摘要：One of the most important tasks for constructing regional use and supply tables is based on the accuracy of the estimates of interregional trade flows, which can be carried out indirectly by non-survey statistical and mathematical methods or directly by surveys. The former methods allow estimating interregional trade at a low cost though assuming many times certain arbitrary hypothesis. Nevertheless, the enlargement of a yearly yet existing survey with a wide coverage of firms, such as the Annual Regional Accounts in Andalusia (Spain), elaborated by the Institute of Statistics of Andalusia, can provide two important advantages at a low cost: the estimation of interregional trade for a certain region and the estimation of the structure of distributive channels for each product and industry, both on a yearly basis. Thus, this paper makes a proposal for incorporating interregional trade flows to the present yearly regional accounts survey for the Andalusian economy.
