Chapter 7 The Dynamics of Industrial Clustering in the German Enterprise Software Sector

Enterprise software is a predominant sector in the European software industry. Four of the five largest European software companies are found in this sector. Interestingly, two of these — among them SAP as one of the two global market leaders — are located within the same industrial agglomeration in South-Western Germany. This agglomeration, the SAP cluster, further consists of enterprise software SMEs forming a ‘satellite system’ centred around the large players, which fosters the formation of ‘mutualistic symbiotic’ relationships between large and small firms. At first sight, cluster formation in the context of the enterprise software industry might seem perplexing considering that traditional rationales of agglomeration economies seem obsolete in an environment where advances in communications technology would permit companies to locate in any location within a modern developed economy instead of concentrating in proximity to each other or to major players in the industry. This chapter explores possible explanations of this agglomeration phenomenon based on patterns of competition, collaboration and the formation of social capital between smaller firms and large anchor firms. The findings of a comparative analysis between the SAP cluster environment and two categories of controls (firms in other agglomerated environments and those unaffected by agglomeration effects within Germany) show that SAP cluster SMEs might simultaneously benefit from heightened intensity of competition and a more pronounced inclination towards collaboration. Moreover, the role of social capital derived from SAP as anchor firm clearly differentiates SAP cluster participants from firms located within other environments.
