There is no other source on the subject of corporate innovation in France. The CIS questionnaire is the only national source of data on the frequency of innovation and its mechanisms.

Biennial

Data collection is carried out via the Internet and possibly by post (at the request of the company).

The collection period will run from April to September 2025.

Enterprise

The sample is drawn from a sampling frame constructed from the Système d'immatriculation au répertoire des unités statistiques (Sirus) according to a simple random sampling plan stratified according to activity, employment bracket, region and type of unit (independent legal unit, profiled company belonging to a foreign/French group with foreign/French subsidiaries) where possible. Allocations are calculated by combining a Neyman allocation based on the rate of innovation and a proportional allocation based on the number of innovative units. This makes it possible, on the one hand, to be precise about the survey's central variable (the rate of innovation) and, on the other hand, to question a reasonable number of innovative units in order to ensure satisfactory precision for questions concerning these units only.

13,400 profiled firms
