中文摘要：

伴随着电子商务技术与服务的快速发展,低成本高回收的商品回收模式成为投资者和学者研究的热点。以在线零售商为研究主体,针对废旧零部件的循环再利用,充分考虑消费者在零售商回收过程中的角色,讨论了三种回收策略情况,即两阶段回收策略、竞争型回收策略以及＂合作型＂回收策略。通过考察这三种策略中在线零售商的最优利润以及供应链总利润等变量的变化情况,为在线零售商实施合适的逆回收策略提供依据。研究结果表明：回收策略不同,在线零售商、消费者以及整个供应链的利润不同;在线零售商及供应链总利润受利益共享比例以及消费者参与方式的影响。进而通过仿真分析为在线零售商根据自身实际情况实施废旧零部件的回收策略提供参考依据。

英文摘要：

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.
