交通基础设施与中国区域经济一体化

利用2008年中国交通部省际货物运输周转量的普查数据,本文在引力方程的基础之上引入交通变量,以此来验证交通基础设施对中国区域经济一体化的影响。实证结果表明:(1)2008年中国省际贸易的边界效应处于6—21之间,这一数值与发达国家之间贸易的边界效应值比较接近;(2)交通基础设施的改善对中国的区域贸易产生了显著的正向影响;(3)交通基础设施越发达,则边界效应越低,说明交通基础设施促进中国区域贸易量的增加主要是促进了省际之间的贸易增加。所有这些均表明交通基础设施的改善对区域经济一体化的促进作用。

Transportation Infrastructure and Regional Economic Integration In China

Using the census data of inter-provincial transport freight turn-over collected by Chinese Transport Ministry in 2008,this paper introduces transport variable based on gravity equation and uses the equation to test on the impact on regional economic integration of transport infrastructure. The empirical results indicate: (1) The border effect of China’s inter-provincial trade in 2008 is between 6—21,which is similar to that of the trade between developed countries; (2)The improvement of transport infrastructure has generated positive impact on China ’s regional trade; ( 3 ) As transport infrastructure becomes more developed,the border effect of trade is decreased,which means that transport infrastructure contribute to promote regional trade mainly through inter-provincial trade. All of that indicates the positive impacts on regional integration of the improvement of transport infrastructure.
