【摘要】 基于劳动价值论以及边际效用价值论，提出了价值的边际劳动价值决定论以及多用途条件下水经济价值的评估理论和方法，认为水经济价值取决于供需平衡时各种用途用水效益的最小值或供水成本的最大值。基于该理论和方法，对北京市原水经济价值进行了评估，结果表明，北京市的水经济价值是由效益低的农业用水界定，北京市农业用水效益的估计值更接近水的价值。结合可视为北京市边际供水成本的南水北调水价，2020年北京市原水经济价值应在2.33～4.82元/m~3之间。更多还原

【Abstract】 Based on labor theory of value and marginal utilitytheory of value, this paper proposed the marginal labor value determinism of value and established the theory and method for evaluating the economic value of multi-purpose water.The economic value of water should depend on the minimum value of water benefits for various use or the maximum value of water cost at the balance of supply and demand. Based on this theory, the economic value of raw water in Beijing was assessed. The results show that the economic value of water in Beijing is defined by agricultural water, and the estimated value of agricultural water benefit in Beijing is closer to the value of water. Combined with the South-to-North water price, which can be regarded as the marginal cost of water supply in Beijing, the economic value of raw water in Beijing in 2020 should be between 2.33 and 4.82 RMB Yuan per cubic meter.更多还原
