Economic growth convergence is an impor-tant condition for coordinating regional development and promo-ting common prosperity.This article is based on the framework of economic growth convergence analysis,and uses panel data from 267 prefecture level cities in China from 2011 to 2020 to explore the impact and mechanism of digital economy on regional economic growth convergence in China.Research has found that the digital economy can significantly promote urban economic growth in China and accelerate the convergence of regional eco-nomic growth,narrowing the economic development gap between regions.Mechanism analysis shows that the digital economy can promote economic growth in underdeveloped areas by improving their innovation and development capabilities,as well as impro-ving the mismatch of capital factors,and assist in coordinated regional development.At the same time,the digital economy ex-hibits significant geographical and fiscal differences in promoting regional economic convergence,significantly promoting economic growth convergence in western,northern,non coastal cities,and cities with low fiscal self-sufficiency rates.It is recommended to continue strengthening digital infrastructure,accelerating the construction of digital cities,vigorously developing the digital e-conomy,and assisting in the construction of a unified national market through regional cooperation.
