This paper explores the structural determinants of high-growth firm shares in Austrian regions. The regional level of analysis
allows to uncover regularities which are not detectable in firm-level studies. We find that lower mobility barriers, firm
exits and technological opportunities, measured by digitalisation intensities, and, to a lesser extent, agglomeration effects
are associated with a larger share of high-growth firms. The results suggest that comparisons of shares of high-growth firms
across countries and regions should consider differences in the industrial structures together with the often-emphasised differences
in policies and regulations.
