针对资源环境经济评价中存在的资源耗减成本难以估价的问题,基于水资源环境经济核算研究,从水资源的商品流通性出发,提出以影子价格评价水资源价值的思路。分析了水资源耗减的基本概念,并以水资源耗减量计算为基础,提出了水资源耗减成本计算方法。最后对全国以及一级流域进行了估算和分析,结果表明:2005年我国水资源耗减成本达到了1647亿元,占总GDP的0.91%;在各一级流域中,海河流域水资源耗减成本最高,达到了768.6亿元,约占其GDP的2.92%,这客观反映出海河流域水资源短缺问题。水资源耗减成本方法可以完善综合环境经济核算中价值量核算的研究。
Aiming at the problem that resource depletion cost is hard to value in resource economic evaluation, based on the study of water resource environmental economic accounting, this paper proposes the idea of using shadow price to evaluate water resource value from the perspective of commodity liquidity of water resources. The basic concept of water resource depletion is analyzed. Based on the calculation of water resource depletion, the calculation method of water resource depletion cost is proposed. Finally, the national and first-level river basins are estimated and analyzed. The results show that in 2005, the cost of water resources reduction in China reached 164.7 billion yuan, accounting for 0.91% of the total GDP. In the first-class river basins, the water resources in the Haihe River Basin were reduced The highest cost, reaching 76.86 billion yuan, accounting for 2.92% of its GDP, which objectively reflects the water shortage in the Haihe River Basin. The method of water resource cost reduction can improve the study of value accounting in comprehensive environmental economic accounting.
