Differenciated Knowledge bases and varieties of Regional Innovation Systems

This article introduces a theoretical and analytical framework for discussing regional development and regional advantage with reference to a regional innovation system strategy. It uses the differentiated knowledge base approach to transcend the traditional codified–tacit dichotomy of knowledge, and for providing a trans-sectoral understanding of economic activities. Different regional innovation systems are presented and described. The discussion of various types of regional innovation systems is contextualized using a variety of capitalist perspectives. The article concludes by discussing the question if regional innovation systems can exist.
