中文摘要：

在销售渠道和回收渠道均存在冲突的情形下建立了闭环供应链博弈模型．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，以及分析了销售渠道冲突和回收渠道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，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，以弥补分散化决策的效率损失．最后，运用算例的方法，进一步分析和讨论了渠道冲突对闭环供应链定价决策、制造商和零售商收益比，以及闭环供应链渠道运作效率的影响．

英文摘要：

Based on game theory, this paper discusses in a closed-loop supply chain （CLSC）. How the manu- facturer and the retailer make their price decision including the wholesale price, retail price, collection price and recovery subsidies price when the Manufacturer and the Retailer both sell sales new products and collects used products under hybrid marketing and recovery channels. It＇ s indicated that the system＇ s profit in the de- centralized 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. The effect of channel competition and conflict on pricing decision of CLSC, the division of the channel profit, and the efficiency of the CLSC system are also studied by using numerical study method.
