We understand a cluster as a certain number of value adding webs around single firms overlapping each other and being constituted by a connection of horizontal, vertical and lateral value adding activities contributed by different actors in proximity to one another which all act in relation to a specific industry sector. The actors have relationships characterised by interdependencies of different strength and quality that define the boundaries. Empirically this contribution is sticking to a firm cluster in the Danish - German border region in Southern Jutland/Danmark. We found global players with a high sensitivity regarding the importance of social capital in the process of value creation. Managers on the firm- as well as on the web-level are aware of the potential, but the border between the countries is by the same one border of the cluster as an value adding unit.
