股权结构、公司绩效与股权改革——基于我国IT行业上市公司的实证分析Ownership Structure,Corporate Performance and Ownership Reform:an Empirical Research on Chinese Listed Companies of IT Industry
周昌仕
摘要(Abstract)：
以信息技术行业76家上市公司为样本,利用主成分分析构建综合绩效变量,并回归分析了股权结构与公司绩效的相关关系。结果表明,公司绩效与股权结构并无显著相关性。尽管股权改革可以降低“遂道效应”,保护中小股东的合法利益,维护资本市场的公正性和长效发展,但并不能从根本上改变上市公司现有绩效状况。增强公司在产品市场上的核心竞争力,充分发挥控制权市场收购功能,才是提高上市公司绩效的根本途径。
