中文摘要：

按分散式决策、集中式决策两种情形，分别构建了产品回收量与回收价格和回收努力同时相关的逆向供应链决策模型；并通过二部定价契约和回馈与惩罚契约对分散决策下的逆向供应链实现了协调，避免了“双重边际加价”所导致的利益损失，使得整条供应链的总利润与集中决策下的目标一致。

英文摘要：

This paper provides the reverse supply chain models under centralized structure and decentralized structure, in view of the fact that product quantity of returning dependent collection effort level and collection price simultaneously. Then the coordination of two-part tariff contract, and rebate and penalty contract are introduced to coordinate the reverse supply chain. Both of the coordinations aviod the profit loss from the reverse double marginalization, so that the total profit of the reverse supply chain is identical with the objective of system.
