“…While research in the early 2000's was criticised for focusing on large technology-based firms and not accounting for differences in the innovation process between large and smaller firms (West and Gallagher 2006), more recent research has sought to address this imbalance (Van de Vrande et al 2009;Lee, Park, Yoon and Park 2010;Vahter et al 2014;Colombo, Piva and Rossi-Lamastra 2014) 2 .
