摘　　要：农业生产集聚及技术支撑主体嵌入能够激发社会网络的学习效应,促进新技术信息知识的传播与扩散,从而对农户采纳新技术行为产生空间影响。以行政村层面淡水养殖微生物调水技术采纳行为为研究对象,利用村-户对接的调研数据,采用空间Durbin模型实证检验了养殖集聚及技术支撑主体嵌入对技术采纳的空间影响,主要结论有:(1)农户采纳技术行为和掌握技术水平在行政村层面表现出明显的空间特征,行政村层面农户技术投入强度和掌握技术水平的差异显著,且在相邻村庄之间存在显著正的相关性;(2)养殖集聚能够促使技术信息知识在村内传播,从而显著促进村内技术使用强度的提升,但对邻近村庄农户采纳技术行为没有产生显著的溢出效应;(3)公共技术支撑主体嵌入养殖集聚能够促使技术信息知识在村内传播,从而显著正向影响村内农户采纳技术强度,但对邻近村庄农户采纳技术行为没有产生显著的溢出效应;(4)盈利性技术支撑主体嵌入养殖集聚不仅促使技术信息知识在村内传播,还能促使技术信息知识扩散到邻近村庄,从而对农户采纳技术行为产生显著的空间直接效应和溢出效应。Through theoretical deduction,his paper argued that cultivation agglomeration and technology supporter can stimulate the study effect of social network and promote the dissemination of new technique information,resulting in the spatial effect on the adoption of new agricultural technology on the part of farming households.Taking microbial water transfer technology in the level of village as a research object,and using spatial Durbin Model to test spatial effect caused by cultivation agglomeration and technology supporter based on the survey data of households docked to village,the main research conclusions are:The technology input and mastering level of villagers show a significant difference and have a significantly positive correlation in adjacent villages;cultivation agglomeration can only promote the spread of new knowledge in this village and produce significant positive effect on the adoption of new agricultural technology in this village;public technology supporter embedded in the cultivation agglomeration can only promote the spread of new knowledge and produce significant positive effect on the adoption of new agricultural technology in this village;profit technology supporter embedded in the cultivation agglomeration can promote the spread of new knowledge in this and adjacent villages and enable information to produce significant spatial direct and indirect effect on the adoption of new agricultural technology
