Abstract:From the perspective of ecology, the innovation ecosystem researches the interactive relationship between innovation subject, innovation content, innovation resource and innovation environment, which is essentially a biological metaphor of innovation system. The innovative ecosystem is a new way to explore the sustainable development of resource-based city. Firstly, from the four aspects of innovation subject, innovation content, innovation resource and innovation environment, the driving factors of innovation ecosystem of resource-based city are defined. Secondly, the key driving factor recognition model based on DEMATEL method is constructed, and the influence degree, affected degree, center degree and reason degree of each driving factor are analyzed. Thirdly, drawing lessons from the division of the development stage of resource-based city, this paper divides the development of innovative ecosystem of resource-based city into four stages: germination stage, growth stage, mature stage and differentiation stage, and analyzes the key driving factors, agglomeration mechanism and diffusion mechanism in each stage, the realization mechanism of innovative ecosystem of resource-based city is revealed.
