Recent perspectives on a capabilities view of the firm often recognize the need for firms to develop an external organization. From a relational view of the industry, the external organization may include economic and non-economic exchange relationships. The decision to combine both types of relationships and its relevance for the firm can be linked to their role for accessing, generating and diffusing knowledge. More often than not, these decisions are however not unilateral. This paper discusses the potential role that Technological Centers (TC's), created by the collective initiative of some local firms, can play as part of firms' external organizations and emphasizes TC's role in connecting economic and non-economic exchange relationships. It is further suggested that the diverse motives and benefits perceived by firms in relating in and across the TC's and, in general, the relevance of sharing experiences within these contexts, should be seen in the wider context of firms' specific and idiosyncratic trajectories.
