Abstract:From the linear innovation development to the innovation system and then to the innovation ecosystem which is now highly valued, various fields have carried out rich research. Through sorting out the concept of innovative ecosystem, We found that the understanding of concepts in the academic circle so far has not reached a consensus due to the differences in subject sources and theoretical perspectives. Aiming at this problem, this paper puts forward that the root of the difference is the heterogeneity and diversity of the system subject, the fuzzy and fluidity of the boundary, and further summarize the optimization progress of the concept. Finally, this paper put forward on this basis that Innovation ecosystem is a dynamic network system that can co-exist and co-exist through collaborative innovation between innovation organizations with enterprise as the core and between innovation organizations and innovation environment, and emphasizes two innovative points: "limited metaphor" and the emphasis on "users".
