从社交网络到地理网络——基于南京市高校新浪微博用户的分析

From Social Network to Geographical Network:A Case Study of College Sina Weibo Users in Nanjing

面对网络时代下人类信息传递和社交方式的革命性突破,文章以南京市高校师生的新浪微博用户作为抽样源群体,但在研究思路上又不局限于该师生样本,而是以各样本为原点来分别串联、圈定和分析其跨区域的网络社交关系;继而以"社交网络+地理网络"作为贯穿性主题词和关键指标,按"总体把握"和"师生比较"两个层面展开高校的网络社交特征与时空规律探讨,进而通过"社交关系+社交频率"组合形成的网络关联度对其地理网络进行分析,并与"南京总体微博用户"的地理网络特征和规律的相关研究成果(同样以南京市为基点)进行比较,得出高校社交网络在空间规模上聚集度高、等级差异明显,在关联强度上局限性大、不均衡性强等差异性特征,并剖析得出高校社交网络机制形成的地域植根性、社会经济发展差异性,以及高校群体特有的教育资源(学术前沿)空间分布、群体自身特殊性等动因。

Faced with the revolutionary breakthrough of human information transmission and social communication mode in the network era,this paper takes Sina Weibo users of teachers and students in Nanjing universities as the sampling source group.However,the research idea is not limited to the samples of teachers and students.Instead,the cross-regional network social relations are connected,defined and analyzed with each sample as the origin.Which in turn to"social network+geographical network"as penetrability keywords and key indicators,the social network characteristics and spatial and temporal laws of colleges are discussed according to"overall grasp"and"teacher-student comparison",and then through the"social relationship+social frequency"combination form called network correlation degree to analyze its geographical network.Compared with the relevant research results of the geographical network characteristics and rules of"Nanjing overall Weibo users"(also based on Nanjing),it is concluded that the social network of colleges and universities has high aggregation degree in space scale,obvious difference in grade,great limitation in connection strength and strong imbalance.And it also analyzes the regional roots and social and economic development differences formed by the mechanism of social network in colleges and universities,as well as the special educational resources(academic frontier)spatial distribution and the particularity of the groups,which may provide a glimpse into the tip of the iceberg of large social network communities.
