Abstract:According to the reciprocal preference theory, the knowledge sharing incentive model of project team with two agents was established by introducing the conflicts of the effort of work and knowledge sharing. Thus an analysis was made of the influence of reciprocal preference on effort of knowledge sharing, effort of working, team expected utility and the incentive level of knowledge sharing, and then the related digital simulation was presented to prove the model theoretical analysis conclusions. The results show that when considering the influence of the work conflict, the role of reciprocal preference on effort of working, knowledge sharing incentive, team expected utility and soon are not absolutely active. However, it may improve the effort level of knowledge sharing.
