Innovation Ecosystems in Catalonia: Exploring Location Patterns of High‐Tech Firms
Growth and Change, Volume 57, Issue 2, June 2026.ABSTRACT This paper analyses high‐tech firms' location determinants in Catalonia, Spain, using 2010–2019 firm data, and spatial models to assess spillover and industry‐specific factor effects. Results show that high‐tech firms, especially in services, are clustered in busy, wealthy cities with strong innovation hubs, while non‐high‐tech firms prefer ...

Named after the French–Belgian mathematician Eugène Charles Catalan, Catalan's numbers arise in various combinatorial problems [12]. Catalan's triangle, a triangular array of numbers somewhat similar to Pascal's triangle, extends the combinatorial meaning of Catalan's numbers and generalizes them [1,5,11].
