摘要
本文以海河流域8个案例区为例,比较了残值法、扣除非水成本法和效益分摊系数法3种分析计算行业水经济价值的方法。结果认为效益分摊系数法相对合理,适用于计算各行业水经济价值,扣除非水成本法仅适用于计算种植业水经济价值,在计算第二、三产业行业水经济价值时会出现失真。
A comparison of three methods for calculating economic value of water is carried out. The methods include residual method, non-water cost deduction method and benefit sharing coefficient method. The calculation results of eight case studies for Haihe River basin are to be compared. The result shows that the benefit sharing coefficient method is the most practical which is suitable to the calculation of water economic value for all industry sectors and the calculation result is approximately equal to that of residual method. The non-water cost deduction method is only suitable to the calculation for water economic value of crop planting since distortion will occur when calculating the values of secondary and tertiary sectors.
