摘要
认知信息空间中城市网络的组织与结构特征，对预测在网络信息技术影响下的区域城市体系动态演化等具有重要的意义。引入社会网络分析方法，尝试探究基于微博信息空间的城市网络中不同节点的中心性与对等性，网络整体的一致性以及区域城市组团模式。以51个城市组成的中国主干城市网络为例，研究表明信息空间的城市网络与实体空间中经济网络、交通网络的高密度聚集区地理分布具有一定的相似性。同时，信息空间城市网络的整合一致性高、分支少等结构特征，又体现出信息空间的虚实复合性特征。社会网络分析方法提供了信息空间城市网络结构的重要甄别途径。与其他分析手段有机结合，以获得更加系统和动态的测度结果将是未来研究的方向。
It has great significance for predicting the evolution of regional city system structure trader the influence of ICTs to acknowledge the organizational and structural characteristics of the city network in the cyberspace. This research conclude the centrality and equivalency of different nodes in the city network based on the micro-blog cyberspace, the consistency of the overall network and various urban cluster modes through social network analysis such as centrality analysis, core-periphery analysis and cohesive subgroup analysis. Take the 51-scaled Chinese backbone city network based on the cyberspace as an example. Social network analysis shows that the degree centrality and betweenness centrality demonstrates some differences and complementarities, and there are obvious core-periphery structure characteristics. Beijing, Shanghai, Shenzhen and Guangzhou make up the core circle of Chinese city network based on the cyberspace. The city communities break the single pattern which is based on the geographical distance and takes economic ties as the link. Comparing with city networks based on different kinds of infrastructures, further conclusions of the study can be drew as： The city network based on the cyberspace is similar with economic network and transportation network in the real space in terms of geographical distribution of contact density accumulating area. In addition, city network based on the cyberspace reveals characteristics of high integrated consistency and few branches, which reflects the virtual combined with reality feature of the cyberspace. The social network analysis provides important screening approach of city network structure based on the cyberspace. However, to obtain a more systematic and dynamic result, it requires a combination of other analytical means, which is the direction of further exploration.
