【摘要】：基于复杂网络理论,从网络的视角构建均衡性指标——网络区位系数,并依次从点、线、面三个层面从整体上评价2007年普通铁路和2015年高速铁路网络发展格局;其次,利用偏移—分享模型,研究464个高铁城市在高铁网络格局中的地位变化,揭示高铁建设发展过程中的非均衡发展现象。结果显示:(1)铁路网络结构由"一枝独秀"到"三足鼎立",高铁网络覆盖了大部分人口规模超200万人的都市区,网络联系呈现纵向联系强、横向联系弱的特点;(2)大部分之前未开通普通铁路而直接纳入高铁网络的城市位于长江流域和东南沿海,这类城市较少出现在华北和东北地区;(3)高铁网络区位优势由东向西呈地带性递减,东中部中心城市的优势突出,西部中心城市的优势不明显且整体呈现"低水平均衡"格局;(4)城市行政级别越高,高铁覆盖率越高,但在东部地区,高铁结构由"等级化"向"扁平化"发展,中小城市已率先获益。
[Abstract]:Based on the complex network theory, this paper constructs the equilibrium index, the network location coefficient, from the perspective of the network, and evaluates the development pattern of the ordinary railway network in 2007 and the high-speed railway network in 2015 from the point, line and surface levels in turn. By using the offset-sharing model, the status of 464 high-speed railway cities in the high-speed rail network pattern is studied, and the unbalanced development phenomenon in the development of high-speed rail construction is revealed. The results show that the network structure of the railway has changed from "one outshine" to "three legs." the high-speed rail network covers the metropolitan areas with a large population of more than 2 million people, and the network links show a strong vertical connection. Most of the cities that had not opened ordinary railways before and directly incorporated into the high-speed rail network are located in the Yangtze River Basin and the southeast coast. These cities rarely appear in North China and Northeast China.) the geographical advantages of the high-speed rail network decrease from east to west, and the central cities in the east and central regions have the advantages. The superiority of the central cities in the west is not obvious and the overall situation is "low level equilibrium". The higher the administrative level of the cities, the higher the high-speed rail coverage rate. However, in the eastern region, the high-speed rail structure has developed from "hierarchy" to "flattening". Small and medium-sized cities have taken the lead in benefiting.
