Under the new development pattern，the integrated development of the digital economy and the cultural industry in metropolitan agglomeration has become the trend of the times in promoting the high-quality development of the cultural industry. Relying on the theory of industrial integration，the article deeply explains the theoretical logic of the integrated development of the digital economy and the cultural industry of metropolitan agglomerations，through the systematic analysis of the integrated development effects of the digital economy and the cultural industry of metropolitan agglomerations，three types of integrated development models of the digital economy and the cultural industry of metropolitan agglomeration are extracted，including digital+ content-led，digital+ service-led，and digital+consumption-led. This paper puts forward the basic path to realize the three types of integrated development models，and provides theoretical and practical references for the differentiated development of cultural industries in metropolitan agglomerations and the realization of regional high-quality integrated development.
