Research On The Water Pricing Model For Transbasion Diversion Project And Its Application

According to the up-to-date full cost pricing theory, water supply price is composed of triple costs, which include resource cost, environment cost, engineering cost, profit and tax. In a transbasin diversion project, the catchment area and the intake area often belong to different administration regions. Therefore, their finance, revenue and investment system are relatively independent from each other, which means that the research on the full cost pricing model can be carried out. Combined with the characteristics of transbasion diversion project, my article research in meanings calculate methords for all parts of triple costs of full cost pricing.Resource cost, namely the water rights price, is the economic extemalization of national ownership for water. It includes natural water resource price and compensation for the investment in the prophase and actuality of water resource management, etc. Natural water price can be estimated indirectly by current international empirical method. The estimated value will reflect the shortage degree of local water resource, the exploitation difficulty of water resource, the level of local economic development, and so on.Environment cost is the economic compensation for handling cost of society and water environment used to make water meet a certain water quality standard. The cost is made up of water environment recovery cost and compensation for the limit to economic development in catchment area.Engineering cost means the manufacture cost of water commodity and its property right income. It comprises the depredation expense of fixed assets, engineering maintenance expense and engineering operational guidance cost. Engineering cost in a transbasin diversion project must include two parts. They are water source engineering and direct engineering.By the foundation of the definition about two-part water price, according to the features and meanings of a cost, it may be brought into capacity water price or measurement water price. These two kinds of water price constitute two-part water price. The application of two-part water price will be propitious to the appropriate allotment of water resource.At last, the water pricing model is utilized in the Dong-shen water supply project. The theoretical water price is 4.370 Yuan per cubic meter. In response to two-part water price system, the capacity water price is 2.109 Yuan per cubic meter, and the measurement water price is 2.322 Yuan per cubic meter.
