Abstract: At present, the digital economy has become the core force leading the technological revolution and industrial transformation. However, there is no unified definition of the digital economy and industrial classification standards in the world. It is urgent to clarify the statistical definition of the digital economy and unify industrial classification standards to provide support for further research and analysis. First of all, this article systematically sorts out the narrow and broad definitions of the digital economy and then defines the digital economy in a broad sense. Secondly, this article summarizes its production activities as two parts: core activities and application activities. Finally, in the construction of China ’ s digital economy industrial classification, the core activities of the digital economy are identified as 4 major categories ( digital equipment manufacturing, digital product trade, digital technology services, and digital-driven industries) and 19 medium categories; the application activities of the digital economy are identified as 5 major categories ( e-commerce industry, digital content industry, digital financial industry, digital government industry, and other digital industries) and 24 medium categories; a total of 9 major categories and 43 medium categories. The research results of this article provide basic support for the improvement of China ’ s digital economy industrial classification standards, industrial policy formulation, and quantitative measurement of the industry.
