交通发展对区域经济差距的影响

Influences of traffic development on regional economic disparities

基于空间杜宾模型考察了交通发展对区域经济差距的影响及其差异性。结果显示:整体来看,交通发展缩小了我国区域间的经济差距,促进了区域间的经济平衡;交通基础设施的发展及客运周转量的增加会扩大区域间的经济差距,具有极化效应;货运周转量的增长会缩小区域间的经济差距;交通发展对区域间经济差距的影响具有显著的空间溢出效应,其中间接效应大于直接效应,溢出影响的空间辐射半径约为1000公里;交通基础设施对区域经济差距的极化效应普遍显著,客运周转量对东中部地区的经济发展差距具有极化效应,对西部地区具有扩散效应;货运周转量有利于东部地区经济差距的缩小,但会扩大中西部区域间的经济发展差距。

Based on Spatial Durbin Model,this essay examines the influence of traffic development on regional economic disparity and its differences.The results show that:Overall,the development of transportation has narrowed the gap of regional economy and promoted the economic balance among regions;The development of transportation infrastructure and the increase of passenger turnover will widen the regional economic gap and have polarization effect;The growth of freight turnover will narrow the regional economic disparity and have diffusion effect;Transportation development has a significant spatial spillover effect on regional economic disparity,in which the indirect effect is greater than the direct effect,with the radiation radius of the spillover effect about 1000 km;The polarization influence of transportation infrastructure on regional economic disparity is generally significant,and passenger turnover has polarization influence on the economic development gap in the central and eastern regions and diffusion effect on the western regions;Freight turnover is conducive to narrowing the economic gap in the eastern region,but it will widen the economic gap between the central and western regions.
