摘要:

以甘肃省民勤县农户调研数据为基础,构建结构方程模型,实证分析了社会网络、推广服务两种渠道对农户节水灌溉技术采用的影响。结果表明:①民勤地区农户节水灌溉技术采用积极性普遍不高,采用意愿较弱,采用面积较小,尤其是节水灌溉支付意愿处于较低水平;②社会网络、推广服务对农户节水灌溉技术采用均具有显著正向影响;③社会网络对节水灌溉技术采用的影响作用存在直接效应和间接效应,直接效应表现为社会网络内在维度对节水灌溉技术采用的促进作用,间接效应表现为社会网络可以正向影响推广服务效果,进而促进技术采用;④水资源稀缺认知和技术的有用性认知可以促进技术采用,良好的社区环境可为技术采用提供外在保障。最后根据实证结果提出相应的政策建议。

Abstract:

From the simultaneous perspective of social network and extension services,we aimed to explore these two information channels in the water-saving technology adoption behavior of farmers. Based on survey data from Minqin County,Gansu,China we established structural equation models to analyze how social networks and extension services affect farmers’ water-saving irrigation technology adoption. We found that farmers enthusiasm for water-saving irrigation adoption is generally low; most farmers adopt water-saving technology with weak willingness and across small areas. There is an especially low level of willingness to pay. Social networks and extension services both have positive significant impacts on farmers water-saving technology adoption,indicating they play crucial roles in facilitating technology adoption. Social networks have both direct and indirect effects on water-saving irrigation technology adoption:internal dimensions of social networks have direct effects on promoting farmers water-saving irrigation technology adoption;and social networks also positively affect effectiveness of extension services,thus indirectly contributing to technology adoption. Farmers awareness of water scarcity and cognition of technology usefulness can facilitate technology adoption,and a good community environment can guarantee technology adoption. Appropriate policy recommendations are proposed based on our empirical results,such as providing funding and policy support for adopters,improving the promotional effects of model households,carrying out trading activities for farmers and providing good social environments.
