农用地流转与农户收入的关系分析——以农业机械化水平为视角

Circulation of agricultural land and household income:Taking the level of agricultural mechanization as a perspective

通过对2005—2019年不同省份农用地流转率、农业综合机械化水平以及农民家庭人均可支配收入等数据的分析,从宏观层面考察了农用地流转、农业机械化水平与农户收入三者间的关系,并检验了其中的中介效应机制。同时还将全国各地划分为东部、西部、中部3个区域进行了分样本回归。结果表明,从总体来看,加快农用地流转不仅能显著促进农民收入的增加,还能提高农业机械化水平;农业机械化水平的提高不仅可以直接促进农民收入的增加,而且可以作为农用地流转与农民收入之间的中介变量,间接增加农民收入。从分样本来看,东部、西部、中部不同地区农用地流转都可以促进农民收入的提高。农业机械化水平均与农民收入呈正相关,农业机械化水平的部分中介效应也几乎都成立。但西部地区农用地流转对农户的增收效应以及农业机械化对农户收入的促进效应明显高于其他两个地区。

Through the analysis of the data of agricultural land transfer rate,comprehensive agricultural mechanization level and per capita disposable income of farmers’families in different provinces from 2005 to 2019,the relationship between circulation of agricul⁃tural land,agricultural mechanization level and farmers’income was examined from the macro level,and the intermediary effect mechanism was tested.At the same time,the whole country was divided into three regions:East,west and central for sub-sample re⁃gression.The results showed that from a general point of view,accelerating the circulation of agricultural land could not only signifi⁃cantly promote the increase of farmers’income,but also improve the level of agricultural mechanization;the improvement of the level of agricultural mechanization could not only directly promote the increase of peasant income,but also as an intermediary variable be⁃tween circulation of agricultural land and peasant income,bring about an indirect increase in peasant income.From the perspective of sub-samples,the circulation of agricultural land in different regions of the east,west and central regions all could promote the im⁃provement of farmers’income.The level of agricultural mechanization was positively correlated with farmers’income,and the partial mediating effect of agricultural mechanization level was almost valid.However,the effects of circulation of agricultural land on farmers’income and the promotion effect of agricultural mechanization on farmers’income in the western region were significantly higher than those in the other two regions.
