摘要:

巨型城市区的概念于1999年由P. Hall提出,是中心大城市向新的或临近的较小城市极度扩散后所形成的,是21世纪初正在出现的新城市模式,其概念强调区域在全球化中的作用,并认为城市间高级生产性服务业产生的联系与区域的多中心结构相关联。近年来,长江三角洲作为中国最大的经济核心区,城市发展呈现出新的趋势和特点,上海依托长三角腹地建设全球城市成为共识,以上海为中心的大都市连绵带正在向巨型城市区演变。在介绍巨型城市区的概念的基础上,从多中心、功能性和网络性三个角度对长江三角洲巨型城市区的特征进行了初步分析,并指出长江三角洲巨型城市区是一个多中心网络状的城市区域。

Abstract:

The polycentric Mega-City Regions (MCR) have arisen through a long process of very extended decentralization from big central cities to new or adjacent smaller ones. It is an emergent urban phenomenon in the course of formation at the beginning of the 21st century. The concept of MCR emphasizes the role of the regions with one or more global cities (or world cities) in the globalization process, and considers that the knowledge-intensive producer service business operations and flows are associated with a polycentric pattern of urban development in each MCR. Recently, some new trends and characteristics have risen in the development of cities and towns in the Yangtze River Delta that has been the biggest economic core region of China. It is now universally accepted that Shanghai would become a global city in the context of the Yangtze River Delta and the Metropolitan Interlocking Region with the core of Shanghai being evolving into a Mega-City Region. This paper explores the concept and characteristics of Mega-City Regions, and provides a research on characteristics of the Yangtze River Delta Mega-City Region, which is defined in terms of contiguous FURs. The polycentricity of the MCR is measured by both rank size analysis and functional polycentric analysis. The MCR's functional characteristics are investigated by measuring functional connections between 16 main FURs, and their network characteristics are reflected by highway and railway networks and intra-regional producer service linkages. Further, the polycentricity is measured again by analyzing the network of functional linkages. And it is found that Shanghai, Suzhou, Wuxi and Hangzhou are the four main centers of the MCR. This finding may have some differences between the previous rank size analysis and functional polycentric analysis. Finally, it concluded that the Yangtze River Delta Mega-City Region that has 55 contiguous FURs with a population of more than 80 million and an area of 78,000 km2 is a polycentric network city region.
