对不断上涨的水和污水处理价格的关注，重新引起了人们对衡量和评估水务公司业绩的兴趣。效率分析可以作为定价决策的基础。本文考察了所有权结构和公司规模对爱沙尼亚水务公司效率的影响，并通过公司治理和自然垄断理论的视角评估了经验效率差距。为了评估效率以及所有权和公司规模对效率的影响，我们使用了数据包络分析和截断回归与最大似然估计以及方差分析检验。研究样本包括43家自来水公司，为爱沙尼亚68%以上的人口提供服务。该研究的一个主要发现表明，所有权结构不影响爱沙尼亚水务公司的效率，而效率确实随着公司规模的增加而增加：大型水务公司的表现优于小型水务公司。另一个结论是，爱沙尼亚的水部门过于分散。
Concerns regarding rising water and sewerage prices have generated a renewed interest in measuring and assessing water utility performance. An efficiency analysis can serve as a basis for price setting decisions. This article examines the influence of ownership structure and corporate size on the efficiency of Estonian water companies, and assesses the empirical efficiency gaps through the lens of corporate governance and natural monopoly theories. To assess efficiency and the influence of ownership and corporate size on efficiency, we use a Data Envelopment Analysis and truncated regression with maximum likelihood estimation as well as an ANOVA test. The study sample consists of 43 water utilities, serving more than 68% of the Estonian population. One main finding of the study reveals that ownership structure does not affect the efficiency of Estonian water utilities, while efficiency does increase with corporate size: large water utilities outperform small utilities. An additional conclusion is that the Estonian water sector is too fragmented.
