Matuschewski A. (2006) Regional clusters of the information economy in Germany, Regional Studies 40, 409–422. In Germany, similar to other countries, enterprises that belong to the information economy (IE) tend to concentrate in a few regions. The paper takes a closer look at the reasons and driving forces for regional clustering within the IE. It is based on the analysis of three German IE clusters: Hamburg, Dresden and the Technology Region Karlsruhe. The analysis follows an explorative, actor-oriented approach using a mixture of qualitative and quantitative empirical methods. The paper concentrates on selected aspects of clustering, questioning the relevance of different theoretical concepts for regional clusters within the IE. It confirms that regional clusters rely on sectoral and regional factors that shape specific regional development paths. Matuschewski A.
