Abstract: With the rapid development of e-commerce technologies and services, products of low cost and high recovery model become research hot spots of investors and academics. This paper takes online retailers as the research subject, and considering the recycling of scrap parts and the role of consumer in the retailer recycling process, it discusses three recovery strategies, namely the two-stage recovery strategy, competitive strategy, and the recovery of " cooperative” recovery strategy. By examining the three strategies, including changes in the optimal profit online retailers as well as the total supply chain profits and other variables, it provides evidence for online retailers to implement appropriate reverse recoverty policies. The results show that: different recovery strategies lead to different profits of online retailers, consumers and the entire supply chain; the profit of of online retailers and supply chain rely on benefit-sharing ratio of the total profits and the impact of participation of consumers. Furthermore, through the simulation analysis based on their own actual situation, it provides the reference basis for an online retailer to adopt recycling strategies of scrap parts.
