Abstract: Methods of sharing coefficient, mining loss, shadow pricing and alternative engineering are utilized to compute the benefits of water supply to Beijing through the Middle Route Project of South-to-North Water Diversion. The computing results show that a total amount of 31.18 billion CNY of water supply benefits has been generated since the operation of the water diversion project, 29.58 billion CNY of which is economic benefit, and the remaining 1.6 billion CNY is ecological-environment benefit; meanwhile, significant societal benefits have been created by the project after its operation. The computing results provide great reference for formulation of water diversion scheme and implementation of water resources optimum management.
