Evolution of regional clusters in nanotechnology. Empirical findings from Germany

Abstract

This article aims at establishing a wider understanding of the evolution of spatial clusters. It will be argued that the potential to generate regional growth is dependent on the way a cluster emerges. Two models of cluster formation will be distinguished in detail – start-up clusters and unrelated spatial concentrations. In its sectoral orientation the study is focused on nanotechnology, a key(technology)-industry said to contribute to new growth spurts in the industrialised world. By analysing the evolution of regional clusters in the Saarland and in Berlin-Brandenburg it will be shown that both types of cluster formation can be found in nanotechnology, demanding different modes of policy intervention.
