While innovation plays a significant role in such transitions, policy makers and the scientific community have become increasingly aware that the deliberate destabilization of existing socio-technical regimes—including associated institutions and technologies—is also often necessary. However, such aspiration is politically contested. This paper presents the Endowment-Practice-Institutions (EPI) Framework to study the contestation of institutions underpinning socio-technical regimes. By integrating key theories from Institutional Sociology and Political Economy, the framework conceives actors’ capability of influencing institutional structures to be dependent on their institutional work practices and the various endowments that enable these practices. We present Japanese coal policy as an example to illustrate how the framework can be used to assess actors’ institutional work and their influence on institutional outcomes. In addition to providing new theoretical insights, the framework helps to systematically analyze agency-driven mechanisms pertinent for the maintenance or destabilization of socio-technical regimes.enjournal article
