“…By virtue of the sheer size of their research infrastructures, scientific instruments and the generous budget they manage, public procurement from Big Science Centers (BSCs) can be an important tool for the innovation policies of governments funding them. While BSCs are purposefully built to address broad and complex research questions, their Member States (MS) fund them not only for the promise of scientific discoveries, but also for the the economic and societal spillovers they can generate (Autio et al, 2004;Florio et al, 2018a;Helmers and Overman, 2017;Vuola and Hameri, 2006). For this reason, the procurement rules of several European BSCs incorporate, or are inspired by, the so-called juste retour concept.…”
