京津冀地区产业结构和用水结构变动关系

水资源对社会经济发展至关重要。研究产业结构和用水结构变动关系,揭示经济发展与水资源利用的内在联系,对缺水地区水资源进行合理配置,特别是对处于特殊战略地位的京津冀地区具有重要意义。利用2002-2016年北京市、天津市、河北省产业结构及用水结构数据,采用产业结构与用水结构协调度等指标对京津冀地区产业结构与用水结构的演变趋势进行了评价,并基于成分数据的线性回归方法建立了京津冀地区产业结构与用水结构的线性回归模型,进一步研究产业结构与用水结构的相关关系,结果表明:北京市第三产业增加值比重与第三产业用水比重高度相关,河北省第二产业增加值比重与第二产业用水比重之间也表现出较强的相关性。

The relationship between industrial structure and water consumption structure in Beijing Tianjin Hebei Regio

Water resources are of vital importance to social and economic development.The relationship between industrial structure and water consumed structure,revealing the link between economic development and water resources utilization and allocating water resources rationally,is of great significance to the Beijing Tianjin Hebei region from strategic point of view.In this paper,we used the industrial structure and water consumed structure data from Beijing,Tianjin and Hebei Province during 2002 to 2016,and the indicators,such as,the coordination degree of industrial structure and water consumed structure,to investigate the evolution trends of industrial structure and water consumed structure in Beijing Tianjin Hebei region.The linear regression method based on the component data was also used to establish a linear regression model between industrial structure and water consumption structure.The results showed that the proportion of the added value of the tertiary industry in Beijing was highly related to the proportion of water consumption of the tertiary industry.The proportion of the added value of the secondary industry in Hebei Province and the proportion of water consumed in the secondary industry also showed a strong correlation.
