Southeastern Pará is an extraordinarily dynamic region. There were large cattle ranching projects, financed in the 1960s. Expansion of peasant agriculture, mineral projects and gold prospecting followed the ranching projects. Also important structural transformations reinforced
the role of the urban centres and the local rural bases in the logistics of new economic sectors conditioned by the presence of Companhia Vale do Rio Doce (CVRD), in the region since 1985. This article presents the results of an input–output analysis of the investment programme of CVRD
from year 2004 up to 2010. The main findings are that the mineral sector has achieved a considerable influence over the economy of Southeastern Pará, so that during the cycle of investments each 1% in the growth of the mineral production creates growth possibilities of about 0.83% for
the agricultural sector and about 0.86% for the local urban sectors. Considering just the production growth, a percentile point will imply growth at, respectively, 0.73% and 0.76% for those sectors. For the economy of the rest of the state of Pará, those elasticities would be, incorporating
the investments, 0.80% and, without them, 0.68%. For the economy of the rest of Brazil they would be, respectively, 0.88% and 0.78%.
