From the perspective of final demand, this paper uses the inter-provincial non-competitive inputoutput tables in China in 2012 and 2017, expands the traditional accounting method, and divides the national economic cycle into “domestic and local the four links of domestic and inter-provincial circulation”, “domestic and international circulation” and “international circulation” measure the degree of domestic and international circulation, and discuss the basic characteristics of China’s participation in domestic and international circulation. The main research findings are: (1) At the regional level, different regions in China showed the strongest degree of “domestic local circulation” in 2012 and 2017. Compared with 2012, the degree of “domestic local circulation” in China in 2017 increased, The degree of “international circulation” has decreased, but this does not mean that a new development pattern has been formed; (2) At the provincial level, the degree of participation in dual circulation in different provinces in China is signifi cantly different, and the degree of “domestic local circulation” is relatively different in different provinces. The highest degree of “international circulation” is relatively low. Provinces with a high degree of “domestic local circulation” are mainly concentrated in the central and western regions; (3) At the sectoral level, consistent with the research results at the regional and provincial levels, different industry sectors still use the “domestic local circulation”. Most of the technology-intensive and labor-intensive industries participate in the “international cycle” relatively deeply. Therefore, China should continue to strengthen the development pattern with the domestic cycle as the main body, and the key is to open up the pain points and blocking points of the domestic market, focus on expanding the domestic market demand, and take advantages of China’s super-large domestic market.
