摘　　要：应急物资预先采购储备时常面临储量不足或剩余物资过期等问题。对此,根据物资减值规律划分应急物资种类,针对价值稳定但受保质期影响的一类物资,在数量柔性契约基础上考虑储备周期的影响,建立政府主导的应急物资采购模型;通过推导,获得政企合作的条件及双方最优决策,并验证模型相比政府单独储备时的优势,以及模型对不同类型物资的适用性;同时分析若干因素对政企决策及成本收益的影响,并提出相应管理策略。研究显示,该模型能够在控制政府成本保障企业收益的同时,有效提高应急物资储备水平,减少因物资储存而发生的资源浪费。Considering the problem that the reserve materials are insufficient or the remaining materials expired when emergency supplies are pre-purchased for reserve,this study divides the types of emergency materials according to the law of inventory impairment.Focusing on the type of materials with stable value but affected by the shelf life,this study considers the impact of the reserve cycle on the basis of the quantity flexible contract,then establishes a government-led emergency material procurement model.Through the model derivation,the conditions for government-enterprise cooperation and the optimal decision of both parties are obtained,the advantages of the model over the government’s separate reserve model as well as the applicability of the model to different types of materials are verified.This study further analyzes the impact of several factors on the decision-making and cost-benefit of government and enterprises,and proposes the corresponding management strategies.The results show that the proposed model can effectively increase the reserves of emergency supplies and reduce the waste of resources caused by the storage of materials while controlling government costs and ensuring the revenue of the supplier.
