摘要

基于投入产出分析法

以甘肃省2007年行业经济及用水数据为基础

构建了地区水资源投入产出表。通过对甘肃省行业用水系数、用水乘数、用水量等指标的分析

研究了甘肃省各行业对经济系统的水资源消耗间接拉动效应。在此基础上进一步研究了经济系统内部行业间虚拟水的转移

分析了经济系统内部虚拟水的流向

并通过计算甘肃省虚拟水的进出口量对经济系统间虚拟水的流向进行了分析。分析结果表明

种植业用水系数、用水量在该省行业中处于最高

对经济系统水资源的间接拉动影响较小

是主要的虚拟水输出行业。其中一部分虚拟水流向制造业

经由制造业流向建筑业与服务业等行业

另一部分流向省外。在构建节水型经济系统的过程中

由于行业间水资源消耗的关联性

考虑到其他行业对种植业的间接拉动

在采取缩小种植业规模提高种植业节水效率及调整区域产业结构的情况下

应将减少消费端的物质消费因素考虑进去。

Abstract

The input-output analysis method was applied to construct a water resource Input-output table on the basis of the data collected in 2007 in Gansu Province.This study focused on the impacts of water resources on the industrial and economic development of Gansu Province by analyzing water use rate

water multiplier and water consumption.Furthermore

virtual water transfer between industry and economy system virtual water transfer among different industries

and the flow direction of virtual water in economic system were addressed.The results indicated that agriculture(plantation for example) had the highest water use rate and total volume but had little contribution to the indirect boost of economic system by water resource.Some water resources virtually flew to manufacturing and then subsequently to construction and service industry.In addition

considerably amount of water flew to other provinces.During the process of promoting the water saving economic system

we should reduce the scale of agricultural production and improve the efficiency of agricultural water use.We should also readjust industrial structure

considering the relevance of water resource consuming between the industries.In addition

we should take into account the factors reducing the consumption of goods by the clients.
