第三方负责回收的闭环供应链差别定价协调契约设计

摘要

Based on the game theory, the differential price coordination is addressed in this paper for a closed-loop supply chain with third-party collection of used products. First, the decentralized and centralized differential pricing models are established. With them, the optimal pricing strategy and the optimal profit for the members in a closed-loop supply chain are analyzed. Then,it is found that efficiency is lost in the decentralized closed-loop supply chain. Finally,it puts forward a profit-sharing coordination contract to coordinate the closed-loop supply chain, which makes the profit of the decentralized closed-loop supply chain equal to that of the integrated closed-loop supply chain.%以博弈论为基本研究方法,研究了第三方负责回收的闭环供应链系统差别定价协调契约的设计问题.构建了三方非合作分散决策情形和合作集中决策情形下的系统差别定价模型,分析得到了两种情形下闭环供应链系统成员的最优定价策略和利润,发现三方分散决策会造成系统效率的损失.由此,提出了一种收益分享协调契约,实现了闭环供应链系统的协调,并使供应链系统整体利润达到集中决策时的利润水平.
