摘　　要：设计了一个基于能力期权契约的应急物资采购模型,政府作为唯一的采购方期初向一个合约供应商采购实物储备量,并向供应商购买一定量的生产能力期权,一旦在期权执行期内有应急物资需求发生,可立即将供应商储备的生产能力转化为实物产品.通过推导和算例模拟证明,这样的采购机制任大量减少政府应急物资实物储备量的同时,降低了政府的缺货风险.同时,也合理补偿了灾后供应商被安排突击生产应急物资发生的成本,应急物资供应链实现了协调,供和需双方实现了双赢.This paper designs an emergency supplies purchasing model based on capac- ity option contract in which the government is the only one purchaser with only one supplier. Initially, the government purchases a certain amount of real emergency supplies as real reserves and a certain amount of production capacity which could be immediately into real emergency supplies once emergency supplies demand occurs. After derivation and example simulation, we find such procurement mechanism could reduce government＇s real reserves a lot while govern- men＇s shortage risk of emergency supplies could be reduced. The procurement mechanism also compensates the supplier＇s cost caused by assault production after disaster reasonably. The supply chain realizes coordination and both the government and the supplier realize a win-win situation.

关 键 词：应急物资 实物储备 能力期权契约 供应链协调.
