贵州省国民经济水资源消耗的投入产出分析

目的]研究贵州省国民经济各产业部门的用水量,找到提高水资源用水效率的方法。方法]在贵州省2012年投入产出表的基础上,运用水资源投入产出法将其应用范围扩展到产业耗水量领域,对贵州省国民经济用水进行定量分析,将传统的投入产出表与国民经济各部门的取耗水相结合,建立了贵州省2012年的水资源投入产出表与产业部门用水模型,并分析各个产业部门的直接用水系数、完全用水系数、间接用水系数与用水系数等相关参数。结果]目前贵州省第二产业部门与第三产业部门为主要用水需求部门;除农业部门外,其他部门都具有不同程度的用水隐蔽性,部门用水乘数很高,未来用水潜力大。结论]应大力发展现代农业,提高农业节水量;加强第二产业各个部门的协作,着重发展绿色循环工业经济;跟进贵州省"大数据"发展步伐,增加高新技术产业与服务业的比例。

Input-Output Analysis of Water Consumption in National Economy of Guizhou Province

Objective] To study the water consumption of industrial sectors of the national economy in Guizhou Province and find ways to improve the efficiency of water resources.Methods] Based on the input-output table of Guizhou Province in 2012, this paper extended the scope of its application to the field of industrial water consumption by means of water resources input-output method, and made a quantitative analysis of the national economic water use in Guizhou Province. The traditional input-output table was combined with the consumption water phase of each department of national economy, and the water resources input-output table and the industrial water use model of Guizhou Province in 2012 was established. The direct water use coefficient, the coefficient of total water use and the coefficient of indirect water use were analyzed.Results] The second industry department and third industry department were the main water demand departments in Guizhou Province. In addition to agriculture department, other departments also have concealment in water use to some extent. Water use multiplier of each department was high, and the potential improvement for future water use is large.Conclusion] We should energetically develop modern agriculture and increase the water saving capacity of agriculture, and strengthen the cooperation among all sectors of the second industry, and focus on the development of green recycling industry economy. Follow up the development of "big data" in Guizhou Province and increase the proportion of high-tech industry and service industry.
