摘要: 在经济极化研究的基础上, 首先利用ER指数和TW指数对长三角1990-2010 年的经济极化趋势进行测度, 从整体上把握区域经济极化的演变过程;其次, 选取1997、2001、2006 和2010 年这4 个典型年份, 从极化效应与扩散效应的角度对长三角地区的经济极化过程进行科学分析, 总结其空间格局的演化规律。研究发现:①从极化指数的动态演变过程来看, 长三角地区的经济极化水平在1990-2010 年间呈现出波动上升的变化趋势, 并通过极化的初始定义对上述论断进行了验证;②从极化理论的两大效应来看, 长三角地区的极化效应在研究时段内经历了一个先扩大再缩小的变化过程, 而其扩散效应在研究时段内是逐渐增强的;③从经济极化的空间格局来看, 长三角地区在近10 多年的时间里呈现出“箭头”型—“Z”字型—“M”字型—“区”字型的变化过程, 未来借助相关基础设施束扩散效应的增强, 本地区空间格局有望向网络型转变。

Abstract: Based on the studies on economic polarization previously done by others, the ER index and TW index are used to measure the trend of economic polarization in the Yangtze River Delta from 1990 to 2010, and the overall process of economic polarization during the period of the study is analyzed. Then, from the perspective of polarization effect and diffusion effect, the processes of economic polarization in the Yangtze River Delta in four typical turning-point years (1997, 2001, 2006 and 2010) are analyzed, and the ways of economic spatial evolution are preliminarily summarized. The study concludes that: (1) the dynamic process of polarization indexes’evolution indicates that the economic polarization level of the Yangtze River Delta displays a rising trend from 1990 to 2010 with fluctuations, and the conclusion on economic polarization has been supported by the observations confirming the definition of the concept itself:“disappearing middle class”. (2) As far as the two effects of the polarization theory are concerned, the polarization effect of the Yangtze River Delta first expands, and then shrinks during the period of the study, whereas the diffusion effect gradually increases throughout the time period. (3) As more and more industrial enterprises are being relocated or transformed, the trend of economic polarization in the whole region begins to be attenuated and economies gradually expand to the periphery areas, hence in recent 10 years the economies of Yangtze River Delta show a transition from“arrow”type to“Z” type to“M”type to“区”type (a Chinese character meaning“zone”). Eventually the spatial pattern of the region ’s economies will be transformed into a network type, driven by the diffusion effects of the development of infrastructure beams.
