Abstract: When the tide of large-scale used products begins to emerge, how to recycle these used products rationally? The development of remanufacturing industry can alleviate many problems caused by the heavy environmental load caused by a large number of used products. In order to encourage consumers to buy remanufactured product, the game models of the closed-loop supply chain with manufacturers, recyclers, consumers and governments which provides subsidy to consumer are constructed. Using the game theory, the optimal solutions of the models are obtained. The impacts of the government subsidy to consumer on supply chain profit, customer surplus, welfare of the whole society are discussed in this paper. The results indicate: (1) when the certain condition is sufficient, the government needs to provide the subsidy to consumer; (2) the government subsidy to consumer is distributed equally between manufacturer and consumers; (3) the supply chain profit, consumer surplus, welfare of the whole society can be improved by the government consumption-subsidy policy; (4) it would be better to improve the recovery rate of the CLSC if the recycling of used products would be done by the third-party recyclers;(5) the remanufactured product cannibilizes the market of new product when government offering the consumption-subsidy. At last, the conclusions of the models are verified by numerical examples. The contribution of this paper lies in not only consider the government consumption subsidies as endogenous variable and based on the perspective of consumer subsidies, to explore the presence of consumer subsidies policy effect, The results of the study can enrich the theory of closed-loop supply chain management and provide decision-making reference for related department of government and enterprise, promote the enterprise sustainable development.
