摘要Comparisons of the economic structures between China and Japan have consistently intrigued development economists. In order to explore the sectoral distinctions between these two nations from 1995 to 2018, we analyzed the annual input-output tables (IOTs) to construct weighted and directed input-output networks (IONs). This approach allowed for more nuanced network analyses. Variations in strength distributions highlighted differences in economic interactions across sectors. The weighted, directed assortativity coefficients illustrated the tendency of similar sectors to connect. Adjustments in PageRank centrality helped pinpoint the key sectors, while community detection techniques shed light on the clustering patterns within the sectors. As expected, the analysis identified manufacturing as the pivotal sector in China, whereas Japan leaned towards the services sector. However, upon closer examination, each country showed distinct sectoral developments. Despite these differences, the sectoral communities in both China and Japan displayed remarkable stability throughout the period studied.
