本文综合运用交通网络和经济网络来研究中国城市体系的空间结构,并在此基础上对二者进行对比分析,为中国城市体系网络研究提供了新思路。研究结果表明:我国目前已形成以北京、上海、广州、重庆为中心的菱形城市网络基本骨架,城市间的空间联系呈现由中心城市向外依次递减的空间圈层结构;相对而言,交通网络有助于推进区域均衡发展,经济网络则有助于形成经济集聚,将二者结合起来研究,可为促进中国经济发展“在集聚中走向平衡”提供理论参考。 In this paper, we study the spatial structure of China’s urban system by using transportation network and economic network. On the basis of this, we make a comparative analysis of the two, which provides a new idea for the research of China’s urban system network. The results show that: At present, China has formed the basic skeleton of rhombic city network with Beijing, Shanghai, Guangzhou and Chongqing as the center, and the spatial connection between cities presents the spatial circle structure decreasing gradually from the central city. In contrast, the transportation network It will help to promote the balanced development of the region. Economic networks will help to form economic agglomeration. The combination of the two will help provide a theoretical reference for promoting China’s economic development and moving towards equilibrium in agglomeration.
