中文摘要：

运用博弈理论在混合回收的情形下建立了再制造闭环供应链模型。首先,在分散化定价决策下研究了闭环供应链中的节点企业为了取得各自最优利润,如何确定自己的批发价、零售价、废旧品的回收价和回收补贴价格,以及分析了混合回收所带来的竞争和冲突对节点企业定价决策和利润的影响。然后,以集中化定价决策下的均衡结果作为基准,指出分散化定价决策将导致一定的效率损失。最后,为弥补效率损失,提出了一个改进的两部定价契约来实现闭环供应链的协调。

英文摘要：

Based on game theory,this paper discusses in a closed-loop supply chain how the manufacturer and the retailer make their price decision regarding wholesale price,retail price,collection price and recovery subsidies price when the manufacturer and the retailer both collect used products under hybrid recovery channel.It is indicated that the system profit in the decentralized closed-loop supply chain is less than that in the centralized closed-loop supply chain.Therefore,a modified two-part pricing contract is presented to coordinate the closed-loop supply chain.
