The Structure Evolution of China's Urban Networks from the Perspective of Flows: Take 2007-2014 as an Example

摘要

China's massive high-speed rail construction in a short time has exerted a huge impact on accessibility and connectivity of cities. As the rise of "Flow space" theory, the impact of high-speed rail construction on urban network is more noteworthy. According to 2007-2014 HSR time schedule data, this paper analyses China's the development of urban network structure influenced by HSR networks. By calculating DIT, RSL, ODIc, ODII indexes, it tries to explore the urban networks structure and changes in the comprehensive Chinese HSR networks. The conclusions are: (1) with the spatial extension of HSR networks, the connectivity of cities was strengthen (2) China's urban system structure connected by HSR networks became more polycentric. (3) Compare to other regions, HSR networks are more completely developed in the Yangzi River Delta region.
