Abstract: Promoting the digital transformation of traditional enterprises is conducive to the deepening development and the sustained prosperity of digital economy. This paper argues that the technological paradigms of digital transformation mainly include industrial Internet, smart manufacturing, etc., but these paradigms are generally visionary, and there are still great deficiencies to support the practice of digital transformation at the level of firm. The key point of digital transformation lies in practice and problem-orientation, strengthening the application of digital technology in traditional enterprises, constantly improving the level of enterprise digitalization, and promoting the development of industrial digitalization. At the industrial level, it is necessary to strengthen trans-regional and cross-industry digital infrastructure and strengthen key technology support; At the enterprise level, it is necessary to explore the evolution path of "digital-ecology-synergy", and establish the transformation roadmap from point to area. Finally, managerial implications for digital transformation of traditional enterprises are discussed.
