摘要: 本文采用中国A股2008—2015年上市公司的数据,考察了上市公司的反收购条款如何影响股价同步性,进而影响公司的投资效率。实证结果首先表明,公司的反收购条款越多,股价同步性就越高,投资效率也就越低。也就是说,反收购条款会通过减少股价信息对公司的反馈作用而降低投资效率。然后本文再分别按照股权集中度和实际控制人性质分组比较后发现,反收购条款的上述作用在股权集中度低、民营企业中更大。

Furthermore, according to the comparison of the concentration of ownership and the nature of the actual controller, it is found that the above-mentioned role of the anti-takeover clauses is lower in the concentration of the stock, and the private enterprise is bigger.
