Abstract: As a new engine of high-quality development of China′s economy, the digital economy plays an important role in promoting economic growth and transforming people′s lifestyles. However, the statistical accounting of the digital economy lags significantly behind its growth, which is not conducive to monitoring the development of digital economy and the formulating scientific policies by relevant departments. This paper reviews the conceptual evolution and the statistical classification of digital economy from OECD、 US BEA and official statistical department. Combined with the relevant statistical classification standards in China, the statistical classification of China′ s digital economy industries is proposed, including 5 categories-digital equipment manufacturing, digital information transmission, digital technology services, digital content and media, Internet application and related services-a total of 22 subcategories and 122 groups. A comparative analysis of with the industrial classification of digital economy from OECD and US BEA is also done.
