Abstract: Based on China忆s provincial panel data from 2011 to 2019, the entropy method is used to synthesize comprehensive indicators of regional financial risks, to empirically test the impact of financial agglomeration on regional financial risks, and to analyze the mechanism of financial agglomeration on regional financial risks by using an intermediary effect model. The results show that: from a national perspective, financial gatherings intensify the formation of regional financial risks; from the perspective of regional regression, as the level of financial agglomeration increases, the effect of aggravating regional financial risks gradually decreases; as the level of financial agglomeration in the western, central and eastern regions increases, the effect of aggravating regional financial risks gradually decreases; among them, in the eastern region, high levels of agglomeration will have a restraining effect on regional financial risks; further research found that technological innovation has an intermediary effect of 22.35% in
the process of financial agglomeration忆s impact on regional financial risks.
