In order to improve the issues that excessive reliance on government physical reserves can lead to high sunk costs when no emergencies occur or high emergency procurement costs due to insufficient supplies. Firstly, the option contract was introduced to construct a hybrid reserve decision-making model for emergency supplies, incorporating social donations into the decision-making framework. Secondly, the selection of optimal hybrid reserve mode and allocation of reserve amount under the option contract mechanism were studied to minimize expected costs of the government. Then, the optimal decision based on the Karush-Kuhn-Tucker (KKT) conditions and optimal strategies were proposed. The standard implicit functions were obtained for the optimal amount of government physical reserves, contracted enterprise physical reserves, and contracted enterprise production capacity reserves. Finally, taking material donations and financial donations as the key channels for emergency supply provision. A sensitivity analysis and numerical simulations of related parameters were conducted. The effects of option contract premiums, disposal costs of donated materials, and the amount of material and fund donations on optimal reserve strategies and expected costs of the government were explored. The results indicate that the government may flexibly choose whether to execute contracts for reducing expected costs and expanding reserve scale. The increase in procurement costs in the spot market for emergency supplies enhances the sensitivity of expected costs of the government to changes in demand. The government should actively guide social forces to participate in emergency rescue and flexibly adjust donation strategies according to the intensity of emergencies.

为改善因过度依赖政府实物储备,在未发生突发事件时,造成高沉没成本或因物资不足造成高紧急采购成本的问题,首先引入期权契约,构建应急物资混合储备决策模型,并将社会捐赠纳入决策框架;然后研究期权契约机制下,考虑最小化政府期望成本,选择最优的混合储备模式和分配储备量,并提出最优决策的卡罗需-库恩-塔克(KKT)条件和最优策略,得出关于最优政府实物储备量、协议企业实物储备量和协议企业生产能力储备量的标准隐函数;最后将物资捐赠和资金捐赠作为应急物资供应的关键渠道,对相关参数进行敏感性分析和数值模拟,探讨期权契约权利金、捐赠物资处理成本、物资和资金捐赠量对最优储备策略及政府期望成本的影响。研究结果表明:政府可以灵活选择是否执行契约,降低期望成本并扩大储备规模;应急物资现货市场采购成本的增加会提高政府期望成本对需求量变化的敏感度;政府应积极引导社会力量参与应急救援,并根据突发事件的强度灵活调整捐赠策略。

为改善因过度依赖政府实物储备,在未发生突发事件时,造成高沉没成本或因物资不足造成高紧急采购成本的问题,首先引入期权契约,构建应急物资混合储备决策模型,并将社会捐赠纳入决策框架;然后研究期权契约机制下,考虑最小化政府期望成本,选择最优的混合储备模式和分配储备量,并提出最优决策的卡罗需-库恩-塔克(KKT)条件和最优策略,得出关于最优政府实物储备量、协议企业实物储备量和协议企业生产能力储备量的标准隐函数;最后将物资捐赠和资金捐赠作为应急物资供应的关键渠道,对相关参数进行敏感性分析和数值模拟,探讨期权契约权利金、捐赠物资处理成本、物资和资金捐赠量对最优储备策略及政府期望成本的影响。研究结果表明:政府可以灵活选择是否执行契约,降低期望成本并扩大储备规模;应急物资现货市场采购成本的增加会提高政府期望成本对需求量变化的敏感度;政府应积极引导社会力量参与应急救援,并根据突发事件的强度灵活调整捐赠策略。

In order to improve the issues that excessive reliance on government physical reserves can lead to high sunk costs when no emergencies occur or high emergency procurement costs due to insufficient supplies. Firstly, the option contract was introduced to construct a hybrid reserve decision-making model for emergency supplies, incorporating social donations into the decision-making framework. Secondly, the selection of optimal hybrid reserve mode and allocation of reserve amount under the option contract mechanism were studied to minimize expected costs of the government. Then, the optimal decision based on the Karush-Kuhn-Tucker (KKT) conditions and optimal strategies were proposed. The standard implicit functions were obtained for the optimal amount of government physical reserves, contracted enterprise physical reserves, and contracted enterprise production capacity reserves. Finally, taking material donations and financial donations as the key channels for emergency supply provision. A sensitivity analysis and numerical simulations of related parameters were conducted. The effects of option contract premiums, disposal costs of donated materials, and the amount of material and fund donations on optimal reserve strategies and expected costs of the government were explored. The results indicate that the government may flexibly choose whether to execute contracts for reducing expected costs and expanding reserve scale. The increase in procurement costs in the spot market for emergency supplies enhances the sensitivity of expected costs of the government to changes in demand. The government should actively guide social forces to participate in emergency rescue and flexibly adjust donation strategies according to the intensity of emergencies.
