Studies on industrial districts suggest that their innovative performance is strictly linked to their ability to absorb external knowledge. Yet, the existing literature provides few insights into the functioning of this process. This paper, focusing on leader firms located in a successful Italian furniture district, investigates whether they feed the district with knowledge absorbed from external sources, thereby behaving as ‘gatekeepers of knowledge’. Findings show that leader firms are well connected with knowledge sources; yet, linkages with districts firms are far more limited as are informal exchanges that, when they do occur, are mostly restricted to generic information.
