摘　　要：基于中国大型社交网络人际社交关系,以新浪微博为例,构建中国城际地理社交关系网络,提出以城市社交通量指数、城际社交通量指数和城市社交集聚指数为主要评价指标,借此评价城市社交活跃度与影响力、城际社交强度以及城市社交偏好性,分析中国城市社交网络的拓扑特征.研究显示,中国城际社交网络具有明显的全局异构性和局部异构性,在地理空间分布上呈现空间分异现象.城市的社交通量与集聚指数呈较强的正相关,深刻影响中国社会文明进程的一二线城市属于社交寡占型城市,与外界交流相比中小城市社交偏好更为集聚.该研究可为探讨线上网络空间与线下现实空间的映射关系,揭示社交网络信息流的地理空间传播路径、预测网络热点事件时空演化趋势及时空影响范围提供理论依据.Based on the aggregated inter-person social relationships collected from the largest social network website in China-SINA micro-blog, an inter-city geographic social network （GSN） is built in this research. To evaluate the city social activity and influence, strength of inter-city social linkages, and city social preferences separately, three indices of inter-city social connectivity, city social connectivity, and concentration of social preference are presen-ted. By using the indices, this paper attempts to analyze the topological characteristics and map the spatial distribu-tion of inter-city social interactions in China. Results show that strong system and local heterogeneities exist in the in-ter-city GSN, social connectivity is significantly imbalanced among cities and city linkages in China. Also it was found that city social connectivity is positively related with the city social preferences, outside communication in most of the tier one and tier two cities are much more concentrated compared to the other cities in China. This research can help us to understand the mapping relationships between online and offline social network, reveal the transmis-sion routes of information flow, and forecast the spatio-temporal evolutions of hot social incidents.
