Abstract In the human geography territory, Polynet Project which was led by Pain and Hall has raised the trend of city network research within urban agglomeration and city network research has become a key study issue as the globalization and informatization deepen. Many scholars have examined the city network in various ways which include corporation network, traffic network, infrastructure network and science network. However, little attention is paid on the network of information communication 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 Internet. 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 matrix 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 activities both in performing activities and interact activities while some common cities attract the neighboring cities' attentions in interactive activities because of their city features.
