Conclusion

In the innovation ecosystem，the adjacent region enterprise innovation population affects each other.Within a region，there is complex interactive behavior within the innovation population.This interaction can be either collaborative or competitive.The innovation ecosystem can carry on the self organization evolution，and the cooperation among different regional population and the enterprise within a certain area can promote the win-win situation of many groups.Enterprise innovation groups in different regions compete for innovation resources.The abundance of innovative resources determines the competition or synergy among the innovative populations in the region.At the same time，innovative resources can also influence the innovative populations in adjacent areas.The enterprise innovation population in the core area has a dominant influence on the evolution of the innovation ecosystem.

The empirical analysis in East China shows that the population dynamics method can be applied effectively to the study of regional association of enterprise innovation population.The relationship between the internal population and the population of the enterprises in East China is in line with the characteristics of population ecology.The growth of an innovative population can be studied using population dynamics.The dynamic models developed in the study can be used to describe the actual problems of innovative groups.
