Abstract: In recent years, with the continuous deepening of the digital economy in China and the development of digital applications due to COVID-19 situation, digital transformation has been raised to the top priority for enterprise survival and development. But many enterprises, specifically those engineering design companies whose information level is weak, cannot clearly understand what digital transformation is, how change can be made, and what the relationship between the digital transformation and information digitalization is. Based on the above concerning, the author hopes to help readers return to the essence, to clarify thoughts, to understand the underlying logic and value demand of the digital transformation, and to explore the road of digital transformation of engineering design enterprises with the concept of "long-termism, value symbiosis".
