摘要
利用泰尔指数刻画福建省环境不平等的时空分布特征,通过LMDI模型和M-R模型从时间和空间的尺度上分析经济规模效应、产业结构效应和技术进步效应对福建省工业污染物排放差异的影响。结果表明:2011—2018年福建省工业废水的泰尔指数均超过0.24,工业固废的泰尔指数出现0.90的极大值。经济规模效应对福建省工业三废的减排始终起抑制作用,产业结构效应和技术进步效应交替出现促进与抑制作用。从时间尺度上看,对工业废水和工业固废物而言经济规模为累计正向贡献度最大的影响因素,对工业SO2排放影响最大的为产业结构效应。从空间尺度上看,对福建省工业废水、工业SO2排放量和工业固体废物产生量的区域差异贡献最大的分别为漳州市、福州市和龙岩市,三市减排空间巨大。
Thiel index is used to describe the spatial and temporal distribution characteristics of environmental inequality in Fujian Province.Logarithmic mean Divisia index and multi-Region model are used to analyze the impact of economic scale effect,industrial structure effect and technological progress effect on the difference of industrial pollutant emission in Fujian province from time and space scales.The results showed that the Thiel index of industrial wastewater in Fujian province exceeded 0.24 from 2011 to 2018,and the Thiel index of industrial solid waste reached a maximum of 0.90.The economic scale effect always restrains the emission reduction of three industrial wastes in Fujian Province.The industrial structure effect and the technological progress effect promote and restrain each other alternately.From the perspective of time scale,for industrial wastewater and industrial solid waste,economic scale is the most influential factor with the largest cumulative positive contribution,while industrial structure effect is the most influential factor for industrial SO2 emission.From the perspective of spatial scale,zhangzhou city,Fuzhou City and Longyan City have the largest contribution to the regional differences of industrial wastewater,industrial SO2 emissions and industrial solid waste production in Fujian Province,and the three cities have a huge space for emission reduction.
