摘　　要：城市群交通网络一体化是否在促进经济增长的同时引发经济活动在城市间的重新分布效应,是一个值得关注的问题。本文在定量测度中国10大城市群交通网络一体化水平的基础上,实证检验了城市群交通网络一体化水平对城市自身经济增长的影响。研究发现,城市群交通网络一体化水平对城市经济增长有显著的正影响,从而支持了交通基础设施改善对区域经济增长具有扩散效应的理论预期。进一步的影响机制检验表明,城市群交通网络一体化通过促进城市群商品市场一体化和劳动力市场一体化的途径,最终促进了城市经济增长,即城市群交通网络一体化水平和城市经济增长的中介效应存在。因此,城市群交通网络一体化水平的提升,有利于促进商品和生产要素在城市群内部更加充分和自由的流动,从而促进城市群经济协调增长。Whether the integration of transportation network in urban agglomerations triggers a redistribution effect of economic activities among cities while promoting economic growth is a matter of concern.Based on the quantitative measurement of the level of transportation network integration in China’s 10 largest urban agglomerations,this paper empirically tests the influence of the integration level of urban transportation network on urban economic growth.It is found that the integration level of urban transportation network has a significant positive impact on urban economic growth,thus supporting the theoretical expectation that transportation infrastructure improvements have a diffusion effect on regional economic growth.Further influence mechanism test shows that the integration of transportation network in urban agglomeration ultimately promotes urban economic growth through the pathway of promoting the integration of commodity markets and labor markets in urban agglomerations,i.e.,a mediating effect exists between the level of integration of transportation network in urban agglomerations and urban economic growth.Therefore,the improvement of the integration level of transportation network in urban agglomerations is conducive to the more full and free flow of commodities and production factors within urban agglomerations,thus promoting the coordinated economic growth of urban agglomerations.
