Based on the panel data of 27 cities in the Yangtze River Delta from 2013 to 2021, this paper evaluates the high-quality development level of the Yangtze River Delta by constructing an evaluation index system of high-quality economic development. We use the spatial econometric model to analyze the spatial spillover effect of financial development in the Yangtze River Delta on high-quality economic development. The findings are as follows: (1) The high-quality development level of the Yangtze River Delta has steadily improved. (2) The high quality development of the Yangtze River Delta has a phenomenon of spatial aggregation, and the comprehensive score of the east and south is significantly higher than that of the west and north. (3) The high-quality development of the Yangtze River Delta has a spatial spillover effect. (4) Financial scale can promote high-quality economic development and has a positive spillover effect.
