摘　　要：在各级政府鼓励企业参与区域农户脱贫致富的背景下,本文针对生鲜农产品的供应链网络,同时考虑了生产外包和物流外包,通过引入平均新鲜度来刻画需求市场对生鲜农产品新鲜度的要求,以生鲜企业利润最大化为目标,构建了含有平均新鲜度约束的广义纳什均衡模型。然后,利用Karush-Kuhn-Tucker条件和互补函数,将广义纳什均衡模型转化为非线性方程组来求解。进一步,利用GAMS进行了数值仿真实验,并对政府补贴率、平均新鲜度和生产外包网络结构给出了灵敏度分析。初步的数值结果表明,增加政府补贴率,有利于促进生鲜企业参与区域农户脱贫,提高生鲜企业利润;当平均新鲜度下限超过某一阈值时,生鲜企业倾向于内部生产和内部运输;引入生产外包,有利于增加市场供给,降低市场价格,提高生鲜企业利润,进而实现各方共赢。Under the background that governments encourages enterprises to participate in regional farmers'poverty alleviation,this paper takes both production and logistics outsourcings into account in a supply chain network of fresh agricultural products,and by introducing the average freshness to describe the demand of fresh agricultural products in demand markets,establishes ageneralized Nash equilibrium model with average freshness constraint by maximizing the profits of fresh enterprises.Then,by means of the Karush-Kuhn-Tucker conditions and some complementarity function,the generalized Nash equilibrium model is transformed into nonlinear equations.Furthermore some numerical experiments are carried out by using gams and sensitivity analysis for government subsidy rate,average freshness and network structure of production outsourcing is also given.Preliminary numerical results reveal that increasing the government subsidy rate is helpful to promote fresh enterprises to participate in regional farmers'poverty alleviation,which may also improvefresh enterprises'profit;when the lower limit of average freshness exceeds a threshold,fresh enterprises prefer internal production and transportation;the production outsourcing is helpful in increasing market supplies,reducing market prices,and boosting fresh enterprises'profit so as to achieve a win-win situation for all parties.
