Abstract: About whether there is convergence in regional economic growth，the existing empirical literature largely ignores the spatial heterogeneity of the convergence rateBased on the neoclassical economic growth theory，the article constructs a spatial Durbin panel quantile model and examines the spatial heterogeneity of economic growth convergence in 336 prefecture-level cities in ChinaResults show that the economic growth of various cities in China is generally converging，and the rate of convergence is U-shaped as the quantile increasesConsidering the free flow of capital among regions，the role of savings rate in low-growth and medium-growth regions is significantly reducedHigh-growth regions are less driven by the surrounding economies than in low-growth and medium-growth regions，so the rate of convergence in high-growth regions has become greaterFurther analysis finds that the southern and northern regions，and the eastern and western regions all exhibit the characteristics of club convergence，while the economic growth of the central region is characterized by economic divergence in high-growth regions and convergence in low-growth regionsIdentifying the spatial heterogeneity of regional economic growth is very important for the government to better implement regional coordinated development strategies to reduce regional economic differences
