The multi-stage joint reserve mode of emergency supplies can effectively expand the reserve amount of emergency supplies and reduce the risk of reserve shortage faced by both the government and enterprises.The uncertainty of emergencies brings challenges to the government's reserve of emergency supplies.In order to ensure that the demand for emergency supplies is guaranteed to the greatest extent after emergencies occur,the government-enterprise agreement reserve led by the government should be initiated to improve the reserve capacity of emergency supplies.Considering the situation of post-disaster emergency supplies shortage caused by raw materials supply shortage,this paper constructs the multi-contract decision model in which the government initiates commodity option agreement with manufacturers,who sign raw material storage contract with suppliers based on subsidies.Further,it explores the ways in which disaster probability,shortage cost,royalty,manufacturers and suppliers of prices subsidies affect enterprise reserve decision.This paper discusses the significance and application scope of the three-level reserve by adding suppliers on the basis of the two-level government-enterprise agreement reserve.
