“…Whilst many firms locate in clusters, some are seen to have their presence in form of multiple establishments across multiple clusters (McCann and Folta 2008). Although several studies have discussed the facilitators of firms' location choice of (first) cluster location (Berchicci, King, and Tucci 2011;Cooper and Folta 2000;Pe'er, Vertinsky, and King 2008;Zaheer, Lamin, and Subramani 2009), very few studies investigate the choice of locating in multiple clusters exercised by the firms (e.g., Ernst 2002;Storper 2011). More specifically, very little is known about what drives a firm to expand into multiple clusters.…”
