In this study, we empirically analyze the impact of the effects of digital inclusive finance (DIF) on high-quality economic development in Chinese prefecture-level cities. We find the following conclusions: first, the total index and sub-index of DIF can promote high-quality economic development. Second, DIF significantly promotes high-quality economic development by narrowing the urban-rural income gap and alleviating financing constraints. Third, DIF is conducive to the improvement of economic quality in neighboring regions.
