使用中国A股市场2001~2006年的所有A股非金融类上市公司为初始样本,从公司股权结构两个维度即股权集中度和股权性质的角度来分析其对公司过度投资水平的影响,得出以下结论:第一大股东的持股比例与企业过度投资水平之间正相关关系,而且呈倒U型关系;第二大股东在抑制大股东投资冲动方面发挥了治理效率,起到了一定的股权制衡作用,但是整体上股权制衡抑制过度投资水平效果不好,反而有加剧投资水平的特征;与民营企业控股公司相比,在地方政府或地方国企控股的公司存在显著的过度投资问题,但是在中央国企控股和外资控股没有发现过度投资现象。这些证据为我国股权结构治理的改善和证券监管部门提供了新的思路。

This paper uses all a-share non-financial listed companies in China during 2001 to 2006 as initial samples to analyze how the two dimensions of the ownership structure affect over-investment of companies.The conclusions are as follows: there is a positive correlation between the share ratio of the largest shareholder and over-investment level,also inverted U-shaped correlation;the second largest shareholder plays a role in restraining over-investment impulse,but overall the ownership balance curbing over-investment is not good and on the contrary it has increased the level of investment;compared with the private-owned companies,local government-owned enterprises have significant over-investment problem,but there are no over-investment in central government-owned companies and foreign holding companies.These evidences provide a new idea to improve the governance of ownership structure and for the security regulators.
