Research on Health Evaluation of Sustainable Regional Innovation Ecosystems Based on Improved Niche Suitability Model

While researchers have used the traditional index system -part of the niche-fitness model -to evaluate the innovation ecosystem, this index system can be seen as not being sufficiently objective, with the consequent problem that it gives equal weight to the indicators and so does not specify the important factors. To remedy this problem of insufficient objectivity, this paper seeks to improve the traditional niche-fitness model in two ways, which are based on the theory of the innovation ecosystem. First, by introducing the principal components analytic method to solve multiple mutual linear problems. Second, by constructing a new evaluation index system from the four aspects of openness, synergy, sustainability, and growth. This new evaluation index system is closer to the characteristics of the organic and evolutionary nature of the sustainable innovation ecosystem compared with the traditional index system.
