【摘要】：针对目前关于高铁对不同城市影响差异的研究较为缺乏的状况,以长三角通高铁城市为研究对象,采用引力模型,比较2005年和2011年有无高铁两种情形下,城市经济联系度的变化格局。研究结果显示:通高铁后,所有城市的经济联系度均有明显提升,轴线联系更加明显,城市间联系网络化趋势增强,但区域经济联系格局差异加大,传统中心城市的极化作用更强。从集聚与扩散的角度来看,大城市的集聚能力更强,上海、南京、杭州和宁波成为区域经济联系度核心城市;同等级城市之间集聚和扩散更加平衡;在经济发展较好的大城市周边的小城市受到大城市扩散效应的影响而加快发展,但在经济相对落后的地区,高铁反而加速小城市发展要素的流出而进一步被"边缘化"。
[Abstract]:In view of the lack of research on the influence of high-speed rail on different cities, this paper takes the high-speed rail city of Changjiaitong as the research object, and uses the gravity model to compare the change pattern of urban economic connection degree between 2005 and 2011 with or without high-speed rail. The results show that after the high-speed rail connection, the economic connection degree of all cities is obviously improved, the axis connection is more obvious, the networking trend between cities is enhanced, but the difference of regional economic connection pattern is increased, and the polarization effect of traditional central cities is stronger. From the point of view of agglomeration and diffusion, the agglomeration ability of large cities is stronger, Shanghai, Nanjing, Hangzhou and Ningbo become the core cities of regional economic connection, and the agglomeration and diffusion between cities of the same grade are more balanced. In the small cities around the big cities with good economic development, the development is accelerated by the influence of the diffusion effect of the big cities, but in the areas where the economy is relatively backward, the high-speed rail accelerates the outflow of the development elements of the small cities and is further "marginalized".
