从巨型城市区域视角审视粤港澳大湾区空间结构

粤港澳大湾区是全球高度城市化地区之一。本文引介巨型城市区域理论来审视粤港澳大湾区的空间结构发展,从边界、功能、核心区、区域基础设施4个维度进行分析。未来粤港澳大湾区将呈现四大发展趋势：一是去边界化趋势显著,大湾区内部边界地区将快速发展;二是产业区将成为网络化的功能区块,并取代城市成为地区参与全球竞争的基本单元;三是广佛、港深两大核心区将形成;四是轨道公交化趋势,大湾区共享交通枢纽与公服设施。按发展趋势预测,未来粤港澳大湾区空间结构将形成“两核+若干功能区”的新格局。

Understanding the Guangdong-Hong Kong-Macao Greater Bay Area from the perspective of mega-city region

The Guangdong-Hong Kong-Macao Greater Bay Area is one of the most urbanized city regions in the world. This study aimed to understand the development of the Guangdong-Hong Kong-Macao Greater Bay Area by applying the theoretical framework of mega-city region. We regarded the Guangdong-Hong Kong-Macao Greater Bay Area as a mega-city region and analyzed its spatial structure from four dimensions: intraregional boundaries, functional network, core area, and regional infrastructure integration. Four development trends were identified: (1) Boundary effect is reducing remarkably and border areas will grow rapidly inside the Greater Bay Area. (2) Industrial clusters become functional areas in a functional network, replacing cities to be the basic unit in global competition. (3) Two core areas can be identified, including the Guangzhou-Foshan core area and the Hong Kong-Shenzhen core area. (4) Rail transit station density tends to increase and a global transportation hub is emerging, which make it convenient for people in the Greater Bay Area to share transportation hub and public service facilities. In the end, the article presents a vision of spatial structure for the Guangdong-Hong Kong-Macao Greater Bay Area, concluding that this mega-city region will form a new structure of 'two cores and functional areas.'
