Abstract: According to the development thought of the Communist Party of China on common prosperity and the summary of Xi Jinping’s important exposition on common prosperity, common prosperity can be embodied in four sub-dimensions: development adequacy, development balance, fairness and sharing. Through further analysis of the four sub-dimensions, we can construct an index system of common prosperity that conforms to China’s characteristics, and conduct a concrete measurement and analysis of the common prosperity index concretely. The measurement results of national level data from 1992 to 2021 show that the national common prosperity index has been increasing since 1992, at a low level from 1992 to 2001, and accelerated after 2002. The changes of the four sub-dimensions of common prosperity are quite different. The development adequacy and sharing level are greatly improved, the development balance presents a inverted U-shaped tendency, and the fairness growth is tortuous and overall slow. However, the coupling and coordination of the four sub-dimensions of common prosperity are constantly improving, which means that the four sub-dimensions tend to develop synergistically. The measurement results of provincial data from 2012 to 2021 show that the regional heterogeneity of common prosperity development is significant; the common prosperity index in the eastern region is higher than that in other regions, which plays a leading role, while the common prosperity index in the central and western regions has great room for growth. The above conclusions show that to further promote the realization of common prosperity, it is necessary to pay more attention to the balanced development and fairness, and maintain the promotion of sharing and ensure the sustainable growth of development adequacy.

Key words: common prosperity, development sufficiency, balanced development, fairness, sharing
