Abstract:The innovation ecosystem is an important means for the energy-saving and environmental protection industry to integrate innovative resources, create innovative advantages and enhance industrial competitiveness to break down the technical barriers in developed countries. Based on the analysis of defining the connotation and characteristics of the innovative eco-system of energy-saving and environmental protection industry, the six innovative organizations, the three innovative populations, the internal and external innovation environment were clarified from the perspective of innovation ecology, and the innovative eco-system model of energy saving and environmental protection industry was built. Futhermore, based on the theory of multi-center governance, this paper analyzes the governance mechanism of the innovation eco-system of energy saving and environmental protection industry , including regulatory mechanism, reputation mechanism, intellectual property protection mechanism, demand feedback mechanism, synergetic mechanism and information disclosure mechanism,providing a reference for system optimization.
