The aim of this article is to analyze the factors that influence French industrial firms in their eco-innovation performance. An econometric model for analyzing the characteristics that are conducive to the development of eco-innovations is tested using individual data on innovation, representative of all French industrial sectors (CIS 2008). The results highlight the structuring role of firms' internal characteristics, especially the positive role of the innovative activity of the firm. Also, they show the great influence of the firms' external environment, in particular, the rate of sectoral adoption, on the firm's eco-innovation intensity.
