Concept Refinement and Redefinition of Innovation

摘要

This article starts with an analysis of the concept of innovation, and argues that at the core of the concept is value realization. Secondly, it analyzes the technology-driven linear innovation model, de-mand-pull linear innovation model, synchronouscoupled model, interactive model, network model chain and the dynamic interactive innovation model. Finally, this article proposes the ecosystem of innovation, on the bases of analyzing innovation system theories. Innovation is an extremely powerful, dynamic interaction sys-tem, and there is great uncertainty in the system.
