中文摘要：

研究证实社会网络是农户技术采用的重要影响因素,对农户技术采用的影响机制复杂,那么社会网络是通过哪些路径影响农户技术采用的呢？基于此,本文以甘肃民勤节水灌溉技术采用为例,采用农户调查数据,利用KHB模型分解社会网络对农户技术采用的直接效应和间接效应。结果发现：社会网络通过直接影响和间接影响两种路径对农户技术采用行为产生影响,其中直接影响处于主导地位;社会网络对农户技术采用行为的间接影响可通过五条路径实现,其中收入结构与收入水平反向影响农户技术采用,信贷约束、种植结构和技术认知正向影响农户技术采用,并且信贷约束影响作用最大。

英文摘要：

The influence mechanism of how social networks effect farmer households＇ technology adoption is complicated. And the influence paths should be further studied. Based on the household survey data of water- saving irrigation technology adoption of Minqin County,Gansu Province,this paper decomposes the influence path of social networks affecting farmer households＇ technology adoption. The results show the following：1） social networks effect farmer households＇ technology adoption through two ways： direct effects and indirect effects,and the direct effects occupy a dominant position. 2） the indirect effects of social networks influence technology adoption through five mediate variables： income structure,income level,credit constraints,planting structure and technology cognition.
