Contemporary developments in public action constitute a field of research rich in informations on the logics of innovation. Institutional and organizational innovations participate in a dynamic of change that makes them worthy of interest in entrepreneurship. Indeed, the modes of organization, operation and intervention of communities and regions have been affected by a wave of innovations such as the SDLs and SDRs. We proceeded to construct the theoretical framework using the literature on innovation and entrepreneurship in the public sector. The literature review helped fuel the questioning of public entrepreneurship as well as its operationalization. Through a survey conducted among public officials in the Souss-Massa region, a relationship model is proposed. What forms has entrepreneurial innovation taken, and what roles have been played by entrepreneurs in the public sector. The process deserves to be studied in more detail to reveal, the triggers, the power plays, the time and place where it occurs, and the characteristics of the actors.
