互联网农业信息获取与农户农机社会化服务采纳

针对农村互联网使用能否有效推动农户农业机械化发展这一现实问题，基于微观数据，采用OLS模型估计农户通过互联网获取农业信息对农机社会化服务采纳的影响，并使用工具变量法和处理效应模型控制内生性，同时进行多种稳健性检验和异质性分析。结果表明：1)通过互联网获取农业信息与农户农机社会化服务采纳为负相关关系，使用2种不同方法控制内生性得出的系数分别为-2.3和-1.8;2)异质性检验显示，互联网信息获取与农机社会化服务采纳的反向关系在老年农户和经营规模极小农户的样本中并不成立；3)机制检验显示，互联网信息获取对农户自购农机有显著的促进作用。使用互联网获取农业信息在现阶段抑制了农户农机社会化服务采纳，但有助于推动农户自购农机；在通过互联网获取信息到有效利用网络信息获取收益之间还有更深层次的数字鸿沟。

Agricultural information access from internet and farmers' adoption of socialized service of agricultural machinery

To solve the problem of whether the use of rural internet can effectively promote the development of agricultural mechanization, based on the micro data, an OLS model is used to estimate the impact of farmers'' access to agricultural information through the internet on their adoption of the socialized service of agricultural machinery. The instrumental variable method and the treatment effect model are used to control the endogenous. A variety of robustness tests and heterogeneity analysis are carried out. The results show that: 1)The relationship between access to agricultural information through the internet and the adoption of socialized service of agricultural machinery by farmers is negative. The coefficients obtained by using two different methods to control endogenous are -2. 3 and -1. 8, respectively; 2)Heterogeneity test shows that the coefficients between internet information access and agricultural machinery service outsourcing adoption are not significant in the sample of elderly farmers and small-scale farmers; 3)The mechanism test shows that internet information acquisition has a significant promotion effect on farmers'' self-purchase of agricultural machinery. Internet information acquisition inhibits farmers'' adoption of the socialized service of agricultural machineryg, but promotes farmers purchase agricultural machinery by themselves. There is a deeper digital gap between obtaining information through the internet and benefit from internet information.
