<i>'This book makes important contributions both to theory and public policy. It develops the understanding of the concept national innovation systems by confronting it with the reality of ten developing and transition countries from four different continents. The case studies apply the concept to different sectors and technologies spanning from mining in Nigeria to the health sector in Brazil. Common themes are the importance of informal institutions and the systemic interdependence between national patterns of innovation on the one hand and patterns of interaction among firms on the other. One lesson that policy makers can learn from this diversity of experiences is that getting to know the specificity of your own national innovation system, including how it is linked to the rest of the world, is a prerequisite for smart policy and necessary in order to overcome path-dependency and social exclusion.'</i><br /> --Bengt-Ake Lundvall, Aalborg University, Denmark
