摘　　要：近年来,鄱阳湖流域的农业面源污染呈加剧趋势,研究鄱阳湖流域种粮大户对环境友好型技术选择的关联效应与决策机制,对于促进农业绿色发展行动、实施乡村振兴战略具有重要意义。以测土配方施肥和秸秆还田技术为例,构建联立双变量Probit模型,对鄱阳湖流域333个种粮大户样本进行了实证分析。研究结果表明:种粮大户对测土配方施肥和秸秆还田技术两种环境友好型技术之间的选择存在显著的互补效应;相比个人特征和家庭特征变量,社会资本变量和技术信息变量对种粮大户采用环境友好型技术的影响更显著,其中拥有非农就业经历和村干部身份的种粮大户对环境友好型技术的概率会增加;容易获取农技员的技术指导服务,或者从电视、网络等渠道获取农业技术信息均对种粮大户采用环境友好型技术具有促进作用;土地经营面积对种粮大户选择测土配方施肥技术具有显著影响,但影响并非单调一致的,而是呈现显著的倒“U”型关系。为此,提出在环境友好型技术推广过程中需要考虑技术选择之间的互补性以及土地规模边界问题,同时注重利用农户间的社会关系网络,调动种粮大户在环境友好型技术推广中的示范作用,提高环境友好型技术推广政策的精准性和效率。In recent years,agricultural non-point source pollution in Poyang Lake Basin has been aggravating.Studying the correlation effects and decision-making mechanisms of large scale grain producers’ adoption of environmental-friendly technologies is of great significance to the promotion of green agricultural development and the implementation of rural revitalization strategy.Taking formula fertilization and straw returning technology for example,aBivariateProbit model is used to empirically analyze the data of 333 large scale grain producers in Poyang Lake Basin in Jiangxi province.Results show thatlarge scale grain producers’ adoption decisions of environmental-friendly technologies are interrelated.There aresignificant complementary relationships between formula fertilization and straw returning technology.Compared with personal characteristics and family characteristics variables,social capital variables and technological information variables have more significant impacts on large scale grain producers’ adoption of environmental-friendly technologies.Among which,large scale grain producers with non-agricultural employment experience and village cadre status are more likely to select environmental-friendly technologies.Technical guidance services from agricultural technicians,or acquiring agricultural technical information from TV,Internet,and other channels,have positive effects on large scale grain producers’ adoption of environmental-friendly technologies.Operated farm size has a significant impact on large scale grain producers’ adoption of cultivated land protection technologies,and the impact is not monotonous.Operated farm size shows a significant inverted “U” relationship with formula fertilization technology.It is proposed that the complementarity of environmental-friendly technologies and the issue of farm size boundaries need to be considered in the process of extending environmental-friendly technologies.At the same time,it should focus on utilizing the social network among farmers and mo
