lo reveal the influence of extended producer responsibility(EPR)and consumer trust preference on the decisions of members in a closed-loop supply chain,this paper establishes a Stackelberg game model involving the manufacturer,the retailer,the recycling alliance,and a third-party recycler to investigate the recycling decision of wasted electronics under three modes:independent recycling of the manufacturer without EPR,alliance recycling,and third-party recycling with EPR.The results show that the degree of consumer trust preference is positively related to the profit of the supply chain and the social welfare with EPR.Further,the difference between the profit of retailer and manufacturer decreases with consumer trust preference,and the profit of supply chain is higher in the alliance recycling mode than in the third-party recycling mode with EPR.The social welfare in both EPR modes is greater than in no-EPR mode.The optimal recycling strategy of the manufacturer achieves the maximum social welfare in all the three modes.Therefore,the government should provide incentives for the manufacturer to implement alliance recycling through EPR,and induce consumers to participate in EPR practice,so as to achieve a balance between EPR and consumer trust preference in guiding firms'recycling behavior.
