“…Applications of this field of study include monitoring disequilibrium and domination during economic development, cultivating chances of cooperation and rivalry, creating milieu for shaping industrial competitiveness, and stimulating technological innovation (Belussi & Caldari, 2009;Funderburg & Boarnet, 2008;Mota & de Castro, 2004;Porter, 1998a;Rigby and Essletzbichler, 2002;Steinle and Schiele, 2002). While it is has been acknowledged that a group of related industries are co-located or geographically proximate (LaFountain, 2005), few studies have examined the spatial pattern of the co-agglomeration of industries to inform the above applications (Arbia, Espa, Giuliani, & Mazzitelli, 2010;Arbia, Espa, & Quah, 2008). As urban and regional economies grow, the spatial distribution and geographical co-agglomeration of industries may not necessarily follow the same patterns.…”
