| 摘 要： | 总经理变更是公司内部治理的重要手段,其业绩敏感性受到多种因素的影响,以2002年～2007年沪深两市702家A股上市公司的数据为样本,探讨多元化经营对总经理变更绩效敏感性及其业绩改进效应的影响,为公司经营模式对公司治理效率的影响提供经验证据,利用传统的Logistic回归、边际效应分析以及面板数据随机效应回归对多元化和总经理变更的关系进行研究。实证结果表明,多元化降低了总经理变更的业绩敏感性,多元化公司总经理变更的概率与资产收益率代表的多元化公司业绩变化没有显著的关系,即使在公司业绩下降的条件下,股东替换总经理的动机也弱于集中化公司;多元化公司总经理变更后的资产重组行为规模显著弱于集中化公司,带来的业绩改进也小于集中化公司。
