Evolução agrária do Nordeste paraense por contas sociais ascendentes: a inclusão das redes mercantis de insumos nos processos metodológicos e o cálculo dos níveis de endogenização

Abstract

The importance of this work is to analyze the dynamics of economic evolution in Northeastern Pará, in their fundamental structures of agricultural production, interpreting the results by means of sectoral impacts and spillovers of income and output in the economy. To this end, we applied the model accounts Agrarian Social Ascending Base (Input-Output Matrix) methodologically more comprehensive than the earlier approaches applied in the earlier work by Pires (2002) and André (2004) the same region, all derived Costa (2002abcd), including this work. Among other differences, the model was initially developed internally connected by the flow of products between the geographical size of the place, the state and national levels, where the production value is formed in the direction going from production to final consumption, or even the rural to urban, which will follow the direction of local production by domestic final demand. For this work, the way methodically adopted, as presented by Costa in 2008 in southeast Pará, incorporates primarily backward chains of inputs and investments that are reconstituted in the paths of the agents until the "first supplier" for both networks of price formation, as wages and gross margin (markup), which allows a differentiated analysis of the multipliers sectoral impacts, resulting in retention and spillovers analysis between income and product forms of production and their occurrences Structural geographical, examining the provisions of the centripetal and centrifugal forces, which allows you to make interpretations about the possibilities of local economic connections to the development, from the indexes of agglomeration.
