中文摘要：

研究了集中式和分散式决策的三种渠道权力结构下闭环供应链的定价问题,比较各种情况下定价和利润的差异,并运用二部定价契约探讨了不同渠道权力结构下闭环供应链的协调方法。研究表明：MS与RS情形下闭环供应链的总利润相同且低于VN情形;随着产品替代系数的增加,新制造和再制造产品的价格均提高,制造商和零售商的利润均增加;随着回收努力程度的提高,两种产品的价格均提高,而制造商和零售商的利润均减少;运用二部定价契约可通过主导方或借助第三方有效协调闭环供应链。

英文摘要：

This paper studies the pricing problem of closed-loop supply chains under three channel power structures,the pricing and profits are compared,and the two-part tariff contract is applied to discuss the coordination of closed-loop supply chains.The results show that the total profit of closed-loop supply chain under the case MS is the same as the profit under the case RS,and they both are lower than the profit under the case VN.The prices of the new and remanufactured products and the profit of the manufacturer and the retailer increase with the increase of the substitution coefficient.The prices of the new and remanufactured products increase with the increasing of collection effort,but the profit of the manufacturer and the retailer decreases as the increasing of collection effort.The two-part tariff contract is appropriate to coordinate closed-loop supply chains through the leader part or the third part.
