Résumé : This paper argues that there is currently a need for new theory on transformative social innovation that is able to provide empowering insights to practice, especially in terms of how social innovation interacts with transformative change processes. It identifies three ‘pitfalls’ that such theory-building needs to confront, and presents middle-range theory development, together with a focus on social relations and the processes of social innovation, as three elements of a theory-building strategy that responds to these pitfalls. In describing the implementation of this strategy in successive iterations between empirical case study research and integrative analysis, critical reflections are drawn on each of the three elements of the theory-building strategy. Taken together, these reflections underline the importance of maintaining a reflexive approach in developing new knowledge and theory on new social innovation.
