This article aimed to determine the productive efficiency of sugar and alcohol industries located in the state of Mato Grosso do Sul (MS) and to verify which efficient industries can be references to inefficient ones. A quantitative methodology was used with secondary data, obtained from official organizations, such as: Brazilian Institute of Geography and Statistics (IBGE) and Sugarcane Industry Union (UNICA), using Data Envelopment Analysis (DEA) non-parametric tool that assesses the relative technical efficiency of production units. The years analyzed were 2000, 2005, 2010 and 2015, with one input (sugar cane) and two products (sugar and ethanol). These periods were chosen following IBGE precepts, in order to determine if the companies are compared to past periods and also because of the (in) efficiencies over the periods in the Decision Making Units (DMU). The DEA-CCR model with input orientation was chosen to obtain the sugarcane industries classification. The results showed that the installed companies presented medium to high efficiency in the use of sugarcane. The conclusions showed that the average efficiency decreased between the analyzed periods, however, none of the units presented low efficiency, not even those that were paralyzing the activities.
