摘　　要：从经济学角度考虑,水资源供需矛盾的加剧提高了水资源的利用效益。用水量决定用水效益,用水效益制约水量在产业间的分配。在分析河南省及各地市2003—2013年用水演变的基础上,将水资源作为生产要素之一,利用C-D函数计算河南省2003—2013年农业、工业和生活用水边际效益。结果表明,河南省以生态用水量增长最为显著,各产业用水边际效益逐年递增,农业、工业、生活多年平均用水边际效益分别为2.35、130.96、9.51元/m3,工业用水边际效益高于农业和生活。河南省用水边际效益的增加与现行水价的偏低形成鲜明对比,计算结果对河南省水资源优化利用和水价改革具有一定的指导和参考意义。Considering from the economic angle,the contradiction of water supply and demand promotes the benefits of water utilization.Water consumption determines water utilization benefits,and water benefits restrict water consumption.On the basis of water consumption evolution from 2003 to 2013,the marginal benefits of agricultural,industrial and domestic water consumption in Henan province were calculated.The results showed that the ecological usage increased remarkable,and the marginal benefits increased year by year.The average marginal benefits of agricultural,industrial and domestic water consumption were 2.35,130.96 and 9.51$/m3,respectively.The continuously increasing marginal benefits form a sharp contrast to current low water price.The results have some guidance and reference to water resource optimal utilization and water price innovation.
