Resumo
A disponibilidade e uso de energia é fator fundamental para o crescimento e desenvolvimento de qualquer país. Entretanto, é necessário que tal aspecto se processe de forma sustentável. Com isso, ganha importância a busca de fontes alternativas de energia, que atente para questões ambientais, sociais e econômicas. Neste contexto, a agroenergia tem papel de destaque, por ser uma fonte de energia renovável e limpa. No Brasil, realce se dá para a cana-de-açúcar, que desde os primórdios tem participação relevante e, a partir da década de 1970 passou a figurar como importante fonte de energia, substituindo em parte o uso do petróleo. A partir da década de 1980 e mais intensamente da década de 1990, com a aberturada economia brasileira, este setor vivenciou importantes transformações, passando a atuar em ambiente de livre mercado, o que exigiu dos agentes envolvidos maior competitividade e eficiência a fim de permanecer na atividade. As empresas participantes deste segmento adotaram estratégias que levaram à concentração da produção nas grandes usinas, fusões, verticalização da produção e exigências acerca do controle da quantidade e qualidade da matéria-prima a ser processada pela indústria. Participando desse cenário, existe a figura do produtor/fornecedor independente que também passa a ter que atuar de forma cada vez mais eficiente para atender à demanda da agroindústria e assim ter a sustentabilidade econômica. Neste sentido, este trabalho tem como objetivo estimar a eficiência econômica da produção de cana-de-açúcar dos produtores independentes do estado do Paraná, onde o setor é relevante para a economia local. Com a utilização do modelo DEA-BCC – Data Envelopment Analysis com retornos varáveis à escala orientado a inputs, foi estimada a eficiência econômica das unidades produtivas (designadas como DMUs - Decison Making Units)...
The availability and use of energy is essential to the growth and development of any country. However, it is necessary for this aspect to be carried out in a sustainable way. With this, the search for alternative energy sources, that watches out for environmental, social and economic issues is becoming more vital. In this context, agroenergy has an important role, as a source of renewable and clean energy. In Brazil, an emphasis is given to the sugar cane, which has a relevant participation from the beginning and, since the 1970s was renumbered as an important energy source, replacing in part the use of petroleum. From the 1980s and more intensively in the 1990s with the opening of the Brazilian economy, this sector has experienced major changes, starting to act on the free market, which required from those involved, greater competitiveness and efficiency in order to stay in activity. Companies participating in this segment have adopted strategies that led to concentration of production in large plants, mergers, vertical integration of production and requirements about the control of the quantity and quality of raw material to be processed by the industry. Participating in this scenario, there is the figure of the independent producer / vendor which has also to act more efficiently in order to meet the demand of the agricultural industry and thus have economic sustainability. So, this study aims to estimate the economic efficiency of production of sugar cane producers of the independent state of Parana, where the sector is relevant to the local economy. Using the DEA-BCC model - Data Envelopment Analysis with variable recurrences to scale oriented inputs, was estimated economic efficiency of production units (DMUs designated as - Decison Making Units). Results showed that most of the production units surveyed did not provide the maximum economic efficiency... (Complete abstract click electronic access below)
