Presentation from Damien Demailly at the opening session of the first Say Congress, organized at Boulogne-Sur-Mer by the Research network on innovation and the Jean Baptiste Say international Society. This congress is dedicated to the economic thought of industrial revolutions: innovation, entrepreneurship and business cycles.

The presentation from Damien Demailly focuses on the recent use of the history if industrial revolutions in the sustainability debate. It nuances the idea of a new and green “industrial revolution” and suggests – based on history – to go beyond technology when considering innovation for sustainable development.
