摘　　要： 大股东是公司治理的重要参与主体,但大股东行为未必都是理性的。本文以大股东增持为研究的切入点,研究了大股东过度自信行为对公司治理有效性的影响。结果发现,大股东过度自信行为对公司治理有效性有显著的负面影响,而公司外部治理环境的完善对其具有矫正作用。即使剔除政府救市因素对大股东增持的影响,上述研究结论也依然成立。本文认为,在公司治理机制构建中对参与主体非理性因素的考虑,是提高公司治理机制有效性的重要前提。 Major shareholders make important influence in corporate governance, but their behavior is not always rational. This paper examines the relationship between major shareholders overconfident behavior and corporate governance efficiency by studying their holding increase. The results show that there is significant negative influence of major holders＇ overconfident behavior on corporate governance efficiency, while perfect exterior corporate governance can remedy it. Even though the influence of government is eliminated, the conclusions are still valid. Therefore, we believe it an important prerequisite for enhancing corporate governance efficiency to consider the irrational behaviors of major shareholders.
