Abstract: Based on the input-output sequence tables, this paper proposes a theoretical framework of factor accounting of digital economy, and carries out the actual measurement and application analysis on the digital economy factor structure of China. The results show that the digital capital service volume reached 6820.896 billion yuan in 2018, accounting for about 13.28% of the total social capital service volume in the whole economy. During 2002—2018, the average annual growth rate of digital capital services is 20.37%, in which the average annual growth rate of digital hardware capital services is 13.65%, and the average annual growth rate of digital software capital services is 27.21%. Obviously, the role of digital software capital services in promoting the growth of total capital services is more and more important. A further study finds that the digital software factor can significantly improve industrial output, while the influence of digital hardware factor on the development of industrial sectors decreases. Improving the labor structure can significantly increase the actual labor input of the whole society and promote industrial development. Therefore, China should give full play to its advantages as a digital economy giant, improve the governance capacity of the digital economy, and promote digital integration of traditional industries, to fulfill high-quality economic development.
