【摘要】：本文将信息要素纳入生产模型中分析了信息对农户采纳新技术的影响,并从强、弱关系的视角理论分析了农户社会网络对获取技术信息的影响机制,以淡水养殖户微生物调水技术采纳为例,建立计量模型检验理论假说,研究发现:掌握新技术信息显著正向影响农户采纳技术;在中国农村的社会背景下,格兰诺维特"弱关系假设"不能完全解释农业新技术信息传递机制,表现在:强关系对农户获取技术信息有显著正向影响,弱关系对农户获取新技术信息没有直接促进作用,其发挥作用需要借助由强关系充当的关系桥;弱关系在信息流动中的作用不一定大于强关系,在横向和纵向网络中,强关系对农户掌握新技术信息的直接促进作用更为凸显,而在斜向网络中,弱关系通过关系桥对农户掌握新技术信息的间接促进作用更为凸显。
[Abstract]:This paper analyzes the influence of information on the adoption of new technologies by farmers by integrating information elements into the production model, and analyzes the influence mechanism of farmers' social networks on obtaining technical information from the perspective of strong and weak relationship. Taking the adoption of microbial water transfer technology by freshwater breeders as an example, an econometric model was established to test the hypothesis. It was found that mastering new technology information significantly positively affected farmers' adoption technology; in the social background of China's rural areas, Granovit's "weak relationship hypothesis" can not fully explain the mechanism of agricultural new technology information transmission, which shows that strong relationship has a significant positive effect on farmers' access to technical information, and weak relationship has no direct promoting effect on farmers' access to new technology information. The role of weak relationship in information flow is not necessarily greater than that of strong relationship. In horizontal and vertical networks, the direct promotion of strong relationship to farmers' mastering new technology information is more prominent. In oblique network, weak relationship plays an important role in promoting farmers to master new technology information through relationship bridge.
