摘　　要： 为了响应国家脱贫攻坚的号召,越来越多的公司(如龙头农业企业)开始通过订单农业的方式参与扶贫.综合考虑我国扶贫政策,引入土地规模约束、扶贫产品偏好等特征,建立了由农户和公司组成的订单农业供应链模型,其中农户和公司进行一个以公司为主导者的Stackelberg博弈.据此对比分析不同的政府补贴方式下农户生产决策、企业扶贫行为以及社会福利.研究表明,扶贫成本的降低、扶贫效果系数和消费者扶贫产品偏好增加会促使农户扩大生产量/种植面积、公司提高扶贫水平,进而提升整个供应链绩效水平以及社会福利,减小政府补贴压力.而政府补贴金额因受到土地规模约束,并不是越高越好,当土地规模比较小时,政府最优决策是不补贴;当土地规模中等时,政府可以补贴公司或者农户;当土地规模比较大时,若政府基于社会福利最大化进行决策,应该补贴公司,而若政府基于考虑扶贫补贴效率进行决策最大化,应该补贴农户. In response to the country’s call for poverty alleviation,more and more companies(e.g.,leading agricultural enterprises) have begun to participate in poverty alleviation through contract farming.With the consideration of China ’s poverty alleviation policies,and introducing the characteristics of land size constraints and product preference for poverty alleviation,this paper establishes an contract-farming supply chain model consisting of a farmer and an agribusiness company,in which the farmer and the company play a Stackelberg game with the company as the leader.Then we analyze the production decision of the farmer,the poverty alleviation behavior of the company,and social welfare under different government subsidy policies.The result shows that decreasing the poverty alleviation cost,or increasing the poverty alleviation effect coefficient and the consumer poverty alleviation preference will encourage the farmer to expand the production quantity/planting areas and the company to increase the optimal poverty alleviation level,thereby improving the performance of the entire supply chain and social welfare,and reducing the pressure of government subsidies.We find that the amount of government subsidies is restricted by the scale of land.Specifically,when the land scale level is relatively small,it is better for the government not to subsidize;when the land scale level is medium,the government can subsidize the company or the farmer;and when the land scale level is relatively large,the government should subsidize the company based on maximizing social welfare,and subsidize the farmer based on maximizing the efficiency of poverty alleviation subsidies.
