Game theory was used to develop the model of a closedloop supply chain system including one manufacturer and one retailer.The impacts of consumer approval and recycling remanufacturing cost on product sale and supply chain performance were analysed under different degrees of product difference existing in decentralized structure.The result shows that in the case of very high consumer approval,recycling remanufacturing is an important strategic option; in the case of very low consumer approval,rational choice is leave recycling remanufacturing out of account; and in the case of middle consumer approval,product remanufacturing depends on recycling and remanufacturing cost.
