摘　　要：文章应用博弈论探讨了需求和回收均为随机情形下,分散决策系统和集中决策系统中产品的定价策略,提出收益费用共享契约,实现了供应链的协调,利用数值仿真分析研究了回收不确定性对供应链中各成员的定价、订货策略及利润的影响。研究结果表明:在面对产品回收市场行情波动性增大情况下,第三方物流服务商可以通过提高回收价格成功转嫁市场风险;分散决策模型中存在着双重边际效应;集中决策有利于抵御市场风险。In this paper ,the game theory is applied to studying the product pricing strategies of decen-tralized and centralized decision w hen the demand and collection is uncertain .T hen a revenue-and-ex-pense sharing contract is presented to keep balance of the supply chain .Finally ,the influence of un-certain collection on the pricing ,ordering strategies and profit of each member in the supply chain is studied by using numerical simulation .Some important management implications are acquired ：w hen facing the increasing volatility of recycling market ,the third party logistics can transfer market risk successfully by raising the recycling price ;there is a double marginal effect in decentralized decision ;centralized decision is beneficial to resisting market risk .
