浙江省工业用水效率与价格弹性测算研究

Study on the Measurement of Industrial Water Use Efficiency and Price Elasticity in Zhejiang

利用浙江省10个地区2010年到2013年工业行业经济数据,测算各地区工业用水效率和工业用水价格弹性,结果表明:浙江省各地区的工业用水效率差异明显,绝大多数地区的工业用水效率逐年提高并仍有提升空间;各地区的工业用水边际收益在9.708~66.748元/m^3之间,工业用水价格弹性在1.043~1.151之间波动,水价杠杆作用明显。研究结果可为深入推进浙江省"五水共治"、制定工业水价政策、提高工业用水效率、改革水资源管理体制提供参考。

The industrial economic data of 11 regions in Zhejiang Province from 2010 to 2013 were used in this paper to calculate industrial water use efficiency and industrial water price elasticity in various regions. Results show that the difference of industrial water use efficiency in different areas of Zhejiang Province is obvious; industrial water use efficiency in most areas is increasing year by year and there is still room for improvement. The marginal revenue of industrial water in each area is between 9. 708 yuan/m^3 and 66. 748 yuan/m3; the price elasticity of industrial water fluctuates between 1. 151 and 1. 043, and the leverage function of water price is obvious. The results can provide a reference for promoting ＂five kinds of water＂ governance in Zhejiang Province, formulating industrial water price policy, improving the efficiency of industrial water, and reforming water resource management system.
