公路交通基础设施与收入差距的理论与实证分析

基于公路交通基础设施对经济增长和生产效率持正向作用这一共识，利用中国29个省市的动态面板数据模型验证公路交通基础设施对中国收入差距的影响。分析认为：公路交通基础设施建设水平可以缩小城镇居民收入差距与总体居民家庭人均收入差距；对于农村居民家庭人均收入而言，公路交通基础设施水平只有在达到一定阈值之后才会降低其收入差异。

Theoretical and empirical analysis on highway transportation infrastructure and income gap in China

This paper has analyzed the action mechanism of highway transportation infrastructure and resident income gap and concluded that it has different affecting directions to the regional income gap. The paper then verifies the influence of the highway transportation infrastructure on income gap with the 29 Chinese provincial panel data. The result shows that the gap transportation infrastructure can dramatically reduce the variation of regional income gap for per capita income of urban households. However, when per capita income of rural households is concerned, the gap transportation infrastructure will do the same thing only after reaching a certain threshold.
