经济联系、产业结构与“标杆协同”减排效应

Economic Contact,Industrial Structure,and Benchmark Synergistic Effect in Emission Reduction

将经济发展水平高、排污水平低的地区视作被学习的"标杆",那么高排污地区与"标杆"地区如果能够在污染物减排上出现方向一致、幅度相近的变化,则认为区际间产生了"标杆协同"减排效应。本文首先从理论层面分析了区际经济联系、产业结构与"标杆协同"减排效应之间的关系,并以京津冀地区的烟(粉)尘减排为对象进行了三者关系的实证研究。结果发现,京津冀地区"标杆协同"减排效应与经济联系强度呈现单调递增变化,与产业同构化程度呈现"倒U型"关系,同时"标杆协同"减排效应自身会存在"惯性阻力",对后期协同效果产生显著的负向影响。因此,通过保持紧密的经济联系和适当的产业同构关系能够在区际间产生"标杆协同"减排效应,进而有利于区域整体环境质量的改善。

The benchmark synergistic effect in emission reduction refers to a consistent-direction and similar-size change between the high emission region and benchmark region, which has a high economic development and low discharge level. The article analyzes the relation among inter- regional economic contact, industrial structure and benchmark synergistic effect from the theoretical view. For verifying the relation among the variables, an empirical research is developed using soot ＆ dust discharged data in Jing- Jin- Ji area. The results prove that benchmark synergistic effect is monotonic increase to the economic contact and inverted U- curve to the industrial isomorphism degree in the area. Meanwhile, the effect has an inertia resistance, which will make a negative impact to the later synergy degree. Therefore, the close economic contact and proper industrial isomorphism can create inter-regional benchmark synergistic effect in emission reduction, which will improve the environmental clualitv of whole area.
