Abstract
The growing of agricultural has been object of many researches that highlights
the importance of this sector in North region. The economic geography has showed
that economics phenomenon can present spatial dependence, mainly considered the
diffusion effect. The objective of this work is to verify the existence of spatial cluster
of agriculture in theBrazilians microregions, with emphasis in role of the variables
livestock cattle and permanent and temporary crops for de years of 1990 and 2013. The
methodology used was the explorative analyze of spatial data (EASD) by calculation of
I Moran index global and locally and clusters analyzes. The results show the existence
of spatial autocorrelation in the agricultural among Brazilian microregions, in the
variables research in this study. The also evidence of a migration of these productions
from South and Southeast regions to Middle-west and North regions.The estimated
econometric models show the existence of a strong spatial effect on livestock production
in Brazilian micro-regions.These also show the existence of spatial convergence in the
Brazilian livestock production.
