ABSTRACT Wastewater services involve complex technical and environmental processes. Conventional performance assessments often disregard the service quality aspects of the sector. This article applies an advanced semi-parametric modelling framework based on data envelopment analysis to measure the economic efficiency of wastewater service provision in Australia whilst accounting for service quality. We find that the volume and type of sewer treatment, the number of treatment plants, and population density are among the exogenous factors that influence the operational efficiency of wastewater utilities. Inclusion of service quality parameters can make a significant difference in efficiency evaluations.

评估废水服务的运营效率，同时考虑数据的不确定性和服务质量：半参数方法

摘要 废水服务涉及复杂的技术和环境过程。传统的绩效评估往往忽视该部门的服务质量方面。本文应用基于数据包络分析的先进半参数建模框架来衡量澳大利亚污水服务提供的经济效率，同时考虑服务质量。我们发现下水道处理的数量和类型、处理厂的数量和人口密度是影响污水处理设施运营效率的外生因素。包含服务质量参数可以在效率评估中产生显着差异。
