董事会治理评价、治理指数与公司绩效实证研究

在优化中国上市公司董事会治理评价指标体系的基础上,对上市公司董事会治理状况进行指数化评价,并对董事会治理评价指数及其与公司绩效的关系进行实证分析.实证结果显示,董事会治理质量趋于改善,独立性有所增强,但整体治理指数仍然较低;行业因素、控股股东性质对董事会治理产生重要影响,即行业的竞争性越强董事会治理质量越高,当控股股东为职工持股会和民营企业时董事会治理指数较高;不同董事会治理机制间存在替代效应,董事会治理水平的提高对公司绩效产生显著的正向效应,由于替代效应的存在,单一董事会治理机制与公司绩效间的关系缺乏显著性和一致性,但作为一个整体,董事会治理质量的改善显著地提高公司绩效.据此提出改善中国上市公司董事会治理的政策建议.
