城市工业环境绩效的驱动效应分析——以徐州市为例

Analysis of Driving Effects on Industrial Environmental Performance:A Case Study of Xuzhou

以徐州市为例,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、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导向下的工业环境绩效,探索城市工业生态化转型方向。结果表明:末端治理的减排效果在数量上大于清洁生产的控污效果,产业绿色化发展表现出末端治理的导向特征,但产业绿色化目标的实现依然是末端治理与清洁生产共同作用的结果。清洁生产控制污染主要通过产业结构调整优化来实现,而技术进步和结构调整优化都可以提高末端治理减排效果。加强清洁生产技术和工艺的推广应用是徐州市推动产业绿色化转型的重要策略选择。

A non-residual complete decomposition model was applied to evaluate contributions of three factors,scale effect,structure effect,technical effect,to the change of the amounts of both industrial pollutant production and emission in Xuzhou.This paper analyzed environmental performances of the clean production and the end-of-pipe treatment to explore an appropriate way of the future industrial ecological transition.The results showed that the end of-pipe treatment was superior to the clean production in the pollution reduction,which implied that the end-of-pipe strategy should dominate the future green industry.However,a combination of the clean production and the end-of-pipe treatment is also needed to achieve the goal of the green industry.The adjustment of industrial structure promoted the environmental performance in the clean production,while technical improvement and change of industrial structure is useful to reduce the emission by using the end-of-pipe treatment.It is necessary to strengthen clean production technologies and make full use of them to improve the industrial ecological transition in Xuzhou.
