浙江省工业用水的节水潜力及影响因素分析

Analysis on the water-saving potential and influence factors of industry in Zhejiang Province

对浙江省工业用水的资源配置效率进行了分析,在此基础上,以工业用水效率最高的地级市舟山市为参照,分析了浙江省其他地级市工业用水的节水潜力,以工业用水效率为因变量,对影响工业用水效率的因素进行回归分析,根据分析结果对浙江省工业用水效率的提高提出建议。结果表明:目前浙江省工业用水的资源配置偏离了效率原则,各地级市的工业用水有较大的节水潜力;对工业用水效率有显著影响的因素包括人均GDP、工业增值率、工业用水价格、外商及港澳台商投资规模以及人均教育费用等。各地级市应根据本地实际情况制定节水目标,采取相应政策措施提高该地区的工业用水效率,以保持经济、社会稳定健康地发展。

This paper analyzed the water resource distribution efficiency of industry in Zhejiang Province.Based on this analysis,taking the highest industry water utilization efficient prefecture-level city-Zhoushan City as reference,this paper analyzed the water-saving potential of other prefecture-level cities in Zhejiang Province;meanwhile,taking the industry water utilization efficiency as induced variable,a regression analysis was carried out on the influence factors on industry water utilization efficiency;finally,according to the analysis results,the suggestion about improving Zhejiang Province industry water utilization efficiency was brought forward.The results showed：currently the water resource distribution in Zhejiang Province industry departure from efficiency principle,and there was still high water-saving potential in other prefecture-level cities;the obvious influence factors on water-saving efficiency included per capita GDP,industry increase rate,industrial use water price,scale of foreign capital and capital from Hong Kong,Macao,and Taiwan,and per capita education cost.Every prefecture-level city should decide the water-saving goal according to the local situation and take proper measures to improve local industrial water utilization efficiency so as to keep the healthy development of society and economy.
