“…It is noted that knowledge spillovers not only occur in the local scale, but also take place at a global scale (Bathelt et al, 2004); not only occur through informal knowledge exchange, but also take place through formal networks of research collaboration (Ponds et al, 2010); not only represent spatial spillovers, but also perform relational spillovers (Maggioni et al, 2007). In the context of the globalization, informatization, and networking, the determinants of knowledge spillovers has undergone fundamental changes, most notably the ups of relational and capability proximity and the downs of geographical and cultural proximity Montobbio, Primi, & Sterzi, 2015;Ter Wal, 2014). Formal collaboration networks will be more important than informal knowledge exchange, because the former can occur over longer geographical distances (Ponds et al, 2010) and fresh and novel information from remote partners declines the risk of technological lock-in (Crespo et al, 2014;He & Fallah, 2014).…”
