Resumo
The analyses of the dynamics of the crops composition in the State of Goiás was first started by Yokoyama (1988). Here, is made a continuity of this work and methodology enlargement elements like maps and graphics to better scrutinize the phenomenon throw the use of shift-share rates. Further socio economic inferences are based in agricultural frontier´s theory. The mathematical methods and uses, of the shift-share rates, are discussed. Using this model, the area effects are decomposed into scale and substitution effects, and it shows the geographic location effects for the selected microrregiões, and for this also the production effects. The agricultural frontier model is presented in basics ideas. The indices are presented for individual and the set of crops in the microrregiões and so are fluctuation of production of the set and location of crops in the State of Goiás. The results point changes in the crops composition in the State of Goiás. Staple food production in the new context, despite changes of territory of crops, it maintains important role in National context. It presents results about the important discussion that involves sugar-cane expansion, relations to soy-beans and cattle and conclusions about crop relations to ´cerrados´ area. The crop period goes is from 1990 to 2009.
