The effects of government subsidy policies are explored on the profits of each and overall supply chain members in different mixed recycling modes.The Stackelberg game model is established.The changes in the profits of each members and overall supply chain members are compared and analyzed with different recycling modes.And the numerical simulation analysis is conducted.It is pointed out that increasing the amount of government subsidy can increase the profits of each recycling entity and the overall supply chain profits in the optimal recycling mode,and the optimal recycling model for the closed-loop supply chain is obtained.The countermeasures and suggestions are proposed,such as increasing subsidy amounts,enhancing publicity and education,improving subsidy mechanisms,and building industrial clusters,etc.Theoretical basis and reference are provided for decision-making on the recycling model of the closed-loop supply chain.
