投资费用分摊对于分清调水工程各受益地区之间、部门之间的经济责任大小以及水价测算和定价等工作具有 重要作用。提出基于过程和产生机制的调水工程投资费用分摊与两部制水价测算方法, 旨在在分摊时反映水价要 素的变化过程以及费用产生机制。在阐述投资分摊和费用分摊的原则、方法和具体步骤的同时, 分析了两部制水价 与单一制水价之间的关系以及供水量、还贷等要素变化过程对水价的影响。最后以产芝水库调水工程为例, 研究了 向多地区供水的、具有多种费用产生机制和要素变化过程的调水工程投资费用分摊与两部制水价测算方法。

Investment and co st allocation play s a crucial ro le in disting uishing the eco nomic r espo nsibilities of a w ater tr ansfer pr oject amo ng different reg ions and depart ments, and water pr ice calculatio n and determination. In this paper, a new investment and cost allocatio n and two2par t w ater price method was presented to reflect the var iatio n pr ocess of w ater price elements and generatio n mechanism of supply ing cost. The principles, methods, and implement steps of investment allocatio n and co st alloca2 tion w ere presented.

Finally, a case study in r egar d to the com2 plex pro cesses and generation mechanism of supply ing co st o f Chanzhi water transfer pro ject was presented.
