摘要
随着全球化和信息化的推进,中国城市群内部联系成为区域研究的热点。本文以赛博空间为视角,以我国三大城市群城市的豆瓣同城数据为对象,通过点度分布、对称性、群集性和匹配性等指标对城市网络进行描绘与测度。实证研究显示:我国三大城市群的城市网络在赛博空间中呈现出多核心网络状的特征,北京、石家庄、天津、上海、杭州、南京、广州和深圳分别成为城市群中的枢纽或者次枢纽城市。高等级城市吸引人口集聚与跨越城市的联系增强的现象是同时存在的,一般城市在互动型活动上凭借其城市特色,同样吸引周边城市的关注。研究最后针对不同层级城市的活动容纳特征提出了相关规划建议。
In the human geography territory, Polynet Project which was led by Pain and Hall has raised the trend of city net- work research within urban agglomeration and city network research has become a key study issue as the globalization and in- formatization deepen. Many scholars have examined the city network in various ways which include corporation network, traf- fic network, infrastructure network and science network. However, little attention is paid on the network of information com- munication technology (ICT). People-Orient characteristic is the most distinguishing feature of ICT network comparing to the previous city network research. In this network, we can clearly tell the choice of every common people, Douban-event as one of the most mature web 2.0 service product in China may well present the cyber space especially the leisure activity on the In- temet. Consequently, by using the cross-city activities happened in Douban-Event, this research examine the city networks of three major urban agglomerations of China (Pearl River Delta, Yangtze River Delta, Beijing-Tianjin-Hebei) in the perspective of cyberspace. By distinguishing users' attentions on the events happen in the cities which they do not live in, we form the ma- trix of urban agglomeration as the database of city network. Furthermore, clustering index, degree distribution and symmetry index are involved to examine the attribute of it. In cyberspace, the city networks of these urban agglomeration represent the Multi-Core Network Structure while Beijing, Shijiazhuang, Tianjin, Shanghai, Hangzhou, Nanjing, Guangzhou and Shenzhen become the hub city or sub-hub city in its own region. They attract more residents' attentions than the real world. The linkage of hub cities and secondary cities form the basic framework of the city network. Moreover, the concentration in the high-level cities and the connection of different-level cities exist at the same time. The hub cities concentrate the most of the cross-city ac- tivities both in performing activities and interact activities while some common cities attract the neighboring cities' attentions in interactive activities because of their city features.
