Firstly,the evaluation index system of common prosperity is constructed based on the four dimensions of process,wealth,sharing and sustainability.Secondly,the entropy-TOPSIS method is applied to measure the common prosperity level of 30 provinces in China from 2005 to 2020.Finally,the kernel density estimation is used to analyze the spatiotemporal evolution trend of common prosperity level,the Dagum Gini coefficient applied to decompose the regional differences,the obstacle factor diagnos-tic model adopted to explore the obstacle factors of common prosperity.The findings go as the following:During the sample period,the common wealth level of China's provinces shows an increasing trend,and there exist a typical gradient difference.The pros-perity level is higher than the level of sharing,process and sustainability.The overall common prosperity level shows a layout of"high in the east and low in the west,high in the south and low in the north".The internal evolution trend of eastern,central and western regions is heterogeneous,and the inter-regional differences are the main source of overall differences.The main influenc-ing factors of common prosperity come from innovation-driven fields.
