“…However, the debate in the academic community regarding whether agglomeration effects are caused by intra‐industry agglomeration (localization economies) or inter‐industry agglomeration (urbanization economies) has continued (Barufi et al, 2016; Cainelli et al, 2015; Fazio & Maltese, 2015; Glaeser et al, 1992). In recent years, scholars have begun to emphasize the differences in agglomeration effects among different industries and firms with different characteristics (Amara & Thabet, 2019; Antonietti & Cainelli, 2011; Badr et al, 2019; Beaudry & Schiffauerova, 2009; Duschl et al, 2015; Hartog et al, 2012; Hu & Liang, 2008; Kenney & Patton, 2005; Liang & Goetz, 2018; Neffke et al, 2011; Tao et al, 2019). In addition, scholars have noted the heterogeneity of firms (Ottaviano, 2011) and proposed that uncontrolled firm selection effects could cause endogenous problems and the overestimation of agglomeration effects (Ciccone, 2002; Henderson, 2003; Rosenthal & Strange, 2004).…”
