摘要： 本文利用2003-2009年有机构持股的A股上市公司为样本,基于不同的企业产权,利用两阶段最小二乘模型研究了不同类型的机构投资者在股改前、股改中对公司绩效的影响。首先讨论了以基金为代表的国内机构投资者和合格境外机构投资者(QFII)与公司绩效的关系,发现基金持股与公司绩效之间存在显著的正向关系,表明基金持股有助于提高公司绩效,而QFII对我国上市公司绩效没有影响。然后,研究了股权分置改革对机构持股与上市公司绩效关系的影响,以及股权分置改革前后,产权性质对机构持股与上市公司绩效关系的影响。结果显示,国有产权性质和股改过程这两个因素对以基金为首的国内机构投资者在提高公司绩效方面有不利影响,而对还未介入我国上市公司治理的QFII的投资行为没有明显影响。
