摘　　要：为提高社会化应急物资联合储备模式的适用性和拓展性、降低政府和制造商的储备风险,引入原材料供应商构建数量柔性契约下政府主导的Stackelberg政企三级联合储备模型。在该模型中,政府和制造商共同储备应急物资的实物,而供应商则负责储备生产应急物资的原材料。使用博弈论中逆序求解法分析政企三方各自的最优储备量,均衡状态下的期望利润和期望成本;并与政府单独储备模式进行对比,以评估政企三级供应链的优势;最后,通过数值模拟和敏感性分析的方法验证结论。研究结果表明:特定的市场条件下,政企三级联合储备模式不仅能够提高整体应急物资储备量,也可降低政府储存风险,提高企业利润,还可强化应急物资储备系统的结构和效能。To improve the applicability and scalability of the joint reserve model for social emergency supplies,and reduce the reserve risks of the government and manufacturers,raw material suppliers were used to propose a government-led Stackelberg three-tier joint reserve model of government and enterprises under a quantity flexibility contract.In this model,the government and manufacturer engaged in joint a stockpile of physical emergency supplies,while the suppliers were responsible for stockpiling raw materials for the production of emergency supplies.The inverse-order solution method in game theory was used to analyze the optimal reserve quantity of the three parties to balance the expected profit and cost.Moreover,the advantages of the proposed three-tier supply chain model involving government and enterprises were evaluated.Finally,the model performance was validated by numerical simulation and sensitivity analysis.The results demonstrated that the three-tier joint government-enterprise stockpile model not only improved the overall emergency stockpile volume under specific market conditions but also reduced the government's storage risk.Furthermore,it can enhance the profitability of high-performing enterprises and reinforce the structure and efficacy of the emergency stockpile system.
