“…Regions characterised by higher R&D investment also tend to experience greater knowledge spillover (e.g., Audretsch and Lehmann, 2005), and venture sustainability is influenced not only by traditional economic factors, such as market potential (e.g., Pires, 2005) or demand sophistication (e.g., Buesa, M., Heijs, J., Baumert, T., 2010; Lindic, J., Bavdaz, M., Kovacic, H., 2012), but also by the opportunity to access the knowledge and technology generated by surrounding universities (Audretsch and Lehmann, 2005). Thus, the knowledge environment can be a source of regional competitive advantage (e.g., Fritsch, 2008;Pe'er and Vertinsky, 2008;Tappeiner, G., Hauser, C., Walde, J., 2008).…”
