In the mid-1990s Catalonia is a region that accounts for a fifth of Spanish output of goods and services, and heads the Spanish regions in income per capita together with the Balearic Islands and Madrid, at 95% of the European community average. The research points out that between 1955 and 1995 the production of goods and services multiplied by a factor of 2.5. It also notes that the growth of Catalonia is basically produced supported by private investment, as the public capital involved in this development is significantly below the Spanish average. This research is part of the collaboration between the BBV Foundation and the Valencian Institute for Economic Research (IVIE) for the study of the regional Spanish economy.
