Remanufacturing product sales of the difficulties faced on the closed-loop supply chain and old product recycling and difficult problems, improve the efficiency of the operation of closed-loop supply chain, this paper studies using Stackelberg game method, and considering the retailer for remanufacturing product marketing efforts and recyclers of recycling of waste products and coordinate efforts of closed-loop supply chain pricing contract. The results show that only the retail price of remanufactured products is affected by the level of marketing effort and the repurchase price of used products is affected by the level of recycling effort. The sensitivity of marketing effort level has a inhibiting effect on the demand for new products, while the cost coefficient has a promoting effect on the demand for new products, and the effect on the remanufactured products is just the opposite. Pareto improvement of the whole supply chain can be achieved by using revenue sharing and cost sharing contracts.
