This report analyzes the indicators of 30 provinces in China from 1990 to 2022 in terms of index，classification and ranking. The indicators here are composed of five first-class indicators：economic growth，growth potential，government efficiency，people’s life and environmental quality. The report also assesses its development prospects during the 14th Five-Year Plan period. According to the report，China’s economy is facing a structural slowdown；however，under the severe impact of the epidemic that has lasted for nearly three years，the development prospects and the quality of economic development of China’s provinces，autonomous regions and cities have still been stabilized，restored and improved to a certain extent. In terms of development prospects，economic growth and people’s lives，the improvement in the western region is better than that in the eastern region and the central region. And the improvement in environmental quality in the central region is better than that in the eastern and Western Regions And the improvement in economic growth，growth potential，government efficiency and environmental quality in the eastern region is better than that in the central and Western Regions. From the comparison of regional development stages during the epidemic period，in terms of regional development improvement index，except for environmental quality，the improvement in the western region is better than that in the eastern and central regions. The quality of economic development in developed regions has been more seriously affected than that in developing regions，resulting in a certain reduction in regional differences. However，this is not what common prosperity hopes to achieve，but because developed regions are facing a more serious setback than the central and western regions. At the same time，with the deepening development of urbanization，the requirements of public services，social security，quality of life and ecological environment have gradually risen to a more important position.
