应急物资政企联合储备合作机理研究

针对一些应急物资,采用政府企业联合储备方式储备,可以降低政府储备成本,企业也可以从中获益。本文研究政企联合实物储备的合作机理,分析了联盟参与人之间的博弈关系,建立了联盟收益模型,运用shapley值解决合作的联盟收益分配问题,最后分析了联盟的稳定性。算例分析显示在政企合作联盟中政府和企业关系类似“地主”和“农民”的关系,当企业获得的收益小于其机会成本时,企业不愿意加入联盟,这时政府需对企业进行交叉补贴来维持联盟稳定。缺货成本低于政府储备成本时,政府会考虑与企业联合储备或者选择缺货;缺货成本低于企业储备成本时,政府选择缺货。

The Study of Cooperation Mechanism between Government andEnterprises in Emergency Supplies Reserve

For some kind of emergency supplies, the joint of government and enterprises can reduce the cost of government, and the enterprises can also benefit from it. This paper studies the mechanism of cooperation between government and enterprises in emergency supplies reserve. First it analyses the game between the alliance participants; then it uses the shapley value to solve the revenue distribution problem in the alliance; finally it analyses the stability of the alliance. The example analysis shows that the relationship between the government and enterprises in the alliance is similar to the relationship between “landlords” and “peasants”; the enterprises are reluctant to join the alliance when the earnings they gain are less than their opportunity cost, the government needs to cross-subsidize enterprises to maintain the stability of the alliance. When the shortage cost is less than the cost of government reserve, the government will choose shortage or join with the enterprises. When the shortage cost is less than the cost of enterprise reserve, the government will choose shortage.
