摘要
以吉林省为例,应用无残差完全分解模型,将工业污染产生量和排放量的变化分解为规模效应、空间结构效应和技术效应,分析清洁生产和末端治理不同产业生态化策略导向下的环境绩效,探索产业生态化发展改进方向。结果表明:清洁生产的控污效果在数量上大于末端治理的减排效果,产业生态化发展表现出以预防策略为主的特征。但是,环境目标主要通过清洁生产和末端治理来实现,产业生态化集聚发展滞后;清洁生产和末端治理之间的技术效应相关性较差,清洁生产主要通过技术进步来实现污染控制,而技术水平进步和规模的扩长都可以带来末端治理排污强度的降低;吉林省需要在源头预防策略指导下积极推动面向产品过程的污染控制转向面向系统过程的环境管理,促进产业生态系统的形成和发展。
Based on statistics of industrial pollutant yields and discharge quantity in Jilin Province, the non-residual decomposition model was applied to quantify the net amount of environmental benefits of clean production and end-pipe treatment respectively. Environ- mental performances of end-of-pipe and pollution prevention strategies were further analyzed to explore an appropriate way of improving regional industrial ecological transition. The results showed that industrial symbiosis did not exert a positive effect on environment improvement. Technical factor promoted environmental performance improvement in clean production, while both technical factor and scale factor did in end-pipe treatment. Clean production was superior to end-pipe treatment in pollution volume reduction, which implied that prevention strategy dominated over end-of-pipe strategy, but the improvement of clean production tended to slow down. It is necessary to construct a proper industrial ecological system for the realization of environmental goals.
