摘要
基于2005~2013年工业水污染物治理投入与除去数据,利用污染当量法和DEA模型,首次计算了中国38个工业部门水污染的治理效率。结果表明：总体治理效率较低,不同部门的水污染物治理的投入和去除状况、水污染治理效率差异明显;18个工业部门具有DEA相对有效,但其中一些重要工业部门的水污染物排放量大,加重了排放区域的环境污染;20个工业部门水污染治理存在DEA无效,其对环境的污染亦在加剧;15个工业部门的水污染治理效率在不断下降。主要产业部门的水污染治理效率主要依靠技术效率改善来支持,而技术创新的支持较弱。最后,针对各部门特点提出了对策建议。
Using the annual data of water pollution treatment from 2005 to 2013, the efficiencies of water pollution treatment in 38 industrial sectors are calculated by DEA-malmquist model. The results show that the water pollution treatment efficiencies of different sectors are different. There are 18 sectors having DEA efficiency, and 20 sectors having no DEA efficiency. Among them, the treatment efficiency of 15 sectors decreased in the study period. The key industrial sectors with DEA efficiency or without DEA efficiency have a large quantity of water pollutant emissions. They are exasperating water environment. The treatment efficiencies of most industrial sectors are mainly from the improvement of technological efficiency, and the contributions from its technological advancement are small. At last some conclusions are drawn.
