摘　　要：全球突发事件冲击供应链而引发的少供甚至断供现象近年频发,供应中断风险极大影响整个供应链的健康平稳运行。为减少供应中断损失,优化采购策略,本文基于供应商、制造商及顾客形成的二级供应链结构,构建了单源和双源采购策略模型,通过Stackelberg博弈逆向求解,得到单双源采购策略模型下各主体最优决策。研究发现供应商和制造商以自身利润最大化,分别决定最优供应价格和最优订购量,相较单源采购策略,采取双源采购策略有利于促进上游供应商提高供应可靠度和降低产品价格以相互竞争,从而提高制造商和供应链整体最优利润。The phenomenon of supply shortage or even supply interruption caused by global emergencies impacting the supply chain has occurred frequently, and the risk of supply interruption has greatly affected the healthy and stable operation of the entire supply chain. In order to reduce the loss of supply interruption and optimize the procurement strategy, this paper constructs a single- source and dual-source procurement strategy model based on two-tier supply chain structure formed by suppliers, manufacturer and customers, and obtains the optimal decision of each subject through the reverse solution of the Stackelberg model. The study finds that suppliers and manufacturers maximize their own profits by determining the optimal supply price and the optimal order quantity, respectively. Compared with the single-source procurement strategy, the dual-source procurement strategy is conducive to promoting upstream suppliers to improve supply reliability and reduce product prices to compete with each other, thereby improving the optimal profit of manufacturer and supply chains as a whole.
