory power and applicability. Thirdly, in the previous studies, the scholars merely focused on the cooperation among the large shareholders and ignored the functions of the minority shareholders in corporate governance. Based on the comprehensive consideration of the hypothesis of human nature such as ＂economic man＂, ＂social man＂ and ＂complex man＂, we build a cooperation model among the shareholders which determined by the factors of economic, institution, emotion and behavior, and systemataciaUy explain the building mechanism of cooperation mechanism among the shareholders. According to the shareholding structure of the listed companies in China, we propose and discuss the patterns and characteristics of shareholders＇ cooperation under three shareholding structures named ＂one single - large shareholder＂ , ＂ binary equilibrium ＂ and ＂tripartite confrontation＂, and explore the relation ship between the cooperation mechanism among the shareholders and the corporate performance. We argue the cooperation among the shareholders decided by economical, institutional, emotional and behavioral factors together and is a dynamic balance. Simultaneously, the highly effective emotional exchange among the shareholders plays a substitute role in economic exchange and positively adjusts the trust. The influence of the cooperation mechanism among the shareholders to the corporate performance will be affected by joint ownership, ownership concentration, ownership liquidity, outside blockholders and governance environment- together.
