Knowledge and Innovation in a Mature Cluster : An Economic-Geographical Study of the Aluminium Product Cluster in Småland and Blekinge, Sweden

The thesis aims at understanding mechanisms behind knowledge generation and learning in a mature cluster by analysing firms in south-east Sweden engaged in the development and manufacturing of aluminium products. The point of departure is in concepts and assumptions related to spatially concen-trated systems of similar and related firms and industries, such as agglomera-tions, clusters or innovation systems. Three sets of empirical analyses have been conducted: a mail survey, a series of in-depth interviews and a register-based analysis. The analyses focus on three themes: inter-firm relations, the embeddedness of the clustered firms in the region, and the role of labour and labour mobility in cluster development. It is shown that also in a rather mature and low-tech cluster, firm competi-tiveness rests on continuous knowledge upgrading and innovation. In general terms, firms in this cluster do have business relations with other firms at all different spatial scales. While there are manifold buyer-supplier relations within the cluster, most firms have their most important linkages outside the region. The firms regard themselves as part of a cluster and various mecha-nisms contribute to this. There is a strong sense of trust and loyalty, and this applies in particular to those engaged either in some of the more organized supplier networks or the regional cluster initiative Aluminiumriket. Finally, the cluster does not seem to constitute a very fluid labour market for special-ised skills. Labour mobility between firms in this particular cluster seems to be fairly low
