The industrial ecology of 5G applications is an important manifestation of the scale, systematization and industrialization of 5G applications. It is also a co-creation mode that can improve the resilience, security and stability of the 5G application industry, optimize the development mode of the 5G application industry, and promote the prosperity and symbiosis of the 5G application industry in collaboration with all resources can be called the 5G application industry ecology. The current situation of the ecological development of 5G application industry was summarized, the problems and obstacles encountered in the current development process were systematically analyzed, universal solutions were innovatively designed. Scientific, targeted and developmental policy suggestions in combination with the development trend are put forward, with a view to further strengthening, improving, doing a good job in the ecological development of 5G application industry, consolidating the foundation of 6G application development, and building the ecological development of 5G application industry into an important hub and core driving force for the new industrialization development in our country.
