摘要：为促进区域一体化协同发展，根据南京-合肥双都市圈的铁路客运车次、类型和方向，测算铁路客运的吸附指数和依附指数，表征城市间的联动结构、联动强度与联动方向。研究表明：城市自身的经济发展水平和人口净流入与中心城市对个体城市的吸附能力正相关，表现为强强联动的合作趋势；个体城市吸附能力对腹地城市与中心城市联动程度的影响为显著正向关系，推动双都市圈内各城市间出现竞争态势；受2个都市圈的空间邻近效应和空间叠加效应影响，滁州、马鞍山、芜湖等城市的发展潜力较大。实现城市高质量发展，要正确把握经济发展的规律，城市间强强联合；掌握区域内发展差异的适宜度，推进构建交通一体化体系，共建畅达都市圈。

Abstract: In order to promote the coordinated development of regional integration, the adsorption index and dependency index of railway passenger transport are calculated according to the number, type and direction of railway passenger transport in the Nanjing-Hefei metropolitan area, representing the linkage structure, linkage strength and linkage direction among cities. The research shows that: The city′s own economic development level and net population inflow are positively correlated with the central city′s adsorption capacity to individual cities, which shows a strong and strong linkage cooperation trend; The influence of individual city adsorption capacity on the linkage degree of hinterland cities and central cities is a significant positive relationship, which promotes the competition among cities in the dual metropolitan area; Affected by the spatial proximity effect and spatial superposition effect of the two metropolitan areas, Chuzhou, Maanshan, Wuhu and other cities have greater development potential. In order to realize the high-quality development of cities through the combination of powerful cities, the law of economic development should be correctly grasped; Master the suitability of regional development differences, promote the construction of integrated transportation system, and build a smooth metropolitan area.
