Measurement Method of Digital Economy Scale in China

The rapid transition to “digital economy” is the result of a series of innovations. Computers have witnessed the development of semiconductor transistors, integrated circuits, personal computers, operating systems and graphical interfaces. With the emergence of optical fiber and new wireless communication technology, the physical layer of telecommunication has been realized, and the network has witnessed the development of Internet (basically packet switching) and World Wide Web. Together, these advances have led to a range of new ICT applications, such as business software, e-mail and e-commerce. This paper uses P-Star model to improve it, calculates the empirical equation, forecasts the inflation pressure measurement, and compares it with the actual situation. Firstly, the weight of land narcotization is revised annually, and the number of cases based on dynamic coefficient and the scale measurement method based on dynamic coefficient are proposed. Using the method of econometrics, it provides theoretical reference for the application of the theory. The results show that: the development level of China's manufacturing industry increases with the year, and the highest proportion of manufacturing industry is 34% in 2020.
