【摘要】：核心城市经济增长的极化与扩散效应直接影响城市群增长格局变动,长三角城市群核心城市增长极化效应的演化推动了该城市群由单核心向多中心发展。综合考虑经济规模权重的增长极化指数与经济增长溢出渠道的多元增长极化指数,及增长核心集中度指数等多指标的变化,本文对长三角城市群1995年以来增长格局特征及其演化的定量分析表明各指数基本呈现下降趋势,核心城市极化效应逐渐减弱,而核心城市增长的收敛性特征日益明显;长三角城市群均衡化发展的态势主要源于上海、苏州等地多核心的增长溢出效应带动了城市群内其他城市的快速发展;基于差异化的增长溢出渠道,不同城市发挥着增长核心作用。
[Abstract]:The polarization and diffusion effect of the economic growth of the core city directly affects the change of the growth pattern of the urban agglomeration. The evolution of the polarization effect of the growth polarization effect of the core city agglomeration of the Yangtze River Delta promotes the development of the urban agglomeration from a single core to a multi-center. Considering the changes of the growth polarization index of the economic scale weight, the multiple growth polarization index of the economic growth spillover channel, and the growth core concentration index, the quantitative analysis of the growth pattern characteristics and evolution of the Yangtze River Delta urban agglomeration since 1995 shows that each index basically shows a downward trend, the polarization effect of the core cities is gradually weakened, and the convergence characteristics of the growth of the core cities are becoming more and more obvious. The trend of balanced development of Yangtze River Delta urban agglomeration mainly originates from the multi-core growth spillover effect in Shanghai, Suzhou and other places, which leads to the rapid development of other cities in the urban agglomeration. Based on the differentiated growth spillover channels, different cities play a central role in growth.
