Guilty by association : a cross-industrial approach to sourcing complementary knowledge in the Uppsala biotechnology cluster

A wide range of industrial studies recognize the tendency of similar and related economic activities to co-locate in so-called industrial systems or clusters. While a cluster is defined by its cross-industrial relations the supporting and complementary role of cluster actors is seldom fully explored. This study will focus on the dynamics of cluster relations and give an account for the complementary nature of clusters by analysing anchor firms and complementary agents (such as specialized service providers and institutions for collaboration) in the Uppsala biotechnology cluster in Sweden. The empirical data used involves a triangulation of interview, survey and individual-based register data based upon a mapping of cluster actors active in 2002 and 2003. It is shown that both the formerly dominant pharmaceutical company and the local university have actively taken the role as anchor firms/organizations creating a local and dynamic milieu for biotechnology activities. Furthermore, it is shown that the local cluster consists of a variety of complementary agents contributing to knowledge spillovers and cluster competitiveness
