摘要
数字经济背景下,虚拟集聚与地理集聚的互动融合对城市群空间重构产生深刻影响。通过挖掘虚拟集聚与地理集聚的互动融合关系,基于2003—2019年中国10个城市群的多源数据,测算各城市群的双重集聚耦合度、空间多中心指数、空间网络化特征等并开展实证分析。理论分析认为,虚拟集聚与地理集聚的互动融合深刻影响微观主体的区位选择,进而作用于宏观层面的经济活动空间分布,通过强化城市群内部网络联系促进其空间结构的多中心化发展。实证结果表明:城市群双重集聚耦合对推动其空间结构的多中心化发展具有显著的正向影响,并通过提升个体城市节点属性、推动局部城市跨域协作、促进城际交互联系等提升城市群空间结构的网络化特性,加速形成多中心空间分布格局。研究成果为深入理解数字经济时代城市群空间结构优化的驱动机制与实现路径提供借鉴与参考。
In the digital economic era, the interaction and fusion of virtual agglomeration and geographical agglomeration have a huge impact on the spatial structure of urban clusters.The essay establishes a theoretical framework of dual agglomerations influencing urban clusters' spatial structural development, and conducts an empirical analysis based on multiple sources of urban data illustrating 10 urban clusters in China, from 2003 to 2019,including coupling degree, spatial multiple-center index and networked features.The theoretical framework shows that the interaction and fusion of virtual and geographical agglomerations affect individual's locational choices first, then alter the spatial distribution on the macro-level, meanwhile, dual agglomerations promote the multiple-center developing trend of urban clusters through enhancing their internal connections.Empirical results show that double agglomerations have greatly promoted the multiple-center degree and balanced development of urban clusters.Specifically, dual agglomerations promote the network features of the spatial distribution of urban clusters through increasing node attributes of individual cities, facilitating cross-regional collaboration and accelerating intercity connections.These results provide suggestions and references for the spatial optimizing development of Chinese urban clusters in the digital economic era.
