The closed-loop supply chain extends the product life cycle to a certain extent and has the characteristics of saving resources and reducing pollution.Therefore,it has become an important way for most countries to realize sustainable development.With the concept of "energy saving and emission reduction","low carbon economy" and other concepts put forward and spread,the recycling and remanufacturing of waste electronic products has gradually attracted the attention of the government and the society. In general, In the same type of electronic products closed-loop supply chain,there are a number of manufacturers and retailers.the retailers will be responsible for the recycled products, manufacturers use waste products to reduce the raw materials’ cost and manufacturing cost to improve their gross income.therefore,manufacturers will compete with each other in order to get more number of recyclables That creates competition among manufacturers for recycled products. Based on the above background,on the basis of reading and understanding the research literature related to recycling and remanufacturing closed-loop supply chain and mastering the stackberg game.Taking the recycling and remanufacturing closed-loop supply chain as its background,a remanufacturing closed-loop supply chain consisting of two manufacturers and one retailer is established.Supposing the respective efforts of the two manufacturers affect the total amount of Recycled products in the market,and retailers independently determine the distribution ratio of recycled products between manufacturer 1 and manufacturer 2.The behavior analysis of manufacturer 1,manufacturer 2 and retailers is carried out based on the stackberg game and then Obtaining the optimal decision of each subject When only thinking about their own benefits.
