With the continuous application of various digital technologies in traditional manufacturing，the digital economy has become an important driving force for promoting the transformation and upgrading of traditional manufacturing. At present，the process of digital transformation of China’s manufacturing industry has been further accelerated. Industrial Internet has promoted the key infrastructure for the transformation and upgrading of the manufacturing industry. Although the digital transformation and upgrading of China’s manufacturing industry has achieved remarkable results，it still faces many challenges. Digital infrastructure is still difficult to support the transformation and upgrading of traditional manufacturing industry. The degree of digital integration and development of the manufacturing industry is still relatively low，and the degree of cooperation of the digital enabled manufacturing industry chain is not high. To address these challenges，it is necessary to further promote the construction of digital infrastructure，improve the degree of industry chain collaboration empowered by digitization，and cultivate digital technology talents.
