This article examines the relationship between local participatory policies and their market in France. The study stems from long-term field research drawing on a variety of materials: qualitative interviews with citizen participation professionals (consultants or civil servants), questionnaires, and an analysis of public procurement. This study depicts the way both the industry and the policies of citizen participation are structured in France. It also explores how French participatory policies are coproduced through mechanisms of competition–collusion between clients (mainly local public authorities) and providers (consultants). Finally, the study questions the effects of this market on local policies, showing that the market cannot be interpreted as an unequivocal sign of a decline in actors along with political stakes in public policies.
