Transações inter-regionais e intersetoriais entre as macro-regiões brasileiras

The aim of this article is to study the evolution of the productive structure of the five Brazilian macro regions in the years 1985 and 1995 by means of interregional input-output tables estimated from the national tables published by IBGE. The results showed key-sectors in the five studied regions, showed that the Southeast region is very independent from the other Brazilian regions and that the South and Northeast regions alternated in the second position in terms of the dynamics of their productive structures, followed by the Central-West and North regions. It was possible to detect relative dynamics in the productive structure of the Northeast region, as well as the existence of greater integration between that and North region in 1995, which may be indicating the existence of a possible development pole between those regions. Finally, greater independence was verified among the Brazilians regions, being relatively plausible to point at the growth of the integration of the national productive structure with the exterior in 1995 compared to 1985
