Abstract: China's regional GDP inequality showed a downward and then an upward trend in 1949—2019, and it also showed a similar trend in the past decade Regional per capita GDP inequality is in a state of horizontal fluctuation, and appears σ convergence in recent years and β convergence in 2019 At present, weak innovation ability, high government debt ratio and low proportion of labor are important reasons for lack of driving force in less developed areas R&D expenditure, capital stock and employment scale are the main reasons for the formation of regional economic inequality, which can explain 889% of provincial level GDP difference and 591% of per capita GDP difference from 1999 to 2019 R&D expenditure and employment scale are the main causes of regional GDP inequality, and R&D expenditure and capital stock are the main causes of regional per capita GDP inequality The spatial econometric analysis shows that the spatial spillover effect of China's regional economic growth is significant, but the spatial spillover effects of R&D expenditure, capital stock and employment scale are different Only R&D expenditure has positive spatial spillover effect on economic growth, and there are certain differences in the spatial spillover effects of the three economic belts in the East, the West and the middle region
