南水北调工程受水区经济效应评价——以河南省为例

投入产出分析方法是分析水资源使用效率和使用效益的重要方法。本文在计算各产业部门的用水投入系数和用水产出系数的基础上,提出了估算调水经济效应的方法,并对南水北调中线工程受水区——河南省的调水经济效应作定量评价。评价结果表明:河南省不同产业部门的用水产出效益差异比较大,用水产出效益较高的部门分别为商业、交通运输仓储业、建筑业、非金属矿物制品业、食品制造及烟草加工业。在南水北调中线工程调水运营期,调水为河南省带来的直接经济效益为157.83亿元,对河南省整个经济系统的GDP贡献值达到341.79亿元,其中对GDP贡献率比较大的是用水产出效益较高的部门。

Evaluation on the Economic Effects of the Water Imported Areas in the South-to-North Water Transfer Project - Taking Henan Province for Example

The input-output analysis is a major method for analyzing the efficiency and benefit of the utilization of water resources.Based on calculating the coefficients of input and output of water using in various industrial sectors of national economy,this paper puts forward a method for evaluating the economic effects of water transfer and analyzes the direct and indirect economic effects by using this method,selecting Henan Province as a representative region of water imported areas in the South-to-North Water Transfer Project.The evaluation indicates that the output benefit is quite different for the different sectors of Henan Province.The high benefit sectors are commerce,transportation and storage,construction,nonmetal mineral products,food production and tobacco processing.During the operating terms of the project,157.83 billion yuan of direct benefit will be contributed to Henan Province,and the contribution value to the GDP of Henan Province may be 341.79 billion yuan.It is the high benefit sectors that make the higher contribution rate to GDP.
