协议企业代储模式下应急物资储备策略及采购定价研究

应急物资企业代储是政府提高应急物资储备水平,保障物资供应能力的有效途径之一.在这一储备模式下,企业的物资储备方式选择(实物储备和生产能力储备)与对应储备量,以及政府的采购定价是最为核心的三个问题.为此,文章基于数量柔性契约构建了一个应急物资协议企业代储模型,并对该模型下的企业储备决策及政府采购定价问题进行了研究.在给出政企双方各自的最优决策后,文章发现储备周期内灾害事件的发生概率以及现货市场采购价格对双方决策具有重大影响,并进一步分析了这两因素对政府采购成本及企业利润的影响,从而为政企双方开展应急物资的储备合作提供了科学的指导依据.最后,文章通过数值模拟的方式对所得结论进行了验证.

Research on emergency supplies reserve strategy and procurement pricing under agreement enterprise reserve

Agreement enterprise reserve mode is one of the effective ways for governments to improve the level of emergency supplies reserve and ensure the supply capacity. In this reserve model, the choice of reserve methods (physical reserves and production capacity reserves), the corresponding quantity of emergency supplies and government procurement pricing are the three core issues. Therefore, based on a quantity flexible contract, the paper constructs a model of emergency supplies stored by agreement enterprises, and studies the corresponding reserve decision and procurement pricing. After giving the optimal decision of both parties, the paper finds that the probability of sudden disasters in the reserve cycle and the spot market price have important influences on the decision-making of both parties, and further analyzes the impact of these factors on the government's cost and enterprise's profit, which can provide scientific guidance and basis for the cooperation between governments and enterprises to carry out the emergency supplies reserve. Finally, the paper verifies the conclusions by numerical simulation.
