Evolutionary Characteristics and the Adaptability Improvement of an Innovation Ecosystem Based on an Extension NK Model

Based on the influence of members’ roles and their relationship strengths on the adaptability of an innovation ecosystem, this paper extends the basic NK model by introducing weight parameter and relationship strength parameter. According to the extended model, three evolutionary characteristics are obtained. Firstly, for an innovation ecosystem, compared with the traditional view of “strengthening the weakness”, “strengthening the strengths” will achieve a higher efficiency for its adaptability enhancement. Secondly, a suitable relationship strength but not a highest one will help to enhance its adaptability. Finally, a global vision will help to achieve the optimal evolution path. Moreover, on the basis of the evolutionary characteristics, we put forward three strategies to improve the system adaptability.
