RESUMEN
Entrepreneurship has emerged as a key element for experimentation and niche innovation in sustainability transitions. Yet, its contributions beyond this initial stage and the multi-pronged role that entrepreneurs can play in transformation processes remain elusive. In response, we conceptualize and empirically illustrate how entrepreneurs can contribute to innovations within firms and to city-wide processes of change. With insights from small- and medium-sized enterprises in European and North American cities, we develop a framework encompassing eight intervention types through which entrepreneurs shape urban sustainability transformations. We propose avenues for future research to better understand the distributed role of entrepreneurship and how it can contribute to shaping and accelerating change toward sustainability across integrated levels of urban transformations.
