基于水资源经济投入产出的重庆产业耗水研究

Research of industrial water consumption of Chongqing City based on water resources economic input- output

为分析重庆市各行业耗水情况,利用经济学中的投入产出原理,将重庆市2007年的产业耗水量纳入投入产出表中,建立了水资源经济投入产出模型,计算了各个产业的耗水系数,并进行产业间用水效益比较。结果表明,重庆各产业部门间接耗水量隐蔽性较高,不易察觉;产业部门不同,耗水系数占其相应的总耗水比例相差很大;投入产出表可以用来研究产业经济发展和耗水量的关系。分析结果可为重庆产业结构的调整和可持续发展提供一定参考。

To analyze the water consumption of various industries in Chongqing City, the input - output model of water resources economy is established based on input - output theory in economics by bringing the industrial water consumption of Chongqing City in 2007 into the input - output table. The water consumption coefficients of various industries are calculated, and the water resources utilization benefits are compared. The result shows that the indirect water consumption of each industrial department is highly concealed, which is difficult to be perceived; the proportion of the water consumption coefficients of each industry in total water consumption is different ; the input - output table can be used to study the relationship between the industrial economic development and water consumption. The analysis results lay a scientific foundation for the industrial structure adjustment and sustainable development of Chongqing City.
