Análise de eficiência técnica e de escala pelo DEA aplicado aos custos da produção leiteira familiar

Abstract

Under economy and social areas’ perspective Agribusiness is an important country activity. Thus, the aim of the study is to identify technical and scale’s efficiency of milk-producing regions, especially in family agriculture, and also to build a ranking of productive efficiency considering the Brazilian production from 2008 to 2015. In the study the method used is the Data Envelopment Analysis –DEA oriented a inputs to amount the efficient from product milk regions inside the agriculture familiar. The sample, constitute for 13 milkproductionregions (Colorado do Oeste/RO, Ouro Preto do Oeste/RO, Angicos/RN, Caicó/RN, Bambuí/MG, Patos de Minas/MG, Unaí/MG, Orizona/GO, Itapuranga/GO, Itapiranga/SC, Rio do Sul/SC, Ijuí/RS e Teutônia/RS, thatowns data analysys the availableon Conab data base. The variables of analysis, outputs, used in the DEA model were lactating animals, liters of milk per animal and liters per day per property; already the inputs were characterized by variable cost, operational cost and management. The analysis of results showed that Bambuí / MG had the most efficient family production of milk, according to the efficiency ranking constructed through the DEA - BCC model. Two DMU’s have efficiency problems in scale, being Bambuí / MG and Itapuranga / GO and six DMU’s are considered technically inefficient. Colorado do Oeste / RO, Angicos / RN, Caicó / RN, Unaí / MG, Orizona / GO and Ijuí / RS. The municipality of Caicó / RN was considered to be the less efficient DMU, showing the necessity to minimize the costs per hectare: 60% in variable costs, 62% in operating costs and 25% in management.
