| 中文摘要:本文运用回归和收敛模型对全国，东部，中部，西部污染物排放强度的差异和收敛性进行了实证分析.研究结果表明：我国各地区的污染物排放强度在不同程度上都有所下降，其中以东部下降幅度最大，西部次之，中部最小；经济增长对污染物排放强度的降低起到积极作用，第二产业占GDP比重对污染物排放强度起到正相关作用；全国，东部，中部，和西部地区都不存在绝对β收敛现象，但均存在条件收敛，且中部收敛速度最快，东部收敛速度最慢. |

| 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 intensity has declined in varying degrees in each region,with the largest decline in the eastern region, followed by the western region, 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 absolute β convergence phenomenon, but the convergence condition has existed ,and the fastest convergence is in the central region and the slowest convergence. |
