本文更新了水公用事业基准研究的文献在世界范围内进行，重点是规模和范围经济。使用元回归分析，研究调查哪些变量从发表的研究影响这些经济。我们的分析得出了几个结论。结果表明，有一个更高的概率发现规模和范围不经济的大型公用事业，但是，只有规模经济的结果是显着的。规模和范围不经济更可能出现在公有公用事业中，而不是在所有权主要为私人所有的情况下;正如预期的那样，多公用事业更可能具有规模和范围经济。
This paper updates the literature on water utility benchmarking studies carried out worldwide, focusing on scale and scope economies. Using meta-regression analysis, the study investigates which variables from published studies influence these economies. Our analysis led to several conclusions. The results indicate that there is a higher probability of finding diseconomies of scale and scope in large utilities; however, only the results for scale economies are significant. Diseconomies of scale and scope are more likely to be found in publicly-owned utilities than when the ownership is mostly private; as would be expected, multi-utilities are more likely to have scale and scope economies.
