Modified shift-share method, know as method of differential structure, was used. Analyzed data were obtained from the publications of IBGE. The analyses of the results for two group of crops considered for the region shows that after free trade, a relatively higher increase in production value, harvested area and productivity of national market crops in relation to export crops, even a decrease in their prices. However, a substituition of area of national market crops for by exports crops in seven states of the region. Given a superiority of export crops the performance, in most of the cases, was of little importance.
