两部制水价研究——以一项长距离输水工程为例

A study on two part water pricing system:a case study on a long distance water diversion project

文章以一项长达213 km的输水工程项目为研究对象和财务主体,建立动态财务分析模型,在工程水价测算的基础上,对基本水价和计量水价相结合的两部制水价设计进行了准确计算,对比分析了两部制水价与单一制水价财务可持续性的显著差异。该输水工程采用两部制水价运行初期资金缺口较单一制水价大幅降低,财务生存能力显著增强,说明两部制水价较好地解决了运行初期未满负荷运行,售水收入较低,运行维护和还贷资金不足的问题,以及运行后期获得适当利润,满足其作为非农业供水工程的政策收益要求。

Taking a 213 km water diversion project as the research object and financial entity,this artucke establishes a dynamic financial analysis model,and accurately calculates the two-part water pricing design that combines basic water prices and metered water prices based on the calculation of engineering water prices and compares the significant differences in financial sustainability between two-part water pricing and single water pricing.The water diversion project adopts a two part water pricing system,which significantly reduces the initial funding gap compared to a single water pricing system,and significantly enhances its financial survival ability.This indicates that the two part water pricing system effectively solves the problems of under load operation,low water sales revenue,insufficient funds for operation,maintenance,and loan repayment in the early stage of operation,as well as obtaining appropriate profits in the later stage of operation,meeting its policy income requirements as a non-agricultural water supply project.
