Service innovation is the driving force of social progress and provides necessary impetus to the overall economic growth of the service industry. Although the importance of service innovation is very strong, the current definition of related concepts and definitions in academia is not yet clear. A large-scale economy as a whole can be interpreted as a large service system that contains a variety of interrelated subsystems. Therefore, to further promote the economic development through service innovation, we need to know how to establish the management mechanism of service innovation at the enterprise level. This paper gives a new definition of service innovation and also points out the difference between the traditional model of innovation and new models of innovation. This paper pays special attention to the promotion of enterprise services, and relies on relevant theories of management to construct a service innovation management mechanism for enterprise service innovation based on theoretical guidance.
