The chapter is dedicated to research on innovations in policy and governance, understood as the active creation and expansion of innovations in the shaping of collective orders. From this perspective, we first show that two parallel innovation discourses, one managerial and one analytical, can be distinguished in historical retrospect. We then present three current research strands on innovation processes in policy and governance. First, works on policy convergence and change are based on a functionalist understanding of politics, which ties in with an evolutionarily influenced philosophy of science. Second, studies on transfer, diffusion, and convergence implement an evolutionist paradigm, according to which similar problem situations in different contexts trigger comparable transformation processes. Third, research on policy mobilities, translation, and assemblages places the focus on practice-discourse formations, whose expansion requires translation into local contexts. In the final part, we identify overarching trends in the literature reviewed and desiderata for future research.
