Abstract:
Based on the cost composition and joint cost characteristics of the Middle Route of South-to-North Water Diversion Project, the cost allocation method was selected according to the features of joint cost. On the basis of two-part water price mechanism composed of the basic water price and measured water price, the water price calculation method for the entrance of main line was designed with price slope from front to back, and two-part water price for each province along the Middle Route was calculated. The sensitivity analysis was applied to characterize the main factors of water price. The results showed that the two-part water price and its determination methods are feasible and the calculated water price is within the scope of consumers’ bearing capability. Water price is greatly affected by water supply. The two-part water price mechanism can provide references for the establishment and adjustment of water price in the Middle Route of South-to-North Water Diversion Project.
