【摘要】：城镇化率的提升是否会加剧雾霾污染?在当前国家大力推进新型城镇化建设的背景下,对于该问题的科学解答显得尤为必要。利用空气质量指数(AQI)对雾霾污染进行测度,构建空间联立方程研究,城镇化率和雾霾污染的交互关系及其空间效应,采用广义空间三阶段最小二乘法(GS3SLS)进行整体估计,结果表明,城镇化率的提升对雾霾污染有显著的负向影响,雾霾污染对城镇化率的提升具有显著的抑制作用,二者皆存在显著的空间溢出效应,周边地区的城镇化率和雾霾污染对本地区会产生负向影响。分组研究进一步验证了随着城镇化率的提升雾霾污染逐步减轻这一结论,组2(城镇化率≥60.8%)的估计结果明显比组1(城镇化率60.8%)要显著,揭示了城镇化率的提升对雾霾污染呈负向影响这一趋势随着城镇化率的提高而愈发显著。研究还发现,随着城镇化率的提升,经济发展水平和雾霾污染之间存在"N型曲线"关系,这对当前城镇化率较高的地区是一个警示。
[Abstract]:Will the increase of urbanization rate aggravate haze pollution? Under the background of promoting the construction of new-type urbanization, the scientific solution to this question is particularly necessary. The air quality index (AQI) is used to measure the haze pollution, the spatial simultaneous equation is constructed, the interaction between urbanization rate and haze pollution and its spatial effect are studied, and the generalized spatial three-stage least square method is used to estimate the whole. The results showed that the increase of urbanization rate had a significant negative effect on haze pollution, haze pollution had a significant inhibitory effect on urbanization rate, and both of them had significant spatial spillover effects. The urbanization rate and haze pollution in the surrounding areas will have a negative impact on the region. The group study further verified the conclusion that haze pollution gradually decreased with the increase of urbanization rate. The estimated results of group 2 (urbanization rate 鈮，
