摘要
城市群依托发达的交通基础设施网络,形成紧密的经济联系,促进城市群一体化的发展.文章基于1990年、2000年、2010年、2020年中国14个城市群186个城市的面板数据,构建指标体系来评价中国城市群一体化发展程度.利用Arcgis揭示了中国城市群间的空间异质性和时空演化特征,并且构建空间杜宾模型(SDM),探讨了交通基础设施对城市群一体化及其子系统的影响.研究结果表明:(1)各大城市群一体化水平整体呈现上升趋势,具有明显的空间集聚特征,从1990年到2020年,城市群一体化中存在显著的空间溢出效应,并且这种空间溢出强度随时间逐渐增强;(2)各个城市群内部呈现核心放射状格局,城市群内城市发展差距逐渐减小,低级别城市数量不断减少;(3)影响城市群一体化指数的主要子系统是要素市场和公共服务.交通基础设施对城市群一体化有正向的空间效应;对本地要素市场存在显著的负向空间效应,对周围地区要素市场存在正向的空间溢出效应;对公共服务存在正向的空间效应;对生态环境产生显著的正向空间效应.
Urban agglomerations,relying on well-developed transportation infrastructure networks,form close economic connections that promote the integrated development of urban agglomerations.Based on panel data of 186 cities from 14 urban agglomerations in China for the years 1990,2000,2010,and 2020,this paper constructs an index system to assess the degree of integrated development of urban agglomerations.Arcgis is employed to reveal the spatial heterogeneity and spatiotemporal evolution characteristics among urban agglomerations.Furthermore,SDM is established to investigate the impact of transportation infrastructure on the integration of urban agglomerations and their subsystems.The research findings are as follows.(1)The overall level of integration among major urban agglomerations shows an upward trend and exhibits distinct spatial agglomeration characteristics.Over the period from 1990 to 2020,there is significant spatial spillover effect in the integration of urban agglomerations,and this spillover intensity increases over time.(2)Each urban agglomeration demonstrates a core-radiation pattern internally,and the development gap among cities within each agglomeration gradually diminishes,leading to a reduction in the number of lower-level cities.This might indicate that the internal connections and cooperation among cities within urban agglomerations are strengthening,resulting in urban agglomeration and balanced development.(3)The main subsystems influencing the index of urban cluster integration are factor markets and public services.Transportation infrastructure has a positive spatial effect on the integration of urban agglomerations.It exhibits a significant negative spatial effect on the local factor market,while showing a positive spatial spillover effect on the surrounding factor market.It also has a positive spatial effect on public transportation and significantly positive spatial effect on the ecological environment.
