Life cycle identification of China's regional innovation systems based on entropy weight disturbing attribute model

Regional innovation systems (RISs) characterized periodical and is suitable for analyzing the Chinese economy which has entered the new normal. However, few scholars analyze and identify the stage of RISs from the perspective of life cycle. This paper divides the life cycle of RISs into four stages: initial stage, growth stage, maturity stage, and decline stage. Based on the analysis of the characteristics in every stage of the life cycle in the RISs, this paper constructs entropy weight disturbing attribute model to identify the stage of 31 provincial innovation systems in China. The research results show that all the RISs in maturity stage belong to the eastern developed regions, and innovation achievement capacity is significant. The RISs are widely distributed which are in the growth stage. The innovation efficiency capacity, innovation growth capacity and innovation network capacity of RISs which are in growth stage are in a high level. The provinces with the innovation system in the initial stage are mainly in the backward areas of the west, and the innovation growth capacity is better than other innovation capacities. Mastering the evolutionary stage of the RISs is helpful to promote the implementation of innovation-driven development strategies.
