Digital economy is a new form of economic and social development after agricultural economy and industrial economy, and it is becoming a new momentum of global economic development. Therefore, it is of great significance to study the digital economy. Based on the digital economy indices of China's 31 provinces and 351 cities published by the"Internet plus"digital economy index platform of Tencent Research Institute,this article analyzes the spatial differentiation characteristics of Chinese digital economy and its foundation, industry, innovation and entrepreneurship, and the wisdom of the people's livelihood in 2016 by using the methods of interpolation simulation and rank-size rule, and then we use correlation analysis and geographical detector model to detect and compare the influencing factors of digital economic development in China and its inner regions. The main conclusions are as follows. 1) The spatial differentiation of Chinese digital economic development is obvious. The development level of digital economy and its four dimensions is decreasing from east to west at the provincial level, at the same time, there are new poles of innovation and development in Sichuan,Chongqing and so on. At the urban scale, national urban agglomeration area is the absolute height of the development of digital economy, such as Beijing-Tianjin-Hebei Urban Agglomeration, the Yangtze River Delta Urban Agglomeration, the Pearl River Delta Urban Agglomeration. 2) There are both coordinated development and differentiation among the various dimensions of the digital economy, and the differences between the four plates of the East, Middle, West and Northeast China and their interior are obvious, especially between the eastern region and the other three regions. 3) The dominant factors influencing the development of digital economy at different spatial scales are different. At the national level, the government's commitment to science and technology plays an important role. However, the factors influencing the development of the digital economy in the eastern region are quited, and all the factors are independent. And the influence of informatization foundation and potential factors plays a leading role in the development of digital economy in Central China, and the interaction force of each factor is obviously strengthened. However, there is no decisive factor in the western region, which is affected by many factors. The factors influencing the development of digital economy in Northeast China are relatively single. Through the analysis of research conclusions, we can find that the development of digital economy has provided new opportunities and challenges for areas with weak economic foundation, it is expected to drive the national economy through the digital economic development and realize"overtaking by turns".
