摘要：The purpose of this study was to analyze the technical efficiency of citrus producing properties in Sao Paulo state, in 2009 and 2010. For this, producers were interviewed; non–parametric data envelopment analysis approach was applied to calculate levels of technical efficiency, and an econometric approach was applied to establish technical efficiency determinants. The results showed that a great part of Sao Paulo citrus producing properties works inefficiently and the variables that mostly contribute to increase efficiency are “producer schooling “ and “experience as rural producer”.
