Função de produção e eficiência técnica da agropecuária cearense

Abstract

There is an understanding among researchers on the importance of increasing agricultural productivity in Ceará and, therefore, it is necessary the realization of additional studies about the effects of production factors in relation to productive returns to identify in which municipalities are most significant. In thus sense, this work aims to realize the analysis of the production factors, regarding the technical efficiency and the technological heterogeneity of agriculture in 115 municipalities im Ceará. The data are secondary, compiled from the 2017 Brazilian Agropecuary Census. As an analysis instrument, it 1s used the model of stochastic production frontier in a Cobb-Douglas functional form admitting technical imefficiency. Based on the results, it is concluded that the municipalities of Ceará presented low technical efficiency and strong technological heterogeneity, while the most important production factors for the increase productive were the technology of saving land, labor and capital. With main conclusion, it appears that agriculture in Ceará is more intensive in production inputs and labor and the use of irrigation technologies has acted in reducing technical inefficiency.
