【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。
[Abstract]:Based on the input and removal data of industrial water pollutants from 2005 to 2013, the efficiency of water pollution control in 38 industrial sectors in China was calculated for the first time by using the pollution equivalent method and DEA model. The results show that the overall treatment efficiency is low, the input and removal of water pollutants in different departments are different, the efficiency of water pollution treatment is different, and the DEA is relatively effective in 18 industrial sectors. However, some of the major industrial sectors have a large discharge of water pollutants, exacerbating environmental pollution in the discharge areas, and DEA is ineffective in water pollution control in 20 industrial sectors. Its pollution to the environment is also increasing; the efficiency of water pollution treatment in 15 industrial sectors is declining. The efficiency of water pollution control mainly depends on the improvement of technical efficiency, but the support of technological innovation is weak. Finally, according to the characteristics of various departments, countermeasures and suggestions are put forward.
