摘要
利用天津市2003-2018年工业"三废"排放的相关数据,采用Tapio脱钩模型分析天津市经济增长与工业"三废"排放之间的弹性脱钩关系,并基于扩展的Kaya恒等式将工业"三废"排放的影响因素分解为排污强度、产业结构、经济规模、人口规模四个指标,结合LMDI分解法的加法模型对各个影响因素进行定量分析.结果发现:天津市近15年来,经济增长与工业废水排放之间主要表现为强脱钩状态;经济规模是工业"三废"排放的主要贡献因子,其对工业"三废"排放具有正向促进效应.
Abstract
Based on the relevant data of industrial"three wastes"emissions in Tianjin from 2003 to 2018,the Tapio decoupling model was used to analyze the elastic decoupling relationship between economic growth and industrial"three wastes"emissions of Tianjin,and the impacting factors of industrial"three wastes"emissions were decomposed into four indicators,namely,pollution intensity,industrial structure,economic scale and population size,based on the expanded Kaya identity,combined with the addition model of LMDI decomposition method,quantitative analysis was conducted on each influencing factor.The results showed that in recent 15 years,the relationship between economic growth and industrial wastewater discharge in Tianjin was mainly in a strong decoupling state;Economic scale was the main contribution factor of industrial"three wastes"emission,which had a positive promoting effect on industrial"three wastes"emission.
