摘要
通过与普通铁路网进行对比分析,利用修正的引力模型与社会网络分析法,考察全面高铁时代下中国省域中心城市空间关联网络结构变化。结果表明:在高铁交通网中,省域中心城市的经济引力值大幅度上升,不同地区的提升幅度存在差异,由大到小依次为西部、东部、中部和东北;整体网络密度、点入度均值和点出度均值、中心度均值都明显提升,城市表现存在差异,合肥、长沙和天津提升相对显著;子群中城市变化不大,但子群内部、子群与子群之间密度却发生了变化。全面高铁时代,要素在省域中心城市之间流动加速,这要求各省域中心城市要在更大空间谋划产业分工,分享高铁经济红利,要重新考察各省域中心城市角色定位,从全国"一盘棋"战略,推动高铁网络经济发展。
Using the method of social network analysis and the modified gravity model through the comparison ofordinary railway network,this paper explores the changes of spatial correlation network structure of China＇s provincialcenter cities in the era of comprehensive high-speed rail. The results show that： In the high-speed rail network,theeconomic gravity values of capital cities increase significantly. There exist differences in different regions on theincreasing rate of economic gravity values, among which capital cities in western region increase the most then theeastern region, next the central region, finally the northeast region; the network density, the mean values ofin-degree, out-degree and degree centrality are on the noticeable rise. Different cities show the differences inincreasing rate,among which Hefei,Changsha and Tianjin increase remarkably; the members of each subgroup changelittle,while the density of each subgroup within and the density among different subgroups have a great change. Inthe era of comprehensive high-speed rail, the flow of factors has been accelerated among different capital cities.Therefore,it is necessary for the center cities to plan the division of industries in a larger space,share high-speedrail economic dividend and re-examine their own positions to promote the economic development of high-speed railfrom the angle of national＂a board of chess＂.
