Introduction: (Journal of Inspiration Economy vol. 2 issue 2)

Contemporary economies are inescapably service economies, innovation economies and sustainable development economies. First, for several decades now, the tertiary sector has been the main source of wealth and job creation in all developed countries, and emerging economies provide another example of what can be called the Fisher–Clark–Fourastié law, reflecting a sectoral shift of the workforce from the primary to the secondary and then to the tertiary sector. Second, innovation and knowledge are considered the main drivers of socio-economic progress. While this argument is not new, the magnitude and rapidity of innovation and cognitive dynamics are greater than ever. This is the reason why modern economies are often labelled permanent innovation economies or knowledge economies. Finally, these economies are, or aspire to be, sustainable development economies, and green economies in particular. Thus, environmental issues are no longer considered only militant and utopian concepts but are now a major part of socio-economic and political discourses.
