中文摘要：

笔者通过对我国上市公司样本的实证分析,发现控制权结构与企业绩效之间存在显著内生性关系。在控制内生性影响以后,控制权结构与企业绩效负相关,公司控制权的分散有利于提升企业绩效;同时,企业绩效水平的提高对控制权的制衡也有很强的反馈作用。研究还发现,在中国资本市场,托宾Q值作为绩效评价指标比盈力能力更有效。

英文摘要：

An empirical analysis is made to investigate the relationship between control structure and firm performance. A severe endogenous in the relationship between the two variabl is found. In the case of the endogeneity, the coefficient of the two variables is much higher. Control decentralization is positive to upgrade firm performance. Meanwhile, the performance improvement in turn works for control balance. Tobin’s Q is a more accurate measure of performance index than profitability.
