从经济观点出发,无论是现有供水工程或待建供水工程,都应进行供水成本计算。但究竟如何计算呢?水利工程的产品(供水)成本计算又不同于一般产品的成本计算,有许多问题值得研究。目前,许多同志提出了供水成本的计算方法,纵观这些方法,有一个问题值得注意,即把效益分析的方法用于供水成本计算上,这是不合理的,应予以澄清。本文提出了水利工程供水成本计算的方法,并结合论述了笔者对成本计算与经济效益计算不能混淆的新观点。
From the economic point of view, whether the existing water supply project or the water supply project to be built, the cost of water supply should be calculated. However, how is it calculated? The calculation of the product (water supply) cost of a water conservancy project is different from the cost calculation of a general product. There are many problems worth studying. At present, many comrades have proposed calculation methods for water supply costs. Looking at these methods, one problem is worth noting. That is, the method of benefit analysis is used to calculate the cost of water supply. This is unreasonable and should be clarified. This paper proposes a method for the calculation of water supply costs for water conservancy projects, and combines the author’s new ideas that cannot be confused with cost calculations and economic benefits calculations.
