Research on characteristics and influence mechanism of urban-resilience in the Yangtze River Delta under high-quality perspective
Urban resilience improvement of the cities from the Yangtze River Delta region,as an important growth pole for the coun-try's high-quality economic development,has great significance for promoting high-quality coordinated development and building ur-ban safety in that region.Using the entropy method,Theil Index,Random Forest and other methods,this paper analyzed the spatio-tem-poral evolution characteristics and influencing factors of 41 prefecture-level cities'urban resilience in the Yangtze River Delta region from 2010 to 2020.The results showed that:①The overall resilience of high-quality cities in the Yangtze River Delta,the development level of urban resilience,and the innovation index of urban resilience,from 2010 to 2020,all showed an upward trend and the innovation index showed the fastest growth rate of 196％.②Theil index and Gini coefficient in the study area decreased from 2010 to 2020,indica-ting that urban resilience difference in the study area decreased as a whole.③From the perspective of spatial evolution,the study area showed obvious differentiation,which is its urban toughness grade structure presented a decreasing feature along the central area,form-ing a spatial distribution with Shanghai and Suzhou as HH agglomeration areas,and northern Anhui and Northern Jiangsu as LL charac-teristics.④Government policies,innovation,science and technology,and regional economic development were the main influencing mechanisms of high-quality urban resilience development,such as talent aggregation,enterprise development and policy environment.
