基于教育网络的上海城市网络空间结构研究

The Spatial Structure of Shanghai City Network based on Education Network

利用2016年上海市教育机构的相关数据,运用连锁网络模型、社会网络分析方法以及ArcGIS空间分析方法测度了上海城市网络的空间结构特征。研究发现:①整个网络具有较强的集聚性,节点中心性空间分异显著,呈现出小世界效应的特征。②网络层级鲜明,五角场街道、徐家汇街道为上海教育网络的集聚中心,处于城市网络的最高层级。整个城市网络呈现四边形架构的空间格局,五角场街道-徐家汇街道-张江镇-江川路街道为网络的核心架构顶点。③通过QAP回归分析发现,人口因素、地理距离、交通通达性、产业集聚、名牌效应以及商务经济发展水平是上海城市网络形成的重要影响因素,对城市教育网络的扩展具有促进作用。

Based on the data of Shanghai educational institutions in 2016,the spatial structure characteristics of Shanghai city network is studied with the interlocking network model,social network and ArcGIS spatial analysis.The research finds that:1)The whole network presents strong a clustering tendency;three node centralities show quite distinct spatial patterns;the small-world effect is significant.2)The network has a hierarchy structure:Wujiaochang Street and Xujiahui Street are the agglomeration centers of Shanghai education network,occupying the highest level of the city network.In addition,the whole city network presents a quadrilateral spatial structure with four vertices of Wujiaochang Street,Xujiahui Street,Zhangjiang Town and Jiangchuanlu Street.3)QAP regression analysis shows that population,geographical distance,traffic accessibility,industrial agglomeration,brand effect and business development are important determinants of city network of Shanghai,promoting the expansion of urban education network.
