The Interregional Trade in the Context of a Multirregional Input-Output Model for Spain



    () (Instituto L.R. Klein. Facultad Ciencias Económicas y Empresariales. Universidad Autónoma de Madrid. 28049 - Cantoblanco (Madrid))


In this paper we introduce the first version of INTERTIO, a Multiregional-Multisectoral model for the Spanish Economy. The model combines the spatial and sectoral dimensions assuming the theoretical and empirical possibilities and limitations of the interregional input-output model. The project uses most of the regional information available at that time, using non-survey techniques for the estimation of incomplete data. The model is based on the following two pillars: · A complete set of 17th regional input-output tables built (or updated) for 1995 (one for each of the 17th Spanish regions-NUT2). All of them coherent with the National input-output Table. · A set of interregional trade matrices, estimated indirectly for each kind of product and developed from the interregional transport flows, and valued using export prices. Apart from a brief description of the main underpinnings of INTERTIO, and the process of estimation, we focus on the strategy used for the estimation of this set of interregional trade matrices, using transport flows and value/weight relations indirectly deduced from detailed international trade statistics. Finally, the paper analyse the data obtained for 1995, offering a brief insight into the Sub-Balance of Goods of each region, and identifying the most important intra and interregional flows that are then analysed in relation to the importance of proximity and sectoral specialisation. En este artículo presentamos la primera versión del modelo INTERTIO: un modelo multiregional-multisectorial para la economía de España. El modelo combina las dimensión espacial y sectorial, asumiendo las posibilidades y limitaciones teóricas y empíricas del modelo input-output interregional de Isard. El modelo ha sido construido tratando de utilizar la mayor cantidad de información “oficial” existente, utilizando también técnicas de estimación indirecta para la información desconocida o no disponible. En este sentido, el modelo está basado sobre dos pilares fundamentales: · Una colección completa de 17 tablas input-output uni-regionales construidas (o actualizadas) para 1995 (una para cada Comunidad Autónoma) y armonizadas con los datos de la Contabilidad Regional y la Tabla Input-Output de España 1995 del Instituto Nacional de Estadística (INE). · Una colección de matrices interregionales de comercio, que han sido estimadas indirectamente para cada tipo de producto. A parte de una breve descripción de los fundamentos del modelo INTERTIO y el proceso de estimación, el artículo se concentra en la metodología utilizada para la estimación de las matrices de comercio interregional, mediante el uso de flujos de transporte y relaciones valor/peso deducidas indirectamente a partir de las estadísticas detalladas de comercio internacional. Finalmente, el artículo analiza los datos obtenidos para 1995, aportando una verdadera sub-balanza de bienes para cada una de las 17 Comunidades Autónomas y permitiendo la identificación de los principales flujos intra e interregionales y su contraste con lo recogido en la literatura acerca de la importancia de la proximidad geográfica y especialización sectorial en las relaciones comerciales.
