Mensuração do desempenho produtivo de unidades de produção agricola considerando aspectos agroeconomicos e agroenergeticos

Abstract

O presente estudo enfoca a análise da eficiência de unidades de produção agrícola, observando o conceito de sustentabilidade. Especula-se sobre sistemas de mensuração de eficiência técnica relativa considerando aspectos econômicos e energéticos, separada e conjuntamente, e fortnas de mensuração parcial, através do método de comparação de grupo baseado em índice de produtividade parcial, e agregada, através da Análise Envoltório de Dados - DEA. Aplica-se os diferentes sistemas de mensuração a um conjunto de produtores de arroz irrigado localizados no litoral-sul catarinense. Abstract : Through of the analysis of your performance, the production units can measure survival and maintenance capacity front to the environmental exigencies in that they are situated. The production efficiency measure provide support to the inputs and productive process management, comprehension of the technical and economic decision making process and identification of the better adapted strategies and practices (benchmark or benchleaming). The present study focuses on the efficiency analysis of agricultural exploration units and observe the sustentable concept. Its speculates about the relative technical efficiency measurement systems considering: (a) economic and energetic aspects, separate and combined; (b) measure forms: partial measure, through group comparison method based in partial productivity index, and agregue measure, through Data Envelopment Analysis - DEA. The analysis between diferes dimensions of approach, diferente measure forms and about management inforination detail are effectuated through application of diferente models to one set of irrigate rice producers located on the southem coastline of Santa Catarina. There is evidence that the relative efficiency measure by DEA analysis is more precise and includes management assistance. Its allowd the integration and harmonisation between agro-economic-energetic aspects, considers multi-inputs and multi-outputs and factor substitutability effects, which provide major management information detail.
