摘要
我国高速铁路网络正逐步形成。从铁路系统的基础设施层面,以高速铁路车站为节点,相邻的两个站点间的轨道为边,构建高速铁路网。基于复杂网络理论,计算节点度及其分布规律、集聚系数、平均路径长度、介数等指标;在此基础上,分析高速铁路站点分布与地区人口、人均GDP、三大产业的关系。研究结果表明:网络呈现无标度特性,不具有小世界性;高铁站点的单位服务人数与地区人均GDP具有一定相关性;与第一产业产值相关性不大,与第二、三产业的耦合度较第一产业有所提高。
The Chinese high-speed railway is being formed, From the aspect of infrastructure level, taking a high-speed rail station site as the node, the track between two sites adjacent as the edge, to build the high-speed rail network. Based on complex networks theory, using ucinet to compute node degree and distribution, clustering coefficient, average path length, betweenness and other indicators. On this basis, the paper analyzes the relationship between the network structure with per capita GDP and the three major industries values. The results show that： the network presents the scaling prop- erties while doesn＇t have the small world character. The sta- tion＇s service unit number has a certain correlation with per capita GDP, and it has low correlation with first industrial output. Comparing the first industrial output, there is higher degree of association with the second industrial and tertiary industrial output.
