The thesis focuses on the practices deriving from Sustainable Development (SD) and Corporate Social Responsibility (CSR), and on the way these practices transform the French hotel industry. An intermediary concept of SD/CSR process is introduced in order to specify these practices and discourses. This allows showing that the SD/CSR processes are the result of successful and powerful actor strategies inside the hotel industry, from both luxury hotels and franchised hotels. These processes contain new forms of differentiation strategies, which contribute to strengthen those two types of hotels and the sectorial dynamic. SD/CSR processes inclusion in luxury hotels is achieved through outsourcing, whereas franchised hotels integrate them directly into their production process. SD/CSR processes are standardized on an industrial model of production. The thesis proves that the specific type of SD/CSR integration participates to the deterioration of the wage labor nexus, especially regarding the working conditions and the forms of mobilization of the employees. It is also shown that, considering the specific way in which the SD/CSR processes are implemented, they serve the corporate strategy, strengthen the technical and gendered division of labor, intensify labor, and renew mobilization discourses around the theme of nature protection
