摘　　要：针对供应链合作的新模式,构建基于担保销量的单期两级供应链期权契约模型,并将决策者风险偏好引入决策模型,利用Pratt-Arrow绝对风险厌恶度对合作中所转移的风险成本进行了刻画,以此修正供应商和销售商的决策效用函数。研究得出了供应商购买的最优担保销量以及最优生产批量,并分析了最优担保销量存在的条件和销售商的最优风险溢价系数所满足的条件。论证了考虑决策风险偏好的期权销量担保契约在产品的生产批量安排上能够实现供应链协调。最后通过案例验证了本文的研究结论。A model of sale-surety contract is constructed for the new mode of the supply chain coordination. Decision-making risk preference is put into the model, and then the risk cost is measured with the coefficient of Pratt-Arrow risk aversion to modify the supplier＇s utility function and retailer＇s one. First, the supplier＇s response function of sale-surety quantity and optimal product quantity are gained and then the existence of sale-surety quantity is discussed. Second, the conditions that the coefficient of optimal risk premium should meet are shown. Third, the paper proves that the sale-surety contract could make the supply chain coordinate. In the end, the paper＇s conclusion is verified by case analysis.
