Dissipative Structure of Innovative Ecosystem in the Yellow River Basin Based on Brusselator Model
Taking the Yellow River Basin as the empirical object,the dissipative structure characteristics,formation and evolution of the in-novative ecosystem were explored.The formation process of the dissipative structure of the innovative ecosystem were deduced according to dissipative structure theory,and the dissipation level measure formula was derived from the Brusselator translation model,combined with the entropy weight Topsis method to measure and depict the dissipation level and evolution of innovative ecosystem in the Yellow River Basin from 2011 to 2020.The results show that the dynamic evolution of innovative ecosystems meets the conditions for the formation of dissipative struc-tures.Although the dissipation level of the innovative ecosystem in the Yellow River Basin shows a trend of increasing year by year,no dissi-pation structure has been formed during the study period.Compared with innovation investment,the innovation landscape is more important for its level of dissipation.The dissipation level of the innovative ecosystem in the Yellow River Basin shows a hierarchical distribution pattern of"downstream leading,midstream following and upstream catching".
