Based on a research-intervention carried out as part of a CIFRE thesis within the association "Auvergne Nouveau Monde" (ANM), the objective of this thesis is to identify, understand and evaluate the different determinants on which lies the participation of the stakeholders in the place marketing process of the "ANM" brand of territory. In order to do this, in a first part, in the fields of participatory democracy and place marketing, the meaning, scope and stakes of the participation of the stakeholders of a brand of territory are explained as well as their conceptual foundations. Then, in a second part, the field of research and the methodological approach to study the participation of the stakeholders of the brand "Auvergne Nouveau Monde" are exposed: the latter consists, first, of a contextualization work on the participation of stakeholders in the ANM place marketing approach and then, secondly, of a qualitative study carried out through 25 interviews with members of the association ANM, and, thirdly, the PLS (Partial Least Squares) approach to two models of structural equations (a model for the members of the ANM association and a model for the brand ambassadors, citizens of Auvergne) of the determinants of the participation of ANM brand stakeholders in the implemented place marketing approach. In a third part, the results of the validation of the two structural equation models of the determinants of participation based on a total sample of 295 respondents are presented and then discussed in order to delineate both the inputs, limitations, managerial implications and research prospects. The results show that attachment to the ANM brand has a positive influence on the participation of the stakeholders studied; correspondingly, the results indicate that this attachment to the brand is positively influenced by the feeling of regional belonging, organizational involvement (for members) and satisfaction with the ANM brand association
