【摘要】：本文以我国160个地级及以上城市作为研究样本,以PM2.5和PM10作为雾霾污染的衡量指标,构建空间Tobit模型对雾霾污染的环境库兹涅茨曲线假说(EKC)进行了实证检验。研究发现:我国城市雾霾污染呈现明显的空间集聚特征;在控制了经济规模等变量之后,雾霾污染与经济发展之间不支持倒"U"型的EKC假说,而是呈现线性递减关系,由此可见,我国的雾霾污染治理已经取得了阶段性的成效;在诸多控制变量中,经济规模、产业结构、人口密度对雾霾污染存在显著的正向影响,而经济密度的提高有助于降低雾霾污染,且雾霾污染与地理区位之间存在密切关联。尽管目前雾霾污染的治理取得了一定成效,但应清醒地认识到雾霾污染的治理是一个长期过程,在未来经济发展的过程中,要更加注重加快转变经济发展方式、调整优化经济结构。
[Abstract]:In this paper, 160 cities at or above the prefectural level in China are taken as the study samples, and PM2.5 and PM10 are taken as the measurement indexes of haze pollution. The environmental Kuznets curve hypothesis of haze pollution is empirically tested by constructing spatial Tobit model. It is found that the urban haze pollution in China has obvious spatial agglomeration characteristics, and after controlling the economic scale and other variables, The relationship between haze pollution and economic development does not support the inverted "U" type EKC hypothesis, but presents a linear decreasing relationship. It can be seen that China's haze pollution control has achieved periodic results. The industrial structure and population density have significant positive effects on haze pollution, and the increase of economic density can help to reduce haze pollution. And there is a close relationship between haze pollution and geographical location. Although the treatment of haze pollution has made some achievements at present, it should be soberly recognized that the treatment of haze pollution is a long-term process, and in the process of future economic development, it is necessary to realize that the treatment of haze pollution is a long-term process. More attention should be paid to speeding up the transformation of the mode of economic development and readjusting and optimizing the economic structure.
