农村交通基础设施投资对农民收入影响的区域比较——基于中国30个省区1999—2008年的面板数据分析

Regional comparison of rural transportation infrastructure investment and farmers' income:Based on the panal data within 30 provinces in China from 1999 to 2008

以柯布-道格拉斯生产函数为基础,选用中国30个省市自治区1999-2008年的面板数据,建立多对数函数计量经济分析模型,并选取个体固定效应模型实证分析农村交通基础设施投资对农民收入的影响.研究结果表明:中国农村交通基础设施投资对农民收入的贡献率在0.02～0.09之间,有着明显的正向促进作用,但这种带动性还没有充分体现出来;农村交通基础设施投资对农民收入的贡献率在区域之间存在差异,东、西部地区比较显著,中部地区不是很显著.据此,提出各个地区应充分利用政策契机,发挥农村交通基础设施投资所带来的优势交通条件,促进农村剩余劳动力向非农业生产劳动的转移,增加农民收入.

Based on Cobb-Douglas production function,selected panel data within 30 provinces from 1999 to 2008, established econometrics model of Multi-Logarithmic function,this paper empirically analyzes the effect of rural transportation infrastructure on farmers'income by choosing individual fixed effect model.Empirical study shows that: Chinese rural transportation infrastructure plays a positive role in farmers'income(the impacts rate of transportation infrastructure on farmers'income is 0.02-0.09),but this role differs remarkablly in the eastern and western regions,while the central region is not significant.This paper,finally,points out that each area should take advantage of beneficial transportation conditions and policy chances,which is brought by the investment of rural transportation infrastructure, promote the transfer of rural surplus labor to non-agricultural industries,and increase farmers'income.
