Abstract:Although the achievements of eco-innovation gradually emerge in China, there exist some problems such as low level of adoption and insufficient transformation of achievements. The diffusion efficiency of eco-innovation needs to be improved. Based on the systematic review of the literature on the diffusion of eco-innovation at home and abroad in the past 20 years, we discovered that lots of researches have been focused on the influence of government regulation on the macro diffusion law of eco-innovation, and research perspectives have been gradually widened with constantly rich methods: in terms of the diffusion law and influencing factors of eco-innovation, scholars mainly use innovation theory, institutional theory, stakeholder theory and social network theory to analyze factors, such as government policy, stakeholders, social network, enterprise resources and capabilities from different perspectives; in the mechanism of eco-innovation diffusion, research methods of model simulation, case study, second-hand data statistics and questionnaire survey are discussed. According to the research conclusion, future research can further explore the process mechanism and influencing factors of the adoption of eco-innovation from the micro perspective, and clarify the relationship between the eco-innovation and general innovation in order to supplement the current theoretical and empirical research, providing guidance to the diffusion of eco-innovation in practice.
