摘　　要：结合合约设计分析混合分销渠道结构下的两级供应链库存策略优化问题,是我们研究的重点。首先,通过构建模型,比较分析了线性转移支付合约和收益共享合约在实现供应链协调及收益分配方面的功能差异;其次,通过数值分析探讨了市场需求不确定性下模型的变化规律;最后得出管理启示,线性转移支付合约模型在实现供应链库存协调和Pareto改进上功能显著,却不能合理分配供需双方的收益,随着市场需求风险增加,生产商将提高零售商最低销售量,零售商将增加最优库存量;收益共享合约在合理分配供需双方收益上功能显著,但供应链整体收益处于次优状态,生产商分享的收益越多,零售商的最优库存量随市场需求风险增加而递减的速度就越快。This paper is concerned with a one-supplier-one-retailer supply chain stocking optimization in hybrid distribution systems. Firstly, we build three models and differentiate their functions of both the linear transfer payment contract model and revenue sharing contract model in SC stocking coordination and revenue sharing; Secondly, by numerical experiments, we find the models＇ operational laws under demand uncertainty; Finally, we conclude that, the linear transfer payment contract model plays an important role in SC stocking coordination and its＇ Pareto efficiency, however, it cannot solve revenue sharing better. As increasing demand risks, supplier will increase the lease sales scale and retailer will increase the optimal stocking quantities. On the other hand, the revenue sharing contract model plays an important role in revenue sharing, but the total revenues of SC are not optimal, the more revenues supplier shares, the faster retailer＇s optimal stocking quantities step-down speed as increasing demand risks.
