“…Geographical proximity facilitates spillovers of knowledge because, as knowledge is intrinsically sticky (Winter, 1987), it permits close and repeated interactions between actors, allowing them to understand, identify and integrate relevant knowledge (Antonelli, 2001;Arundel & Guena, 2004;Boschma, 2005;Breschi & Lissoni, 2009;Jaffe, 1989;Verspagen & Schoenmakers, 2004). Confirming this, a vast body of empirical research finds that geographical distance is a barrier to knowledge spillovers (Breschi & Lissoni, 2009;Verspagen & Schoenmakers, 2004;Wang, Meijers, & Szirmai, 2017). From the point of view of peripheral regions, particularly those located very far from centres of excellence, a greater degree of agglomeration economies implies lower prospects of benefitting from the technological advancements of core regions, causing them potentially to fall behind on the technological ladder.…”
