Economic Complexity Analysis

The goal of this paper is to elaborate an empirical analysis of the relationship between Critical Raw Materials (CRMs) and environmental technologies.Using text mining techniques to parse and analyse patent descriptions, we provide a thorough empirical exploration of (i) the dependence of green technologies on CRMs; (ii) the countries that lead the demand of CRMs; and (iii) the countries that are more exposed to global demand for CRMs.Framed in the context of recent policy debates on the viability of the green transition, our study points to criticalities associated to both the evolution of green technology and to the spatial network of demand and supply of CRMs.
