Examining the 'who' (agents), 'how' (policy instruments) and 'why' (societal legitimacy) of the governance process, this book presents a conceptual framework about the governance of change in socio-technical systems. Bridging the gap between disciplinary fields, expert contributions provide innovative empirical cases of different modes of governing change. The Governance of Socio-Technical Systems offers a stepping-stone towards building a theory of governance of change and presents a new research agenda on the interaction between science, technology and society.
