Policy mixes for sustainability transitions: New approaches and insights through bridging innovation and policy studies

Abstract

There has been an increasing interest in science, technology and innovation policy studies in the topic of policymixes. While earlier studies conceptualised policy mixes mainly in terms of combinations of instruments to supportinnovation, more recent literature extends the focus to how policy mixes can foster sustainability transitions. For this,broader policy mix conceptualisations have emerged which also include considerations of policy goals and policystrategies; policy mix characteristics such as consistency, coherence, credibility and comprehensiveness; as well aspolicy making and implementation processes. It is these broader conceptualisations of policy mixes which are thesubject of the special issue introduced in this article. We aim at supporting the emergence of a new strand ofinterdisciplinary social science research on policy mixes which combines approaches, methods and insights frominnovation and policy studies to further such broader policy mix research with a specific focus on fostering sus-tainability transitions. In this article we introduce this topic and present a bibliometric analysis of the literature onpolicy mixes in both fields as well as their emerging connections. We also introduce five major themes in the policymix literature and summarise the contributions made by the articles in the special issue to these: methodologicaladvances; policy making and implementation; actors and agency; evaluating policy mixes; and the co-evolution ofpolicy mixes and socio-technical systems. We conclude by summarising key insights for policy making.
