A lot of scholars often laid particular emphasis on the study of the relationship of managing the characteristic of directorate and performance of the company in the past research and seldom involve the question of CEO Turnover. This text has done the very important one in this respect supplementarily. And it has introduced the new variable such as company's scale, general manager's age, and big shareholder's shareholding ratio. Also adopt relative EPS and relative ROE two kinds of performance indexes at the same time to weigh the management state of the company.
