Based on the Super-SBM variable model of non-radial returns to scale,this paper measures the provincial public service supply efficiency from 2003 to 2020,and uses Dagum Gini coefficient and its decomposition method to measure the re-gional differences and contribution sources of public service supply efficiency,and then uses mixed regression to test its β con-vergence characteristics.The results go as below:(1)The efficiency of public service supply in China shows an obvious gradient characteristic of"high in the east and low in the west".(2)The difference of public service supply efficiency mainly comes from the difference between regions,followed by the difference within regions,and the difference contribution caused by intensity of transvariation is the smallest.Specifically,the inter-regional differences in the efficiency of public service supply show certain cyclical fluctuations,while the intra-regional difference contribution and intensity of transvariation contribution remain low.(3)The efficiency of public service supply in the country as a whole and in the eastern,central,western and northeastern regions shows obvious absolute β convergence and conditional β convergence.
