中文摘要：

基于中国大陆27个主要城市间高铁运行网络,从中国铁路客户服务中心（www.12306.cn）上获得城市间的高铁（含动车）客运班次数据,建立27×27的发送-到达矩阵,采用社会网络分析方法中的中心性分析法和因子分析法,对27个主要城市的中心性和网络空间格局进行了分析。研究表明：从中心性分析可知北京、武汉、上海三个城市在高铁网络中的中心性非常高,北京作为政治中心,武汉作为交通中心,上海作为经济中心,决定了它们的中心地位。从因子分析看我国目前的高铁网络由七个子网络构成：沈大、京津济、沪宁杭、福厦、郑石-郑西、武广、成渝,覆盖东北地区、华北地区、华东地区、中南地区（河南、湖北、湖南、广东、广西）、西南地区,但是西北地区还没有形成高铁网络。

英文摘要：

Based on the high speed railway network of 27 primary cities in mainland China and the data of operating hours of intercity high speed trains acquired from www.12306.cn, the 27×27 delivering—arriving matrix is built. The centrality and network spatial pattern are analyzed by centrality analysis and factor analysis of the social network analysis（SNA）. The conclusion is that Beijing, Wuhan and Shanghai are three cities of very high centrality from centrality analysis, which is due to the fact that Beijing is a political center, Wuhan the traffic center and Shanghai the economic center. From factor analysis, the high speed railway network of the primary cities in China consists of seven sub-networks, including Shenyang-Dalian, Beijing-Tianjin-Jinan, Shanghai-Nanjing-Hangzhou, Fuzhou-Xiamen,Zhengzhou-Shijiazhuang-Xi＇an, Wuhan-Guangzhou, Chengdu-Chongqing. They cover most areas in mainland China except the Northwest China.
