“…In line with the studies on cooperation and integration, this research has involved analyses of the role of Euroregions, Interreg and other EU programmes in the economic development of border regions (McCall & Williamson, 2000). Additionally, the importance of transportation and border-crossing infrastructure, i.e., accessibility (Lundquist & Winther, 2006), in the economic development of border regions has been highlighted (Nelles & Sutcliffe, 2013). Finally, economic aspects of regional development in border regions have commonly been discussed in terms of cross-border inter-firm linkages, networking (Dimitrov, Petrakos, Totev, & Tsiapa, 2003;Geenhuizen, Knaap, & Nijkamp, 1996) and export flows (Ciżkowicz, Rzońca, & Umiński, 2013;Tykkyläinen & Lehtonen, 2008).…”
