Using inter-town network analysis in city system planning: A case study of Hubei Province in China

Connection among cities is currently a central issue in regional development. However, relatively few studies have investigated the multi-scale characteristics of inter-city connection and its spatial implications for concrete city system planning. This paper adopts a multi-scalar analytical framework from the perspective of inter-town networks to reexamine this issue. Using 1034 towns in Hubei Province in China as the case-study area, this paper constructs a Hubei Province inter-town network (HBTN) through the radiation model and spatial accessibility and subsequently analyzes the network structure at the macro, medium and micro levels. Corresponding practical policies are provided based on the findings. The results are highlighted below: (1) The HBTN exhibits scale-free and small-world mixing properties; (2) The modular structure of HBTN is apparent. Inter-module connections in the east, central, and west present star-shape, web-like, and loose characteristics, respectively; the corresponding strategies are coordinated development, long-term cooperation and transportation improvement; (3) Five roles of towns were identified in the HBTN. Linking provincial hubs is an effective solution for different modules to achieve powerful alliances. Jingmen, Xiangyang, and Yichang should transform their roles to connector hubs to improve integrative development. This study validated the applicability of the network analysis method to concrete city system planning. The results could help us to assist and optimize management efforts for regional development.
