The Southeastern Pará has been an area of extraordinary dynamics in the Brazilian Amazonia. There were allocated the great cattle ranching projects financed by SUDAM in the sixties and seventies, which confronted the moving frontiers of both peasants and gold miners. Main area of the Vale do Rio Doce Company performance in Pará, the meso-region has also seen the transformation of mercantile agents into big fazendeiros. The available literature presents two hypotheses on the development of the region. First, the mineral extraction is an enclave producing low, if any, local development impulse. Second, that the agrarian economy develops a boom-collapse pattern meaning that, after a strongly ascending phase due to wood exploitations and extensive cattle raising, sharp production crises would take place ending with permanent stagnation. The article tests, starting from a amplified model of exports base multiplier (PRED, 1966; ROMMER, 1986, 1990; FUJITA; KRUGMAN; VENEBLES, 2002), those hypotheses using a series of input-output matrices issued with CS methodology (COSTA, 2006c, 2008a, 2008b, 2009).
