Abstracts: Common wealth and digital economy are two important issues in China's develop‐ ment today. Entering the new development stage, exploring how to reconcile the digital economy  and common wealth is of great theoretical and practical significance. Theoretically, digital  economy can empower and promote common wealth, and common wealth also opens up new de‐ velopment space for digital economy. Based on the provincial panel data from 2011 to 2021, this  paper makes a comprehensive evaluation of the development level of China's digital economy  and common wealth, analyses the coupling and coordination relationship between the two  through the coupling and coordination model, and explores the problems faced by the two in coor‐ dination. Specifically, based on relevant theories, this paper firstly constructs the index system of  digital economy and common wealth, and examines in detail the evolution trend and regional dif‐ ferences between digital economy and common wealth in provinces of China. Secondly, use the  coupling coordination degree model to measure the coupling coordination degree of digital  economy and common wealth in provinces and cities in China. The coupling and coordination re‐ lationship between the two is specifically to analyze the coupling and coordination dynamics of  the two from the level of first-level indicators. At the same time, according to the level of eco nomic development ‐ , the country is divided into eastern, central, western and northeastern re‐ gions, and the coupling and coordination relationship between the two is discussed by region, so  as to observe the different performances of the coupling and coordination relationship between  digital economy and common wealth in each region. The results of the study show that:①China's digital economy composite index and common  wealth composite index have both increased significantly from 2012 to 2021, both of which show obvious regional differences, with the eastern region's development level leading the other re‐ gions. ② The coupling and coordination relationship between China's inter-provincial digital  economy and common wealth shows an increasing trend, but there are still uncoordinated factors, the development of inter-regional imbalance, and the coupling and coordination relationship be‐ tween the two is especially obvious in the eastern region.③From the analysis of the coupling and  coordination of digital economy's primary indicators and common wealth, there are significant re‐ gional differences in the development foundation of China's digital economy and the coupling de‐ gree of common wealth; the coupling relationship between digital industrialization and common  wealth is vulnerable to external factors; the level of the coupling and coordination relationship  between industrial digitization and common wealth is relatively high, and the gap among the re‐ gions is relatively small.④From the analysis of the coupling and coordination of digital economy  and common wealth's primary indicators, the coupling relationship between digital economy and  affluence is stronger. There is overall coordination between digital economy and sharing degree, but some provinces are in a dysfunctional state Based on the findings of this paper, . it is recommended to construct specific paths to pro‐ mote the coordinated development of digital economy and common wealth in terms of promoting  the overall digital transformation, narrowing the gap of digital economy among regions, adjusting  and optimizing income disparity and the structure of income distribution, and upgrading the  level of western regions' development.
