          Abstract

          Resumo O objetivo deste trabalho é analisar a evolução espacial e temporal da produção agropecuária e das produtividades líquidas do trabalho e da terra na agropecuária brasileira para os períodos censitários de 1995/1996, 2006 e 2017. Os resultados mostram que o valor da produção agropecuária cresceu 3,65% a.a. entre 1995/1996-2017, e esse aumento acompanhou o crescimento da produtividade da terra e do trabalho, que variaram entre 2,55% e 3,42% a.a. respectivamente, ainda que regionalmente de forma desigual. Quanto aos resultados dos impactos das variáveis explicativas sobre a produção, a magnitude dos efeitos totais observados dividiu-se em diretos e indiretos, com a presença de efeitos de realimentação (feedback). Portanto, além de os insumos explicarem o crescimento, os efeitos de dependência espacial entre as Regiões Geográficas Imediatas (RGIs) também apresentaram impactos significativos. Conclui-se, portanto, que o crescimento da produtividade na agropecuária brasileira nas RGIs guardou estreita relação com suas vizinhanças no curto e no longo prazo.

          Abstract The objective of this research was to analyze the spatial and temporal evolution of agricultural production, and the net productivity of labor and land in Brazilian agriculture for the 1995/1996, 2006 and 2017 census periods. The results demonstrate that the value of agricultural production raised 3.65% a.a. throughout the censuses period, while land and labor productivities increased 2.55% and 3.42% a.a. respectively. The total effects observed was divided into direct and indirect, in other words, it was verified the presence of feedback effects. Therefore, in addition to the inputs that explain the growth on production and productivity, the effects of spatial dependence among the Immediate Geographic Regions are also relevant. The conclusion is the productivity growth in Brazilian agriculture in the RGI mantains a spatial dependence with its neighborhoods in the short and long term.
