Abstract: Efficient incentive mechanisms can exert knowledge-employees’ more creativeness for the knowledge-firms.Under the conditions of the two-stage information asymmetry of value creation and value-addition distribution within the process of firms’sustainable growth,this paper analyzes the Stackelberg game between firm and knowledge-employee,and addresses the mechanism and value-addition distribution of the co-op game behavior in virtue of the evolutionary process of the fully co-op model.The result suggests that the short-run incentive is significantly complementary with the long-run one,and to adjust properly the level of the two can maximize the systematic income of the firm.How to allot firm systematic premiums is further researched,and it is argued that knowledge-employees’risk attitude and position significantly influence the incentive effort.
