The mechanisms driving the formation, evolution, and decay of network structures are the object of a growing interest (Ahuja, Soda, & Zaheer, 2008; Saavedra, Reed-Tsochas, & Uzzi, 2008; Zaheer & Soda, 2009). But little is known on how social infrastructures influence network structure evolution. Instead, research has more often focused on networks as mean to mobilize resources either for firms (Gulati, Nohria, & Zaheer, 2000; Zaheer & Bell, 2005) or social movements which aim at the formation new social infra-structures (Davis & Thompson, 1994; Diani & McAdam, 2003; Ingram & Rao, 2004). This paper looks at the links between social infra-structures and network structure evolution in an emerging academic field. It shows how social infra-structures influence tie formation and how actors embedded in a mature network create new social-infrastructures. Overall we find that team-assembly mechanisms and network structure evolution are shaped by social infrastructure and that the maturation of network structure is associated with actions by network members leading to the creation of new social infra-structures.
