Study on the Evolution of Dissipation Structure and Spatial Characteristics of Regional Innovation Ecosystems in the Yellow River Basin
The regional innovation ecosystem is a crucial foundation and driving force for economic and social development.Based on the a-nalysis of the formation process and evolutionary mechanisms of dissipative structures in regional innovation ecosystems,and drawing on the translated Brusselator model,criteria for determining the formation of dissipative structures in regional innovation ecosystems were derived.On this basis,an indicator system for the evolution of dissipative structures in the Yellow River Basin's innovation ecosystem was developed.The study examined the evolution of the dissipative structures in the Yellow River Basin's innovation ecosystem from 2013 to 2021 and used the Getis-Ord Gi∗ index method to analyze its spatial distribution.The results indicate that within the Yellow River Basin,the provinces of Shandong,Henan,and Sichuan have established innovation ecosystem dissipative structures.Among them,Shandong exhibits a stable devel-opment trend in its dissipative structure level,while Sichuan and Henan have experienced periodic fluctuations in their dissipative structure levels during their formation.The determination values for the evolution of the innovation ecosystem's dissipative structures in the upper,middle,and lower reaches of the Yellow River Basin show an upward trend.The dissipative structure level is the highest in the lower rea-ches,followed by the middle reaches,with the lowest level in the upper reaches.In the Yellow River Basin,the innovation ecosystem's dis-sipative structure in the lower reaches shows hotspot clustering,the middle reaches display a secondary hotspot-secondary coldspot clustering centered around Shaanxi Province,and the upper reaches have not yet formed significant coldspot clustering.
