Evolução da produtividade total dos fatores do milho nas mesorregiões do estado do Paraná - Brasil

Abstract

This paper aims to measure the Total Factor Productivity (TFP) index of corn crop production from 2009 to 2016 and the TFP growth rate of the State of Paraná and its mesoregions, as well as to identify the geographic distribution and spatial dependence of the TFP growth rate, with emphasis on the use of statistics of spatial autocorrelation, I the Moran and thematic maps, of the PTF of these regions. The methodology used includes the Törnqvist index and Exploratory Spatial Data Analysis - ESDA. The results found showed that the TFP growth rate of Paraná State from 2009 to 2016 was 3.27%. Among said mesoregions, the Mid-South had the highest annual growth rate of 5.27% in the period. The West mesoregion confirmed a hypothesis, that is, it pointed to one of the best rates of productivity growth due to a higher concentration of livestock (poultry, cattle and pork) and industries (feed factories and slaughterhouses/ slaughterhouse). As to the geographic distribution and spatial dependence, the dependence was confirmed by the Moran’s I estimate, in which the three mesoregions that had a TFP growth rate above the state’s average formed a high-high cluster. Finally, it can be concluded from the results of this study that the TFP growth rate influences corn productivity and regional economic development by means of a more efficient use of inputs (Labor, Land and Capital).
