摘　　要：基于长三角地区2013—2022年的面板数据,对其城市竞争力进行水平测度和时空规律分析.Kernel密度估计三维图表明,长三角地区的城市竞争力水平在2013—2022年间呈现出普遍的上升趋势.然而,通过Dagum基尼系数的比较,发现该区域的城市竞争力存在显著的区域差异,且这种差异主要源自省份间的不同,特别是安徽与江苏两省之间的差异对整体省份间差异的贡献尤为突出.进一步利用莫兰指数对城市竞争力的空间演化特征进行探究,结果显示长三角地区的城市竞争力集聚现象有所缓解,但空间分布整体上仍不均衡.The level measurement and temporal-spatial pattern analysis of urban competitiveness in the Yangtze River Delta region are conducted based on panel data from 2013 to 2022.The three-dimensional graph of Kernel density estimation shows that the competitiveness level of cities in the Yangtze River Delta region has shown a general upward trend from 2013 to 2022.However,through a comparison of the Dagum Gini coefficient,it is found that there is a significant regional disparity in urban competitiveness in the Yangtze River Delta region,and this disparity mainly comes from differences among provinces,the contribution of the differences between Anhui Province and Jiangsu Province to the overall inter provincial differences is particularly prominent.Furthermore,the Moran index is used to explore the spatial evolution characteristics of urban competitiveness,the results show that the agglomeration phenomenon of urban competitiveness in the Yangtze River Delta region has eased,but the overall spatial distribution is still uneven.
