The COVID-19 pandemic has a huge impact on China's economic and social development.Examining the changes in the level of economic resilience of the Yangtze River Delta region in response to a major public health event is beneficial for the post ep-idemic economic recovery and high-quality development of Chinese urban agglomerations.This paper explored the spatio-temporal e-volution characteristics of regional economic resilience in the Yangtze River Delta region,using the multi-indicator core variable meth-od to under the impact of the epidemic from two process dimensions of resistance and recovery,and identified the key influencing factors by using the geographical detector model.The results showed that:①The overall economic resilience of the Yangtze River Delta region showed a trend of rising first and then falling,belonging to the type of high resistance-high recovery.The overall level of regional eco-nomic resilience was high,in which the GDP economic resilience performance was the most stable.②The provincial differences in the dynamic evolution of the regional economic resilience were significant,indicating the clustering distribution characteristics with the de-velopment of east-west regions being unbalanced.The number of cities with low toughness level in the recovery stage had increased significantly.The gap in toughness level between cities had narrowed.③Industrial structure,innovation and transformation,government management,and financial support were the main driving factors for the improvement of economic resilience.The negative impacts in-duced by the pandemic disturbance were more prominent.
