摘要

摘要本文旨在评估巴西公共灌溉项目的效率。采用了数据包络分析(DEA)模型，该模型使用了一组有限的重要变量，并适应了该国现有公共灌溉项目的具体特点。然后对有效灌溉项目进行多元回归分析，以估计DEA模型中未考虑的其他投入。结果表明，在研究的34个公共项目中，有15个项目达到了技术效率得分、纯效率得分和规模效率得分。这项工作为灌溉管理的文献和决策者的实际意义带来了一些新的贡献。值得注意的是，这项研究的结果可能有助于更好地了解公共灌溉的总体效率及其最具决定性的因素。

Efficiency and its determinants in the public irrigation projects of Brazil

Abstract This paper aims to assess efficiency in the public irrigation projects of Brazil. A Data Envelopment Analysis (DEA) model using a limited set of significant variables and adapted to the specific characteristics of existing public irrigation projects in the country was used. Then a Multiple Regression Analysis was performed to efficient irrigation projects to estimate other inputs that did not have been considered in the DEA model. The results indicate that 15 public projects out of the 34 studied, reached the technical efficiency score, as well as pure efficiency and scale efficiency. The work brings several new contributions to the literature on irrigation management and practical implications for decision makers. It is noteworthy that the results of the study can be useful for a better understanding of the general efficiency of public irrigation and what are its most determining factors.
