In the era of vigorous development of the digital economy，digitalization has profoundly affected the evolution of steel industry policies in many countries around the world. Based on the sorting out of the development process of global industrial digitalization，this paper finds that in the budding stage，forming stage and deepening stage of industrial digitalization，the world’s major countries gradually form information infrastructure and digital technology to enable industries to improve quality and efficiency，and industrial Internet to rebuild new industries in digital development. Modes，industrial platform development ecology and industrial clusters boosting industrial digital development and other phasedcharacteristics，the research perspective gradually focuses on the digital development of the steel industry. Based on the analysis of the digitalization policies of the iron and steel industry in different countries in different periods，it can be concluded that the digitalization policy of the iron and steel industry has an effect on the digital development of the iron and steel industry through three paths：innovating the production management technology of the iron and steel industry，building an intelligent iron and steel industry chain，and improving the construction of the iron and steel digital infrastructure. In order to promote the digital and intelligent development of the iron and steel industry，the government should accelerate the upgrading of digital technology in the iron and steel industry and improve the competitiveness of iron and steel products；build an industrial chain of iron and steel intelligent manufacturing，and promote the upgrading of the iron and steel industry structure；coordinate the construction of digital infrastructure and promote the rational distribution of the iron and steel industry. Further play the guiding and supporting role of the digitalization policy of the steel industry.
