Clusters and Knowledge Economy
Bertrand Put simply, clusters are geographically close groups of interrelated specialized organizations. Two main historic reasons for industrial clusters were: easy knowledge exchange and the availability of skilled labor. I believe the arrival of the knowledge economy including all its communication technologies decreases the need for traditional regional clusters.
Stan Decrease the need: yes. But not end it: there are still valid reasons for regional clusters remaining.
Special Interest Group on Clusters
Editor Specialized business communities such as those on 12manage could be seen as a new type of clusters, without the need for geographical proximity. Make sure you are part of the SIG on Clusters at 12manage and Register ;-)
Cooperation and Competition
Juan I agree with Bertrand. We are seeing new types of clusters arriving without national or regional borders. Note that firms within clusters may be cooperative or competitive or even independent. This aspect remains unchanged in internet / knowledge economy.
