This paper investigates the link between international networks and export intensity using data from the UK Community Innovation Survey. The most important finding is that intra-firm links are associated with an approximate doubling of exports. Surprisingly, our examination of interactive size effects and intra-firm linkages does not support our prior that the smallest firms are the ones most likely to benefit from linkages. Rather, it is seen that firms with turnover in excess of ?2.3 million, are the best equipped to realise higher exports from their linkages. This result is in line with the view of Cassiman and Veugelers (2002) that only firms that can sufficiently protect proprietary information can expect to benefit from such cooperation.
