Knowledge networks and strong tie creation: the role of relative network position.

The proximity literature usually treats proximity in terms of common attributes shared by agents, disregarding the relative position of an actor inside the network. This paper discusses the importance of such dimension of proximity, labelled as in-network proximity, and proposes an empirical measurement for it, assessing its impact (jointly with other dimensions of proximity) on the creation of strong knowledge network ties in ICT in the region of Trentino. The findings show that actors with higher in-network proximity are more attractive for both other central actors and peripheral ones, which is further strengthening their position within the network. In detail, the centrally positioned actors repeat collaboration with other central actors in the network, as central actors gather more 'reputation', signalling that they will possess the needed knowledge resources. Relatively peripheral actors, either new or not so active inside the network, seek for collaboration with relatively central actors in order to tap on knowledge resources they do not acquire.
