摘要
文章选取 2006-2020 年长三角城市群 27 个城市的面板数据,对长三角城市群城市经济韧性进行测度,采用Dagum基尼系数分解法、K-Means聚类法及莫兰指数分别探究长三角城市群城市经济韧性水平的差异化特征、空间演变过程及空间集散特征,最后运用空间杜宾模型进行影响因素分析.研究发现:(1)在样本期内,长三角城市群 27 个城市的经济韧性水平总体呈上升趋势;(2)江苏省与浙江省的经济韧性差异最小,上海市与安徽省的经济韧性差异最大,且各省市间经济韧性的差异逐渐趋于稳定;(3)长三角城市群的城市经济韧性具体表现为以上海市为核心的"中心外围"格局;(4)城市经济韧性呈现明显的空间相关性和集聚特征,由高高集聚和低低集聚为主的城市经济韧性空间关联模式逐渐演化为多样类型;(5)投资、文化建设、社会信息化程度、行政调控力和环境治理对长三角城市群城市经济韧性具有显著的正向影响.
Abstract
The article selects panel data from 27 cities in the Yangtze River Delta urban agglomeration from 2006 to 2020 to measure the economic resilience of cities in the region.The Dagum Gini coefficient decomposition method,K-Means clustering method,and Moran index are used to explore the differential characteristics,spatial evolution process,and spatial distribution characteristics of urban economic resilience.Finally,the spatial Durbin model is used to analyze the influencing factors.The study found that during the sample period,the economic resilience of 27 cities in the Yangtze River Delta showed an upward trend;The difference in economic resilience between Jiangsu Province and Zhejiang Province is the smallest,while the difference in economic resilience between Shanghai and Anhui Province is the largest.The differences in economic resilience between provinces and cities are gradually stabilizing;The urban economic resilience of the Yangtze River Delta urban agglomeration is specifically manifested in the"central periphery"pattern with Shanghai as the core;The urban economic resilience shows obvious spatial correlation and agglomeration characteristics,and the spatial correlation mode of urban economic resilience,mainly consisting of high high agglomeration and low low agglomeration,has gradually evolved into various types.Investment,cultural construction,level of social informatization,administrative regulation,and environmental governance have a significant positive impact on urban economic resilience.
