城市群雾霾污染的空间分异及动态关联研究——基于京津冀城市群的实证分析

Spatial Differentiation and Dynamic Association of Haze Pollution in Urban Agglomeration: An Empirical Analysis Based on Beijing-Tianjin-Hebei Urban Agglomeration

污染治理联防联控是解决区域雾霾问题的重要手段,雾霾污染的城市联动和交互作用是雾霾区域协同治理的关键问题。本文运用探索性空间数据分析法和标准偏差椭圆方法,分析了京津冀雾霾污染的空间关联特征和空间重心转移轨迹,运用空间计量模型,测算了京津冀雾霾污染的空间溢出效应和驱动影响因素。结果表明:京津冀雾霾污染具有显著的空间集聚特征和空间异质性,雾霾污染的空间溢出效应明显,经济增长、城镇化发展、产业结构、人口密度等均对京津冀雾霾污染产生正向影响,外商直接投资对雾霾污染产生负向影响。本文从构建区域污染协同治理机制、区域产业资源的高效配置、城市空间管控等方面提出了城市群雾霾污染治理的对策建议。

Joint prevention and control is an important means to solve the haze problem,and urban interaction and interaction of haze pollution is a key issue for the coordinated management of haze pollution control.This paper applied the Exploratory Spatial Data Analysis method and Standard Deviation Ellipse method to analysis the spatial correlation characteristics and the transfer trajectory of spatial center of gravity of haze pollution in Beijing-Tianjin-Hebei urban agglomeration.The spatial spillover effect and driving factors of haze pollution in Beijing-Tianjin-Hebei were calculated by using spatial econometric model.The results showed that the haze pollution in Beijing-Tianjin-Hebei has significant spatial agglomeration characteristics and heterogeneity.The spatial spillover effect of haze pollution is obvious.Economic growth,urbanization,industrial structure and population density all have a positive impact on haze pollution in the local region,while FDI has a negative impact on haze pollution.Finally,the countermeasures and suggestions of haze pollution control in urban agglomerations were put forward from the aspects of building a mechanism of coordinated treatment of regional pollution,efficient allocation of regional industrial resources and urban space control.
