Abstract: At present, some research on incentive mechanism has started in the knowledge transfer within supply chain, but usually only considering the incentive to the knowledge supplier and ignoring the supervision to the knowledge supplier, which limits the incentive effect. In order to solve this problem, the mathematical modeling and computer simulation analysis methods are used. By introducing the supervisory signal, the knowledge transfer incentive models among the members of the supply chain are established on the basis of the basic incentive models of knowledge transfer among the members of the supply chain. It is found that the income level and transfer efficiency of knowledge transfer within the supply chain have been improved by using supervisory signals, but the income level and transfer efficiency of knowledge transfer between the upper and lower members of the supply chain are higher and more profitable than those of the same level members. The research results can provide practical guidance for supply chain enterprises to effectively carry out knowledge transfer activities and enhance the competitiveness of supply chain.
