At present，the world’s century changing situation and century epidemic situation are intertwined and superimposed. A new round of scientific and technological revolution and industrial reform represented by digital technology are developing rapidly. In order to meet the challenges，various countries have implemented advanced manufacturing plans with the new generation of network information technology as the core driving force，in order to seize the commanding height in the future development. Machinery industry is the main body of equipment manufacturing industry and the basic and strategic industry of national economic development and national defense construction. Its digital development has become a “necessary topic”. This paper elaborates the background of the sluggish world economic growth，the acceleration of industrial transformation by the scientific and technological revolution，and the development of the machinery industry facing multiple pain points and difficulties，discusses the development status and level of the continuous consolidation of infrastructure construction，the accelerated integration of the industrial chain supply chain，the wide application of industrial software，and the accelerated pace of service-oriented manufacturing in the digital transformation and development of China’s machinery industry，and further proposes to strengthen the independent innovation of enterprises，the coordinated operation of the chain，the optimization of the industrial structure，the convergence of multiple resources，and international exchanges and cooperation，in an all-round，multi-level，A wide field perspective accelerates the digital transformation of China’s machinery industry.
