Correlation analysis of haze governance influencing factors and regulation mechanism in Beijing-Tianjin-Hebei region

The degrees of association among haze and impact factors determine the correct judgment and grasp the decision-making path of haze governance. This paper uses the gray correlation method of system theory comparative analyze relevance factors of haze in Beijing-Tianjin-Hebei region. Higher absolute correlation degree of industrial structure and haze in Beijing province, and highest association of population and haze in Tianjin area and Hebei province; The relative degree of grey incidence between haze and population is highest in Beijing, the relative degree of financial development and haze in Tianjin area is highest, Hebei province urbanization rate is the highest; the comprehensive degree industry structure associated with haze is the highest in Beijing, Tianjin and Hebei province urbanization rate is the highest comprehensive correlation with haze. It can be seen that the economic development stage and economic development situation is different, Haze problems in Tianjin and Hebei have similar places so Beijing-Tianjin-Hebei regions need to take a coordinated haze governance policy. Finally, the paper discusses the haze governance strategies and suggestions for the future green development of Beijing-Tianjin-Hebei region on the basis of the results of this study aiming at the coordinated development of green transformation and coordination in Beijing-Tianjin-Hebei region, and promotes the innovation of urban agglomeration development theory and planning practice.
