This PhD thesis presents the local communities decisions toward the adoption of responsible innovations, the local communities being seen as public organizations. This analysis is carried out in a context of awareness of public organization' social responsibility. We perform a comparative study between the French and the Romanian communities and we propose a decision-making process of the public organizations. The decision is seen as a « meeting » between the mayors values, as the community decision-makers, the different stakeholders, playing an important role in the community's activity, and the several options available to the mayors. Moreover, the decision-making represents an evolution from the need to adopt the responsible innovations to the final decision of action or non-action ; this decision-making is under the stakeholders influence which involves the isomorphic pressures. The way that the mayors react to these influences lead us to identify 3 categories of adopters : the first adopters, the persuaded adopters and the hesitant adopters. These elements allowed us to confirm and complete the model from the theoretical part.
