Abstract: With the intensification of competition in the electric commercial vehicle market and the diversification of user demands, traditional manufacturing models have been facing challenges such as long research and development cycles, high production costs, and low quality consistency. The study systematically analyzes the application logic of digital technology in research and development, production, and supply chain links, proposes a new production and manufacturing model based on intelligent decision-making, and constructs a three in one implementation path of technology organization ecology. The research has shown that the digital technology driven, the full process cost has been reduced by 15%~30%, and the iteration speed of research and development products has been increased by more than 50% of electric commercial vehicles, and promote the industry's transformation towards flexibility and lean; The study provides useful reference for the upgrading and transformation of digitalization and intelligence of electric commercial vehicles.
