| 摘 要： | 在全球化、信息化背景下,城市之间的竞争已经不再局限于单体城市本身的规模属性,而是越来越取决于城市参与分工协作的地位以及多尺度空间的功能联系,尤其表现在城市网络化、集群化的竞合态势,而城市群已经成为该背景下具有全球意义的空间组合模式。在系统梳理了中西方城市功能地域概念的内在关联基础上,论文认为,中国的城市群概念具有尺度伸缩性,与西方的巨型城市区域、巨型都市区和巨型区域概念是最为接近的。在空间内涵上看,城市群是2个以上城市体系组成的巨型城市地域,是兼具形态连续性和功能内聚力的城市系统,是全球化与本地化显著交互作用的大型经济单元,是当今时代城市与区域分工协作的一种尺度修复。基于此,城市群发育的基本条件主要包括良好的资源环境综合承载能力、大都市区与多个城市系统、地理空间上的邻近性与紧凑性、发达和完善的基础设施网络、深入协调的功能分工与经济联系以及相对一致的社会网络和文化认同。未来,中国城市群研究应更加兼顾形态和功能维度的统一,尤其注重从关系地理与城市网络视角探索城市群的空间集聚效应及其演化规律。 |

| Abstract: | Within the context of globalization and informatization society, inter-city competition is no longer bound to the scalar attributes of individual cities, such as geographic location, administrative hierarchy, population size, and so on, but rather increasingly depends on their positions in the division of labor and multi-scalar spatial functional linkages. Along with the current tendency of urban networking and clustering development, megaregion has become the spatial organization pattern with global significance in response to the present new competition and corporation situation. To understand megaregions in China, the differentiation and relationships between different concepts of urban functional regions in both Chinese and Western urban geography studies were systematically examined. The Chinese native concept of "Chengshiqun", as an urban region with flexible scale, is mostly similar to the concepts of mega-city region, megapolitan area, or megaregion in Western academic literature. To make it simple, we used the concept of megaregion to refer to the Chinese "Chengshiqun" in this article. In terms of the spatial meanings, we argue that a megaregion is: 1) a mega urbanized region consisting of more than two urban systems; 2) an urban system with both morphological continuity and functional cohesion; 3) a mega economic unit produced and shaped through the interaction of globalization and localization; and 4) a type of scale fix in today's urban and regional division and integration of labor. Specifically, the basic conditions for the development of megaregion mainly include high comprehensive carrying capacity of resources and environment, close spatial proximity of the metropolitan area to multiple single urban systems and compactness in geographic space, well-developed infrastructure networks, coordinated functional division and economic linkages, and relatively coherent social network and cultural identity. In future studies, we should pay special attention to exploring the spatial agglomeration effects and evolution of megaregions from the perspectives of relational geography and city network. |
