摘要:Why geo-located social networks matter in how knowledge is created and diffuses in space? According to a central tenet in social sciences, network position of individuals explains much of information access (Ibarra, H.1993), control of flows (Newman, M.E.J.2005), and thus the outcomes of new knowledge creation (Burt, R.S.2004).It is also widely recognised that social ties and personal acquaintance reduce transaction costs and enhance the efficiency of mutual learning (Borgatti, S.P.et al.2009).However, we still need to better understand how social ties form and evolve in space (Juhász, S.and Lengyel, B.2017) and how they contribute to socio-economic and technological development (Lengyel, B.and Eriksson, R.2017).With the large ICT-related datasets now available, we can investigate the structure and dynamics of social interactions at an unprecedented scale (Lazer, D.et al.2009).Yet, most empirical works on large-scale social networks neglect the very geography inscribed in all socio-economic relations (Fernandez, R.M.et al.2004), thus falling short of grasping the economic, social, political, and institutional diversity of regions.
