摘要
论文从全过程管理的角度,利用对数平均的迪氏分解法(LMDI)将工业化学需氧量(COD)排放强度分解为源头防治、过程控制和末端治理三个部分。研究发现,2001-2010年中国工业COD排放强度降低主要归于源头防治,其次是末端治理,过程控制对工业COD排放强度降低的贡献较小,甚至为负。实证研究发现,环境技术转移对工业COD全过程管理的促进作用是最为显著的,而环境技术自主研发和工业污染源治理投资对全过程管理的作用并不大。因此,面对挑战严峻的中国环保问题,促进环境技术水平的提升,积极引进先进环境技术,强化环境规制,对实现从末端治理到全过程管理的转变是大有帮助的。
The industrial COD emission density is decomposed into source prevention, process control and end-of-pipe treatment using LMDI method from the view of whole process treatment. It was found that the reduction of industrial COD density was mainly relayed on source prevention, and the contribution of process control for whole process treatment is negative form 2001 to 2010 in China. In 11th FYP period,the effect of process control became bigger only in 5 provinces, and the contribution of process control decreased in 26 provinces. The effect of environmental technology on whole process treatment was investigated using provincial data from 2001 to 2010. It was found that, the environmental technolo- gy transfer promoted whole process treatment significantly, but the effect of environmental technology research and invest- ment in treatment of industrial pollution sources were not obvious. Thus, in order to fulfill the whole process treatment, we should upgrade the environmental technolo~ and strength the environmental remalation at the same time.
