农村一二三产业融合发展对农民收入的影响及其区域异质性分析

The Impact of Integrated Development of the Primary,Secondary and Tertiary Industries in Rural Areas on Farmers’Income and Its Regional Heterogeneity

利用2008-2016年中国省级面板数据,在综合测算农村一二三产业融合发展指数的基础上,运用系统广义矩估计和固定效应模型,实证考察农村一二三产业融合发展对农民收入的影响及其区域异质性。研究发现,农村一二三产业融合发展对中国各地区农民收入均具有显著的提升作用;进一步引入虚拟变量探究区域差异的研究结果表明,农村产业融合发展水平较高的地区对农民收入的提升效应也较强,其收入效应在东部、中部、西部三大区域呈现递减趋势。各地区要继续推动农村一二三产业融合发展,构建农村一二三产业融合发展体系,重视农村一二三产业融合发展收入效应的区域差异,使农村一二三产业融合发展的收入效应实现最大化。

Using the provincial panel data in China from 2008 to 2016,based on a comprehensive measurement of the integrated development of the primary,secondary and tertiary industries in rural areas,this paper adopts the system Generalized Method of Moments and fixed effects model,and then empirically studies the impact of the integrated development of rural industries on farmers’income and its regional heterogeneity.The study found that the integrated development of the primary,secondary and tertiary industries in rural areas has a definite effect on increasing farmers’income in various regions of China.The results of further introduces dummy variables to explore regional differences shows that regions with higher levels of integrated development of rural industries have stronger effect on increasing farmers’income.Its income effect shows a decreasing trend in the three regions of east,middle and west.All regions should continue to promote the integrated development of the primary,secondary and tertiary industries in rural areas,construct the integrated development system of the primary,secondary and tertiary industries in rural areas,pay attention to regional differences in the income effect of integrated development of rural industries,to maximize the income effect of integrated development of rural industries as much as possible.
