英文摘要：

Based on Upper Echelons Perspective, key problems of previous researches on CEO succession are studied to analyze relationship among ST listed enterprises＇ new CEO characteristics, TMT adjustment and enterprise performance changes. We choose 110 CEO succession samples from listed enterprises which replace CEO from 2000 to 2010 are chosen in the empirical research,and it can be found that new CEO age and education level have significant positive effects on enterprise short-term performance changes. New CEO without working experience as CEO can better improve short-term performance than the CEO with relevant experience. New CEO from internal can better improve long-term performance than CEO from ex- ternal. TMT adjustment has a significant positive effect on short-term performance changes, but new CEO＇s characteristics have no significant effect on TMT adjustment. This study provides a new perspec- tive for researches about transformation strategy of performance declined enterprises, and also provides a basis for Chinese enterprises to select and replace CEO.
