In recent years，Henan Province has made some progress in promoting the digital transformation of manufacturing industry by taking the integration of industrialization and informatization as the main line，intelligent manufacturing as the main direction and increasing policy support. It should be noted that there are both favorable and constraint factors in the digital transformation of Henan manufacturing industry. At present，the digital transformation of manufacturing industry should focus on R & D mode，manufacturing mode，organizational form，product form，business mode，etc. and we should know the content and direction of transformation；to give full play to the leading role of enterprises，on the other hand，we should pay attention to the overall improvement of the industry，rely on the strong support of the government. We will accelerate the transformation and upgrading of traditional manufacturing industry through the support of enterprises and the coordinated promotion of the government.
