货物运输对城市经济发展的空间计量研究——基于四大区域差异化的视角

The Study on the Impact of Freight Transportation on Urban Economic Development——From the Perspective of Traffic Mode Differentiation

交通是城市经济发展的生命线,国内外学者对交通运输于城市经济发展的影响缺乏深入研究。从区域差异化的视角入手,分别考察总货运交通,细分为公路、铁路、水路三种货运交通运输方式对城市经济发展的影响,通过建立固定效应计量模型和空间杜宾模型,得出结论为:货运交通能给城市经济发展带来显著性影响;不同的货运交通运输方式,对城市经济发展的影响效应存在显著差异;各地区的货运交通运输方式差异明显,对城市经济发展的影响程度不一致;同时全国及四大区域的货运交通对城市经济均存在明显的空间溢出作用,且空间溢出作用随空间距离的增加而减弱。并通过了空间GMM模型和改变时间区间的稳健性检验。并针对当前的货运交通发展现状,提出相应的政策性建议。

Transportation is the lifeline of urban economic development.Many scholars have studied the factors that affect the urban economic development,and regard transportation as the control variable.There is no in-depth study on the impact of transportation on urban economic development.From the perspective of traffic mode differentiation,this paper examines the impact of freight transportation on urban economic development,and through the establishment of fixed effect model and spatial durbin model to analyze,draws the following conclusions:freight transportation can bring significant impact on urban economic development;different modes of freight transportation have different effects on urban economic development;the difference of freight transport modes between districts is obvious,and the degree of influence on urban economic development is not consistent,at the same time,special overflow effect weakens as increasing special distance,and the empirical result passes the robustness test of special GMM model and change of time range.On the basis,the policy recommendations are put forward for the current traffic development status.
