Manufacturing intermediate goods play a powerful role in stabilizing and fixing industry chain and stands as the mainstay in establishing the dual-circulation development pattern.Based on the input-output model,this paper constructs a framework for decomposing the dual circulation of intermediate products input and usage,measures the foreign-related circulation of China's manufacturing intermediate products,and makes an international comparison.The research finds that the scale and growth rate of foreign-related circulation on intermediate products in China's manufacturing industry are ahead of the United States,Japan,and Germany,but the proportion is smaller than that of the United States,Japan,and Germany.Judging from the degree of foreign-related circulation,the higher the level of technology,the larger is the scale and proportion of foreign-related circulation involving intermediate products,with medium and high-tech manufacturing sectors showing a strong dependency on international markets for intermediate inputs.On the demand side,China's manufacturing industry is mainly involved in foreign transactions at the final goods stage,whereas the United States,Japan,and Germany primarily engage in foreign trade at the intermediate goods stage.Moreover,the dependency of China's overall and medium to high-tech manufacturing sectors on foreign-related production networks is lower than that of the US,Japan,and Germany,while reliance on foreign final demand markets is higher than that of the US but lower than Japan and Germany.This paper expands the dual circulation decomposition model,providing a useful reference for exploring the evolution of China's manufacturing intermediate products foreign-related circulation,and expanding manufacturing intermediate products trade.
