Cultural and creative activities are at the heart of the profound changes that are currently affecting urban societies, their territories and their development. It challenges public policies as they constitute a powerful vector of innovation, resilience of industrial territories, the production of specific atmospheres but also gentrification. Based on the concept of cultural scene, our project aims to analyze the complex embeddedness between cultural and artistic supplies, start-ups or creative entrepreneurs, and the socio-urban pattern. Beyond a theoretical and methodological reflection on the concept of scene, we will analyze conditions of emergence, visibility and development of scenes and study their strategic issues, especially for urban governments. Our work will focus on four main fields : Nantes, Angers, Grenoble et Austin (Texas, USA).
