南水北调中线干线工程运行成本分摊方法研究

Study on cost allocation method in operation of main line of South-to-North water diversion mid-route project

针对跨流域调水工程现有成本分摊方法,没有全面考虑各受水区水资源紧缺程度、水资源效益差异、经济社会发展水平等问题,基于受水区人均水资源量、万元GDP用水量、人均GDP,构建了跨流域调水工程运行成本分摊调整系数,并把此方法应用到南水北调中线一期干线工程的口门供水成本核算当中。结果表明,对分摊系数调整后,计算所得两部制水价更符合工程沿线各受水区的水资源自然情况与社会经济状况,有利于公平合理地分摊调水工程成本。

The existing cost allocation method of the inter-basin water diversion has still exist some problems,because some factors are not considered for each water receiving area, including the shortage degree of water resources, the benefit differences of water resources, the development level of economic society. Based on the water resources amount per capita, water consumption per ten thousand Yuan and GDP per capita, the cost allocation adjusting coefficient of the inter-basin water diversion operation is established, which has used in water supply cost accounting of the entrance for the first phase of the main line of South-to-North water diversion mid-route project. The result shows that the two part water price calculated by the adjusted allocation coefficients is more accord with the natural situation of water resources and society and economic situation for the each water receiving area along the project and is beneficial to the cost allocation of water diversion project with the fair and the rea sonably.
