江西虚拟水消费与贸易研究——基于投入产出分析

CONSUMPTION AND TRADE OF VIRTUAL WATER IN JIANGXI BASED ON INPUT-OUTPUT ANALYSIS

分析各产业虚拟水消费与贸易状况对建立江西特色的水资源利用战略具有重要意义。以2007年投入产出表为基础,并结合水资源公报、中国环境年鉴等统计资料,对2007年江西省各经济部门虚拟水消费与贸易进行了投入产出分析:计算出各产业部门的用水量及相应的用水系数,并分析了各部门之间用水相关关系;编制了2007年各部门虚拟水转移矩阵。江西省水资源消耗较大的部门为种植业、畜牧业部门,水资源出口结构不够合理,需优化农、畜产品输出结构;大力发展第二产业,同时设定防止水质型缺水的政策保障;适度发展耗水量大的第三产业。

Analysis of virtual water consumption and trade of industries is of great significance in building distinctive water use strategies in Jiangxi Province.Based on Input-output tables in 2007,combined with Jiangxi Water Bulletin,China Environment Yearbook and other statistical data,this paper made a input-output analysis on the consumption and trade of virtual water in various economic sectors in 2007 in Jiangxi Province,calculating the water consumption and corresponding coefficient of water using by industrial sectors,and analyzing the relationship between sectors of water;formulating 2007 virtual water transfer matrix of various departments.The main conclusions and policy recommendations lie below：industry sector of higher water consumption is crop sector and livestock sector;the export structure of water resources is unreasonable,and it is necessary to optimize the output structure of agricultural and livestock;to develop the secondary industry,while setting policies to prevent water shortage from water deterioration;to developing the tertiary industry of high water consumption moderately.
