Abstract: The current green industrial Internet system has many problems in energy efficiency, privacy, resource management, etc., and more technologies from different fields need to be integrated to realize the development of green industrial Internet. The current research and implementation technologies were summarized, and an outlook on the development and challenges of green industrial Internet was provided. First, the basic architecture and technical characteristics of industrial Internet were introduced, and the realization path of "greening" industrial Internet was discussed from multiple perspectives around the frontier network technologies, such as green communication, mobile edge computing, blockchain, etc. Second, the development status of green industrial Internet and the key technologies involved in the construction of actual scenarios were summarized in detail. Finally, in view of the problems and challenges faced in the development of green industrial Internet at this stage, the solutions and development trends of building a green industrial Internet system were discussed.
