生产者责任延伸制下销售一回收型闭环供应链收益共享契约研究

针对由单个制造商和单个销售商所组成的销售－回收型闭环供应链，在生产者延伸责任（ EPR）制度下，制造商委托销售商销售产品，同时制造商承担实施EPR制度的成本。考虑产品的销量、回收量均受实施EPR制成本影响的基础上，从最大化供应链利润和最大化EPR绩效水平两个视角设计收益共享协调契约，该收益共享契约能实现两个视角下闭环供应链的协调，有助于供应链成员在实施EPR制度的同时提高利润，从而激励供应链成员实施EPR制度，积极参与废旧品的回收。

Research on Revenue-sharing Contract of Sales-recycling Closed-loop Supply Chain with EPR

This paper studied the sales-poor closed-loop supply chain composed of a single manu-facturer and retailer.Under the EPR ( extended producer responsibility) system, the manufactur-er entrusts retailer sel ing products, at the same time, the cost of implement EPR system by manufacturer.on the basis of exploration of the effects the members of supply chain have on the sales and return volume by implementing EPR system, design revenue sharing contract from maximizing supply chain profit and the EPR performance level.This contract can achieve two per-spective of closed-loop supply chain coordination, make the members of the supply chain in the EPR system increase profits simultaneously.Meanwhile, it can also facilitate the supply chain to raise the level of implementing EPR and stimulate its members to return end of use products and end of life products.
