RELAÇÕES INTERSETORIAIS E INTER-REGIONAIS NAS REGIÕES-PÓLO PARANAENSE EM 1995

The aim of this article is to analyse the intersectoral and interregional relations and to compare the produtive structure of the principal pole-regions in the economy of Parana, Brazil. To reach this it was used an interregional input-output table for the year of 1995 in which the state of Parana was dividid in four pole-reions: Curitiba, Ponta Grossa, Londrina and Cascavel. The main results show that the regional pole-regions of Curitiba and Londrina have a more complex productive structure. The sector of Pulp, Paper and Printing shows to be a key-sector for the Parana State economy and for the pole-regions of Curitiba and Ponta Grossa. Also the sectors of Non-Metallic Minerals and Transport Equipment were key-sectors for Curitiba. The Textile Industry had a fundamental role in the pole-region of Londrina and in the Parana State as a whole. The field of influence approach reveals that the main links are determined by the sectors directly connected to the pole-regions of Curitiba and Ponta Grossa.
