In the era of digital economy，the industrial Internet has become the key support for the digital transformation of manufacturing industry. Inrecent years，Henan Province has continued to promote the development of industrial Internet，and has made certain achievements in the construction of platform system，the cultivation of key platforms，and the construction of secondary nodes of the industrial Internet identity analysis. However，the development of industrial Internet in the whole province is still at the initial stage of exploration，facing such constraints as insufficient supply capacity of industrial Internet，insufficient large-scale application of small and medium-sized enterprises，and insufficient talent reserve. We should fully release the development potential of the industrial Internet and accelerate the digital transformation process of Henan’s manufacturing industry by improving top-level design，deepening integrated application，strengthening platform introduction and training，and improving the security system.
