In recent years, there has been an increase in the number of studies on the challenges faced by science, technology, and innovation (STI) policymakers in confronting contemporary issues such as global environmental change, escalating inequality, and socio-economic health crises. Numerous studies have highlighted a critical disconnect between traditional innovation policies and the actions necessary to effectively address these grand societal and environmental challenges. These studies underscore the imperative of re-evaluating innovation policy frameworks to rectify this incongruity. Within this context, the third framework of innovation policy termed "transformative innovation policy", after the previous frameworks of innovation for growth and innovation systems, was presented with a more comprehensive approach to innovation. Identifying the characteristics of transformative innovation policy is crucial for the effective formulation and implementation of such policies. In this study, 41 selected articles were reviewed using the meta-synthesis method and 10 characteristics of transformative innovation policy were identified. Finally, considering that the transformation of socio-technical systems in transformative innovation policies is based on a multi-level perspective framework, these characteristics are categorized into three levels of niche, regime, and landscape.
