英文摘要：

This paper is focused on the issue of non-homogeneous team employee incentive, where the help of employees are considered. Two models, namely different incentive coefficients and the same incentive coefficient for non-homogeneous employees are proposed, respectively. By combining the staff incentive and team incentive, the synergistic effect and team sharing is introduced in the model formulation. Meanwhile, both material and immaterial incentive are applied in the modeling. The effect of base salary, performance salary, synergistic effect and team sharing on team cooperation are studied. The results indicate that the base salary has no effect on both the team performance and employee performance. Under the mechanism, the performance salary can not only inspire employees to work hard, but inspire team cooperation as well. The cooperation degree of team member is increased in the synergistic effect. Numerical examples are presented to illustrate the effectiveness of the proposed model. The effects of staff＇s ability, risk aversion,the uncertainty of output on the efforts of the staffs and the enterprise＇ s profits are analyzed. It indicates that applying the same incentive stratedy to the non-homogeneous employees is preferred when the difference between them is not significant. On the staff＇s ability is quite different, distinct strategies should be used.
