Urban agglomeration is the main space for structural adjustment and high-quality development of the man-ufacturing industry.Based on the 2011-2021 data of the three major urban agglomerations of Beijing-Tianjin-Hebei,Yan-gtze River Delta and Guangdong-Hong Kong-Macao Greater Bay Area,this paper uses a combination of theory and empirical methods to explore the impact of the digital economy on the up-grading of the industrial structure of the manufacturing industry in the three major urban agglomerations from the city level.The research finds that the digital economy has a significant impact on the upgrading of the manufacturing industry structure in the three major urban agglomerations.Compared with the three ma-jor urban agglomerations,the impact of digital economy on the upgrading of manufacturing industrial structure in Beijing-Tian-jin-Hebei and Yangtze River Delta urban agglomerations is greater than its rationalization impact,while the Greater Bay Ar-ea urban agglomerations are the opposite.The digital economy has a nonlinear influence on the upgrading of the manufacturing industry structure in the three major urban agglomerations.La-bor skill structure is the mechanism factor that digital economy promotes the upgrading of manufacturing industry structure.There are differences in the degree of impact of the three major urban agglomerations on the upgrading of the industrial structure of the manufacturing industry in the dimensions of digital infra-structure level,digital application level,digital industrialization level and digital development environment.Therefore,all locali-ties should base on their own characteristics and advantages,im-prove the internal coordination and communication mechanism of urban agglomerations,strengthen the upstream and downstream coordination of the manufacturing industry chain,improve the digital technology personnel training system,and promote the digital economy to enable the high-quality development of man-ufacturing.
