虚实相生:电商冲击下的城市中心体系分异

COEXISTENCE OF VIRTUALITY AND REALITY:DIFFERENTIATION OF URBAN CENTRAL SYSTEM UNDER THE IMPACT OF E-COMMERCE

电子商务的发展使得网络消费迅速扩展,并对传统的以空间区位为基础的中心体系形成了冲击。在网络的虚拟消费与空间的实体消费的交互影响,产生了中心体系的分异,体现在物流中心的转移、特色功能的分化、业态类型的更迭等多个方面。基于此,本文以南京为例,借助POI大数据,对城市虚拟消费中心和实体消费中心的布局、结构等进行了研究,发现了城市中心体系的分异现象,以及虚拟消费中心和实体消费中心相互交织的相生现象,并进一步揭示了主中心持续极化、专业次中心和特殊功能区分异、小型中心不断涌现的特征规律,为电子商务冲击下,城市公共服务体系的规划应对提供参考与借鉴。

The development of e-commerce has led to the rapid expansion of online consumption,and has formed an impact on the traditional central system based on spatial location.The interaction between the virtual consumption on the internet and the physical consumption space has produced differentiation of the central system,which is reflected in the relocation of the logistics center,the differentiation of featured functions,the change of industrial types,and so on.Based on this,taking Nanjing as an example,with the help of POI big data,this paper studies the layout and structure of the urban virtual consumption center and the physical consumption center,finds the differentiation of the urban central system and the mutual interweaving of the virtual consumption center and the physical consumption center,and further reveals the characteristic laws of the continuous polarization of the main center,the differentiation of professional sub centers and special functions,and the continuous emergence of small centers,which provides reference for the planning of urban public service system under the impact of e-commerce.
