By selecting index system which reflects the listed companies’ performance and managers’ endeavor degree, a linear regression model was constructed. The correlativity between the listed companies’ performance and managers’ rewards was analyzed through software SPSS15.0. The results show that there is no significant relativity between managers’ reward and the listed companies’ performance, and between the companies’ size and managers’ share proportion. While the managers’ annual reward or share proportion tends to be low, the incentive mechanism will suffer a lot from it.
