政府补贴下闭环供应链差别定价及协调机制

Research on the Differential Pricing and Coordination Mechanism of Closed-Loop Supply Chain under the Government Subsidy Policy

基于不同的补贴模式——政府补贴制造商(GM模式)、政府补贴零售商(GR模式),分别建立差别定价下的集中式与分散式闭环供应链决策模型,研究政府补贴下新产品与再制品差别定价的闭环供应链决策及协调机制问题。研究结果表明:制造商在GR模式下会相应提高再制品的批发价格,且与GM模式下批发价格的差额为单位再制品的政府补贴;针对分散式决策闭环供应链的"双重边际问题",构建基于数量折扣和收益共享契约的协调模型,通过确定两种协调机制下的契约比例,能实现闭环供应链的协调。

To study the decision-making and coordination mechanism of closed-loop supply chain under government subsidy policy and price discrimination between new and re-manufactured products,the centralized and decentralized closed-loop supply chain models under the differential pricing were established based on different government subsidy policies,which are government subsidies the manufacture(GM mode)and subsidies the retailer(GR mode)respectively.The results illustrate that the manufacturers will increase the wholesale price of re-manufactured product under the GR mode,and the wholesale price margin is the government unit subsidy compared to the GM mode.To solve the double marginalization effect problem of decentralized closed-loop supply chain,the quantity-discount and revenue-sharing contract were constructed,and the coordination of decentralized closed-loop supply chain was realized by determining the ratio of the two contracts.
