R&D tax incentives (RDTIs) – here defined as R&D tax credits and other special incentives – must be viewed as the fiscal translation of conflicting goals among all players in the public and private sectors. A comparative analysis of the various national mechanisms among OECD countries as well as a focus on the French experiences will help us to identify and to understand the different types of constraints that RDTIs have to satisfy.
