“…In particular, these studies tend to focus on regions and show that industries are more likely to enter and more likely to survive in a region when related to existing industries in that region (see, e.g., Neffke, Henning, and Boschma 2011;Boschma, Minondo, and Navarro 2013;Essletzbichler 2015;Cortinovis et al 2017;He, Yan, and Rigby, forthcoming). The same is true for new technologies that are more likely to occur in regions when related technologies are locally present (e.g., Kogler, Rigby, and Tucker 2013;Colombelli, Krafft, and Quatraro 2014;Heimeriks and Boschma 2014;Van Den Berge and Weterings 2014;Boschma, Balland, and Kogler 2015;Feldman, Kogler, and Rigby 2015;Rigby 2015;Tanner 2016;Montresor and Quatraro 2017;Balland et al, forthcoming). In other words, related diversification is a dominant pattern in many regions.…”
