“…Such geographic considerations include access to markets for inputs and products (King et al, 2003;Rosenthal and Strange, 2003;Andersson and Hellerstedt, 2009), proximity to human capital (Glaeser et al, 1995;Simon, 1998, Simon andNardinelli, 2002), positive knowledge spillovers from firms (Crescenzi, 2005), universities (Braunerhjelm et al, 2000) and buyers and sellers (Ketelhohn, 2006;Maine et al, 2010), and negative spillovers from increased competition (Rosenthal and Strange, 2003;Tallman et al, 2004).The influence of geographic distance also has been reported to vary across high-tech sectors (Arauzo-Carod and Viladecans-Marsal, 2009;Anselin et al, 2000). However, no study has systematically examined the role of geography along all dimensions across the spectrum of high-tech industries.…”
