Research On The Evolutionary Characteristics And Adaptability Improvement Of An Innovation Ecosystem Based On The Perspective Of Core Member

As a relatively new research field in the field of innovation management,the innovation ecosystem plays a key role in the development of innovation activities.What's more,the evolution problem is an important fundamental issue of the innovation ecosystem,and the interaction mechanism between members is one way to further clarify the system development.While at present,the research on the evolution of innovation ecosystems seldom reflects the characteristics of mutual benefit and symbiosis among members,also not embody the dynamic optimization process of the innovation ecosystems.Furthermore,the research on member interactions less considers the role of core members.Based on this,we explore the general system characteristics and the interaction characteristics among members in process of the evolution of innovation ecosystem through simulation,in order to find out their different influence on the innovation ecosystem.Based on the different members and the different relationship strength among various members will produce different influence on the adaptability of innovation ecosystems,so this paper firstly expand the basic NK model by introducing weight parameter and relationship strength,and then research the evolution path based on the expanded NK model.The results show: ?1 Based on the perspective,compared to the traditional view to “Fill short board”,“Fill long board” will achieve higher efficiency;?2 Suitable relationship strength will improve the adaptability of innovation ecosystems;?3 Globle vision helps to choose the optimal evolution path of innovation ecosystems.Secondly,based on the expansion of the NK model,by adjusting the system scale,the number of interactions between members and the intensity of interaction,the interaction mechanism of the innovation ecosystem and its impact on system fitness are analyzed.The results show that,when other factors remain fixed,considering the role of core members,the size of the system and the changes in the number of interactions between other members will have an apparent impact on system fitness,and the trend of change can be expressed by a clearly fluctuating line.
