This study  analyses the location determinants of eco-innovative firms in France between 2003 and 2013. The analysis is based on a dataset obtained after merging firm-level microdata on the location of new firms from DIANE Mercantil Register (Bureau van Dijk) and patents information from the OECD REGPAT (2018) database. As there is a growing pressure towards the development of innovation with the aim of reducing the environmental impact and a more efficient use of natural resources, our results provide evidence to contribute to the implementation of regional policies promoting the creation of eco-innovative firms and regional knowledge spillovers.
