Interdependência e encadeamentos das exportações setoriais e os modais de transporte: um enfoque de insumo-produto

The main aim of this paper is to construct a complete analysis of exports and the mains transportation modals in the Brazilian economy. In order to implement this analysis we will use na inter-sectoral hybrid input-output matrix for the Brazilian economy. We will incorporate the modals of transport as a sector in this matrix. The global analysis will be based on the followed indicators: a) requirement coefficients, b) Rasmussem-Hirshman linkages, c) variability indexes and d) Field of Influence. The main results show that the road, rail and maritime models represent the key-modal for the Brazilian export. Moreover, the Steel sector exerts the strongest pressure on the rail and maritime modals demand and also represents the most important sector in the Brazil, because the linkages (forward and backward) of this activity affect and influence a great number of economic sectors.
