摘要:

改善基础设施和居住环境是实现全面脱贫的前提条件之一,通过基础设施投入促进要素流动,从而缩小居民收入差距问题也已成为脱贫攻坚的重要着力点。交通基础设施因投入金额高,其带来的收入分配效应也受到越来越多关注,但鲜有研究深入地分析农村公路对农民间收入差距的影响。本文基于1993-2013年间中国30个省市区的面板数据,运用固定效应计量模型检验了农村公路对农民收入差距的影响。结果表明:中国农村公路对省际间农民收入差距具有的“正U型”影响作用;国省干线公路有助于缩小省际间农民收入差距;受教育水平、农业固定资产投入、城镇化水平以及地区经济发展水平对省际间农民收入差距同时存在多重影响效应。最后在实证检验的基础上,本研究从理论角度分析了农村公路影响农民收入差距的作用机理,并重点分析了农村公路供给与农民收入差距间“正U型”关系的产生原因的迁徙。


Abstract:

To achieve complete poverty alleviation, the improvement of infrastructure and living conditions is fundamental.  Promoting  the flow of factors through infrastructure investment, thereby reducing the income gap among residents, has become an important focus of poverty alleviation.  Because of the high amount of investment in transportation infrastructure, greater attention has been paid to the income distribution effect it brings, but few studies have analysed the effect of rural highways on the income gap of farmers.  Based on the panel data pertaining to 30 provinces in China from 1993 to 2013,  this paper uses a fixed-effect model to test the impact of rural highways supply on the income gap of farmers.  The empirical results show that: (1) The effect of Chinese rural highways on the farmers’ income gap among provinces is “U-shaped”.  (2) Chinese national and provincial trunk highways are helpful in narrowing the farmers’ income gap among provinces.  (3)  The level of education, household productive fixed assets investment, level of urbanization, and level of regional economic  development have multiple effects on the farmers’ income gap among provinces.  Then, based on the empirical analysis, the paper analyzes the mechanism of rural highways affecting the income gap of farmers from a theoretical perspective and focuses on the causes of the “U-shaped” relationship between rural highways supply and farmers’ income gap.
