Abstract

Este estudo teve como objectivos caracterizar e analisar a evolução, medir os níveis de eficiência técnica e relacionar esta com alguns atributos dos agricultores e das explorações, de uma amostra de explorações vitícolas pertencentes à região Alentejo. Os atributos considerados foram a dimensão física e económica, idade do produtor, natureza jurídica do produtor, tipo de posse da terra, irrigação, tipo de comercialização e especialização cultural e produtiva. A amostra analisada é composta por um painel de explorações, produtoras de uva para vinho para o período 2000-2005, pertencentes à Rede de Informação de Contabilidades Agrícolas, do Ministério da Agricultura, Desenvolvimento Rural e Pescas (MADRP). A caracterização e a análise da evolução das explorações vitícolas foram feitas com base num conjunto de indicadores técnicos e económicos. Para medir a eficiência, a metodologia utilizada foi paramétrica, utilizando uma fronteira de produção estocástica, em que foram testadas as características da distribuição utilizada para medir a eficiência, assim como a variabilidade desta ao longo do tempo. Para testar a relação entre a eficiência e os atributos dos produtores e das explorações utilizou-se o teste de análise de variância e o de Kruskall-Wallis. Os resultados mostraram que para estas explorações existe espaço para um aumento dos níveis de eficiência na utilização dos factores de produção e que a eficiência é variante em ordem ao tempo. Verificou-se um aumento da eficiência técnica com a dimensão económica e com o rendimento líquido das explorações, assim como com a empresarialização das mesmas.----------------------------------------------------------------Thi s study aims to characterize and to analyse the evolution of wine production, to measure the levels of technical efficiency, and to relate these with farmers and farms attributes. The attributes considered were the physical and economic size, the producer age, the farmer legal status, type of land ownership, land irrigation, type of commercialization and productive specialization. The sample used is composed of a panel of wine farms, producers of grapes for wine, for the period 2000-2005, enrolled in the European Farm Accounting System, belonging to the Alentejo region of Portugal. The characterization and the evolution analysis of the wine farms were done based on a set of technical and economic indicators. In order to measure the efficiency, the methodology utilized was the parametric one, making use of a stochastic production frontier. The characteristics of the utilized distribution to compute the efficiency were tested, as well as the efficiency variability with time. The relationship between the efficiency and the farms and farmers attributes was tested making use of analyses of variance and Kruskall-Wallis tests. The results showed that there are room to improve the levels of technical efficiency in input use and that efficiency is variant with time. The increase on technical efficiency with economic size and with farm net income was observed, as well as with farm entrepreneurship.
