Abstract: Based on the network analysis method, this paper comprehensively uses the world input-output tables compiled by the European Union and the Asian Development Bank to dynamically compare the domestic industrial circulation between China and the United States. The results show that the total volume and proportion of domestic circulation in China have increased, while the total volume in the United States has not changed significantly, the proportion has decreased to some extent, and the performance of manufacturing reshoring is not obvious. From the perspective of the input-output network, the US has relatively balanced domestic industrial linkages, and the distribution of industrial linkages has not changed much, while China?s domestic linkages are relatively unbalanced and industrial linkages have gradually increased. The industrial community in China presents the phenomenon of clustering in the same industry such as manufacturing and services, while the industrial community in the US is relatively even. In terms of core sectors, China is led by construction and manufacturing industries, while the US is dominated by public service industries and service industries. According to the strongest industrial chain selection, China’s selected industrial chains focus on manufacturing led by construction, including some services, while US’s is predominantly services led by public services.
