中国污染物排放强度及其收敛性的区域差异研究
Analysis on the Regional Differences in Pollutant Emission Intensity and Spatial Convergence in China
摘要
Abstract
This paper used the regression and convergence model to analyze the regional differences in pollutant emission intensity and spatial convergence among the eastern,central and western region.The results show that pollutant emission in-tensity has declined in varying degrees in each region,with the largest decline in the eastern region,followed by the western re-gion,and the central region being the minimum;economic growth plays a positive role to reduce emissions intensity,and the secondary industry to GDP has played a positive role to pollutants emission intensity;the eastern,central and western regions do not exist absoluteβconvergence phenomenon,but the convergence condition has existed ,and the fastest convergence is in the central region and the slowest convergence.关键词
