Knowledge, innovation and space

This paper provides an overview of relevant topics in contemporary research concerned with global, national, regional and local knowledge and innovation dynamics. In particular, we highlight how the global scene is changing in the contemporary world economy that we char-acterize as a knowledge economy. We show how knowledge and knowledge dynamics is driving innovation in the large urban agglomerations in the old and in new industrialized countries with their concentrations of abilities and resources and their superior intra-regional and international geographical proximities. In relation to the large urban agglomerations we stress the role of (i) density and proximity externalities, (ii) the physical and cultural resource base of large cities, and (iii) the interactive dynamics related to learning and creativity.
