La base de datos C-intereg sobre el comercio interregional de bienes en España: método y primeros resultados (1995-2006)

Although the regional input-output charts and other sources of statistical information provide general information about the trade that some autonomous communities have “with the rest of Spain”, the main estimations of the interregional trade have occurred within the context of academic research projects. In this paper we put forth the method used to estimate interregional trade within Spain based on the C-INTEREG Project. The presented historical series covers the period 1995-2006 and it includes the details of 16 branches, 6 modes of transportation (road, rail, ship, aircraft, pipeline and powerline) in physical and monetary units. In this way, the INTEREG-C database is presented as the most comprehensive estimation of the interregional trade (NUTS 2), the first being at the provincial level (NUTS 3). The paper also includes a brief analysis of the main results, which shows the relative importance of domestic trade versus international trade.
