A new round of scientific and technological revolution is booming, and new technologies such as big data, artificial intelligence, and block-chain promote comprehensive innovation in the economy and society. The digitization process in various industries and fields is accelerating, and the accounting industry is also deeply affected. The cultivation of intelligent compound accounting talents is imminent, and universities play a vital role in talent training. Based on the application-oriented undergraduate colleges and universities, based on the era of digital economy, the 1+X certificate system and the background of school-enterprise cooperation, this study takes the mixed teaching of big data financial analysis based on the DEEP platform as an example to explore the transformation from traditional accounting talents to intelligent compound accounting talents. The new path of training promotes the integration of production and education, and provides reference for the training program, curriculum, and teaching of accounting talents in colleges and universities.
