A complete index system was constructed to measure the high-quality economic development level of 30 provinces and regions in China by entropy weight TOPSIS method,and the Dagum Gini coefficient was used to ana-lyze the differences among the four regions,and the fsQCA method was used to analyze the combined effects of dif-ferent dimensions in the index system and how to promote the organic combination of these indicators.The results show that the level of high-quality development of national economy is on the rise;The central and eastern regions performed best,followed by the central,northeast and western regions.The difference of high-quality economic de-velopment mainly comes from the difference between regions,which shows a downward trend on the whole,among which the difference between the east and the west,the east and the central has a large decline.In this way,we should strengthen the cooperation and exchange between provinces and narrow the differences between regions.We will adapt to local conditions,give full play to the strengths of provinces and regions,and promote the integrated development of urban clusters.
