| 摘 要： | 迁徙流作为互联网时代的新产物,信息流、资本流、交通流等流空间的基本载体,能客观地反映城市间地理行为关系,对于刻画城市网络结构具有重要意义。基于地级以上城市的百度迁徙大数据,本文尝试从全域和净迁徙的视角探索研究中国城市网络结构特征,对其网络的层级、关联关系和影响因素等进行挖掘提取。研究发现：① 全国城市网络呈现出稳定的、层级明确的三棱锥四顶点“钻石型”结构,与主要城市群的经济规模空间分布相吻合;② 区域网络表现出向高级别行政中心集聚的“核心—外围”放射状结构;③ 以省会城市为核心的典型小世界特征比较凸出,小世界网络的可达性和连通性较高;周口、阜阳、赣州、上饶、重庆等作为主要劳动力输出型城市,深圳、东莞、广州、北京、上海等城市成为了主要的外来人口聚集地,并形成了对应的人口就近输送网络关系;④ 城市的行政地位、经济规模、交通枢纽建设、劳动力资源等因素都对其网络控制力和影响力起到了决定性作用。最后,研究结合中国城市网络结构特征及其主要影响因素,提出相关政策建议,以期为中国城市网络结构均衡发展与建设提供借鉴依据。

| Abstract: | As a new product of the Internet era, migration flowed is the basic carrier of information flow, capital flow, traffic flow and other flow space. It can objectively reflect the geographical behavior relationship between cities, and it is of great significance to depict the urban network structure. Based on the big data of Baidu migration in cities above prefecture level, this paper attempts to explore and study the characteristics of urban network structure in China from the perspective of full time and net migration, and extracts the hierarchy, association and influencing factors of urban network. The results show that: the national urban network presents a stable and hierarchical pyramid and four vertex "diamond" structure, which is consistent with the spatial distribution of economic scale of major urban agglomerations; the regional network shows the core periphery radial structure of agglomeration to high-level administrative centers. The typical small world characteristics with provincial capital cities as the core are relatively prominent, and the accessibility and connectivity of small world network are high. As far as cities are concerned, Zhoukou, Fuyang, Ganzhou, Shangrao and Chongqing are the main export areas of population resources, while Shenzhen, Dongguan, Guangzhou, Beijing and Shanghai have become the main gathering places of migrant population, and the corresponding population transportation network has been formed. Administrative status, economic scale, transportation hub construction, population resources and other factors all play a decisive role in the control and influence of cities in the urban network. Finally, combined with the characteristics of China's urban network structure and its main influencing factors, the paper puts forward relevant policy suggestions, in order to provide reference for the balanced development and construction of China's urban network structure. |
