摘　　要：针对再制造成本不确定条件下考虑制造商风险规避特性的新产品与再制造产品差别定价协调问题,采用均值—方差方法衡量该问题的最优定价决策。在分散化决策下,采用Stackelberg博弈理论研究价格差敏感系数和制造商风险规避度对闭环供应链定价策略的影响,然后以集中化决策作为研究基准,指出分散化决策存在双重边际效应。为消除利益损失,提出一种收益共享一风险共担契约来协调闭环供应链,研究表明,该协调契约能有效实现风险规避下闭环供应链的协调。最后运用数值分析方法对无协调和有协调时的闭环供应链定价策略进行比较研究,并进一步探讨价格差敏感系数和制造商风险规避度对闭环供应链定价策略以及协调性能的影响。Aiming at a coordination and differential pricing strategy between new and remanufacturing products with a risk aversion manufacturer, under remanufacturing cost uncertainty, this paper proposed the method mean-variance to analyze the optimal pricing strategy of the problem. It proposed tht~ Stackelberg game theory to research the effect of price differential sen- sitivity coefficient and risk aversion degree for closed-loop supply chain pricing strategy under the decentralized decision-mak- ing. Then the centralized decision-making regarded as the benchmark, pointed out that the double marginalization exists in de- centralized decision-making. To eliminate the loss of profits, this paper proposed a revenue sharing-risk pooling contract to co- ordinate the closed-loop supply chain.. Research shows that the coordination contract can effectively realize coordination of closed-loop supply chain with risk aversion. Finally, it applied a numerical analysis method to comparative study closed-loop supply chain pricing strategy with non-coordination and coordination conditions, and to further explore the effect of price differ- ential sensitivity coefficient and risk aversion degree for pricing strategy and coordination of closed loop supply chain.
