Abstract: For a two-tier supply chain system consists of manufacturer and suppliers,cooperation mecha-nism between bounded rational manufacturer and suppliers through long-term collaborative product developmentis studied on the basis of evolutionary game theory.Firstly,cost and income allocation mechanisms are analyzed; then,supervision and punishment mechanism is explored.Through the analysis of equilibriumresults and data simulation,result shows,the probability of cooperation of both sides has a positive correlation with excess income of cooperation and independent product development,and a negative correlation with total cost of development and betrayal income; there is an optimal proportion of excess income allocation that maximizes the probability of cooperation; cost shared by both sides is positively related to the excess income they obtaine; under the condition of supervision,reasonable punishment will effectively reduce betrayal.

Key words: supply chain, collaborative product development, cost allocation, income allocation, punishment mechanism, evolutionary game
