Based on the panel data of a total of 25 prefecture-level cities in the four major metropolitan areas in China's Yangtze River Delta region from 2003 to 2019, the Dubin model of three types of spatial weight matrix is used to compare and explore the impact effect and mechanism of nancial agglomeration on the coordinated development of ecological green. The results show that, rst, the positive local and neighborhood effects of nancial agglomeration on the coordinated development of ecological green are mainly re ected in the Hefei, Hangzhou and Shanghai metropolitan areas, and the intensity of the effect decreases sequentially. Information transfer and technology correlation are important mechanisms to improve the local effect of nancial agglomeration, and the neighborhood effect varies from metropolitan area to a metropolitan area. Second, in addition to the adverse impact of the concentration of nancial personnel on the integration of ecological green, the agglomeration of securities, banking and insurance industries can release the "green driving potential energy", and the intensity of contribution gradually weakens. Third, the radiation effect of Shanghai's nancial agglomeration is the strongest, Nanjing has a "U" shaped impact, Hangzhou has an inverted "U" shaped impact, and Hefei does not play a role. HighlightsExplore the impact of nancial agglomeration on the coordinated development of ecological greenery in the four major metropolitan areas of the Yangtze River Delta. Financial agglomeration can have a positive local and neighborhood impact on the coordinated development of ecological green, and this varies by metropolitan area. Information transfer and technical correlation are important intermediate mechanisms. Different agglomerations of nancial institutions and personnel have different "green potential energy" effects.Shanghai has the greatest radiation effect, Nanjing has a "U" type effect, Hangzhou has an inverted "U" type effect, and Hefei has no effect.

Based on the panel data of a total of 25 prefecture-level cities in the four major metropolitan areas in China’s Yangtze River Delta region from 2003 to 2019, the Dubin model of three types of spatial weight matrix is used to compare and explore the impact effect and mechanism of financial agglomeration on the coordinated development of ecological green.
