The Working Paper analyses the performances of the Walloon innovation system in 2008. This analysis concentrates on the six dimensions of the innovation system: knowledge development, human resources, R&D exploitation, innovation absorption capacity, entrepreneurial skills and financing capacity.  These foundations are evaluated by comparing the performances of the Walloon innovation system with the performances of innovation systems of other countries and regions in Europe. They were chosen for their socio-economic proximity to the Walloon region. The examination of the Walloon innovation system reveals a problem that is essentially connected with the capacity to turn research and innovation efforts into economic results that are sufficient for the Region.
