A Model to Test How Diversity Affects Resilience in Regional Innovation Networks — •Sergi Lozano¹ and Alex Arenas² — ¹ETH Zurich, Swiss Federal Institute of Technology, Zurich, Switzerland. — ²Universitat Rovira i Virgili, Tarragona, Spain.

Research about resilience on complex systems has been commonly addressed from a structural point of view, relating this concept to the preservation of the connectivity against the suppression of individual nodes or links. This perspective coherently encompasses the analysis of resistance of networked infrastructures to structural damage (e.g. power grids, transportation and communication networks), but not necessarily other sort of socio-economical systems. Here we associate the resilience concept to the capability of a social organization to keep acceptable levels of functionality against external socio-economic disrupting factors that do not imply necessarily destruction of existing links.

As a particular case of study, we show how diversity of the organizational characteristics (both structural and related to individual*s behavior) improves resilience of regional innovation systems to uncertain socio-economic scenarios. We reanalyze the conclusions of a classical text about regional development (Saxenian 1994), comparing the evolution of two industrial districts, by first making a qualitative analogy in terms of resilience and, second, building up a simplified model of innovation systems that support quantitatively our argumentation.
