【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]:Based on the survey data of farmers in Minqin County of Gansu Province, a structural equation model was established, and the effects of social network and extension service on the adoption of water-saving irrigation techniques were analyzed empirically. The results showed that the enthusiasm of water-saving irrigation was not high, the willingness to adopt was weak, the area was small, especially the willingness to pay for water-saving irrigation was at a lower level in Minqin area. Extension service has significant positive and indirect effects on the adoption of water-saving irrigation technology for farmers, which has direct and indirect effects on the adoption of water-saving irrigation technology by social network. The direct effect is the promotion effect of the inherent dimension of social network to the adoption of water-saving irrigation technology, and the indirect effect is that the social network can positively affect the effect of extension service, and then promote the adoption of technology. (4) knowledge of water scarcity and usefulness of technology can promote technology adoption, and good community environment can provide external guarantee for technology adoption. Finally, according to the empirical results, the corresponding policy recommendations are put forward.
