摘　　要：在不同土地细碎化条件下,厘清影响稻农生物农药施用行为的关键因素,对实现农药减量、保障农产品质量安全具有重要现实意义。基于2017年湖北省765份农户实地调研问卷,从追求风险最小化、利润最大化以及食品安全3个方面构建稻农生物农药施用行为多目标效用模型,实证检验不同土地细碎化条件下种粮目的对稻农生物农药施用行为的异质性影响。结果显示:①以自留口粮占比表征的种粮目的,越趋向于满足自家消费需要,稻农施用生物农药的可能性越大,且自留口粮占比每提高1%,施用生物农药的可能性会提高10.56%;②对于土地细碎化程度低(平均地块面积大于0.133 hm^2)的稻农而言,种粮目的对其生物农药施用行为产生负向影响,而对于土地细碎化程度高(平均地块面积小于0.133 hm^2)的稻农而言,种粮目的表现为正向影响;③稻农生物农药施用行为也会受到农药残留意识、绿色农产品重要性认知、市场风险感知以及健康水平的正向影响,以及市场风险感知的负向影响。根据研究结论提出政策建议:加快农田标准化建设,实现同质化生产,同时加快普及新型农业技术和农业发展形势,从生产源头和市场建设双管齐下。Under different conditions of land fragmentation,it is of great practical significance to clarify the key factors that affect the application of biological pesticides by rice farmers to reduce the amount of pesticides and ensure the quality and safety of agricultural products.Based on 765 field survey questionnaires of farming households in Hubei Province in 2017,a multi-objective utility model of rice farmers’bio-pesticide application behavior was constructed from the three aspects of risk minimization,profit maximization,and food safety,to empirically test the heterogeneous influence of grain growing objectives on rice farmers’bio-pesticide application behavior under different land fragmentation conditions.The results show that:first,using the indicator of percentage of grain production for self-consumption,the more likely the products are to meet their own consumption needs,the greater the possibility that farming households would apply biological pesticides.Moreover,the possibility of applying biological pesticides will increase by 10.56%for every 1%increase in the proportion of self-reserved grain ration.Second,for rice farmers with a low degree of land fragmentation(the average plot area is greater than 0.133 hm2),the purpose of grain growing has a negative impact on the application of biological pesticides,while for rice farmers with a high degree of land fragmentation(the average plot area is less than0.133 hm2),the purpose of grain growing shows a positive impact.Third,the application of biological pesticides by rice farmers is also positively affected by the awareness of pesticide residues,the awareness of the importance of green agricultural products,market risk perception and health level,as well as negatively affected by market risk perception.According to the conclusions,we put forward the following policy suggestions:the government should accelerate the construction of farmland standardization to realize homogeneous production,and accelerate the popularization of new agricultural technologies a
