| 摘 要： | 功能多中心是21世纪以来出现的一种崭新的区域空间结构,在经济全球化与新劳动分工的影响下正显示出巨大的经济力量。本文借助社会网络分析工具与全新的功能多中心指数综合分析判断本区域功能多中心的发展趋势,并结合极化-扩散效应的演算进一步验证前述结果的科学性.研究认为:长三角地区以核心城市为动力源,联合其他中小城市协同发展的态势逐步显现;长三角地区的空间结构呈现出很强的等级规模分布,区域城镇体系十分完整,具备向功能多中心发展的基本条件;长三角地区功能多中心是极化效应和扩散效应共同作用的结果,前者多来自区域高端产业的大规模集聚,后者则来自区域中低端制造业的大规模转移.

| Abstract: | Functional polycentricity is a new regional spatial structure in the world in the 21st century and it will show a great economic power under the influence of economic globalization and the new labor division. In this paper we judge whether the functional polycentricity exists in Yangtze River delta (YRD) using the method of social network analysis and functional polycentricity index. Then we calculate the polarization effect and diffusion effect to further certify the former conclusion. The results are given below. YRD gradually shows a trend of coordinated development ——the core cities as the power source combined with other small and medium-sized cities. YRD shows a rank-size distribution under the constraints of the urban hierarchy system, which is the base of a functional polycentricity. The functional polycentricity in YRD is the result of regional polarization effect and diffusion effect. The former effect comes from the large-scale gathering of APS (advanced producer services), and the latter comes from the regional spread of basic manufactures. |
