| 摘 要： | “经济—空间”视角下城市中心体系的理论与实证研究之间缺少相互衔接的分析框架。论文通过对经典理论的系统归纳与演绎,建立整体视角下理解城市中心体系形成与发展的理论框架,将城市中心体系的发展规律概括为空间竞争和空间联系2个机制,体现在本地服务功能和非本地功能的空间组织过程,分别形成等级网状结构和专业化点状结构,并相互融合形成“半网格”的城市中心体系,扮演着本地与宏观区域结构之间的“转换发动机”。最后探讨了对实证研究的若干启示,提出城市中心的定义和识别方法应注意与理论研究相互衔接;认为城市中心的本地/非本地功能特征及相应的发展机制亟待实证;认为中心及其空间影响的调控潜力是制定规划政策的前提。

| Abstract: | Under the "economic space" perspective, theories and empirical studies regarding urban centers system have developed in isolation from each other. This study aimed at filling this gap with a synthesized theoretical framework. Based on a general survey of theoretical models, we argued that the formation and development of urban centers system are mainly determined by two mechanisms—spatial competition and spatial connection, generating the spatial organization of local and non-local services respectively. Then we characterized the urban centers as a "semi-lattice" system that any center in a tree-structure of local service centers could be linked to higher-level centers or even global cities by non-local functions such as those derived from the space of flow. After an in-depth discussion of this framework, we proposed several research implications regarding empirical studies. We argued that empirical identification of urban centers should be consistent with theoretical concepts; reflection from empirical studies should be further linked to the refinement of the framework; and the potential of planning intervention on centers and their spatial effects is the premise of spatial policies. |
