ABSTRACT
Empirical observations reveal that in a wide range of industries’ firms tend to cluster in geographic space – biotechnology is no exception. In the United States, one finds biotechnology concentrations in San Diego, South San Francisco, the Research Triangle Park in North Carolina, and the region off Route 128, just north of Boston (for a more detailed mapping, see Stuart and Sorenson 2003). In Germany, biotechnology clusters are located for example in Bavaria and in the Rhineland (Zeller 2001). 1
