In order to study the spatiotemporal characteristics of PM2.5 and O3 concentrations and health risks in the Beijing-Tianjin-Hebei region and their cooperative control regions, this study constructed a Beijing-Tianjin-Hebei composite pollution correlation network by quantifying the Composite Pollution Health Index, taking the cities as the nodes and the similarity of the composite pollution among the cities as the weights; and based on the Girvan-Newman community detection method, the Beijing-Tianjin-Hebei region was divided into three cooperative control regions for PM2.5 and O3. The average annual concentration of PM2.5 in Beijing-Tianjin-Hebei decreases by 42.19% from 2017 to 2022, with a significant downward trend, while the average annual concentration of MDA8O3 decreases by 1.85%, with a fluctuating trend; the areas with severe PM2.5 are also the areas with deteriorating O3, and spatially show the characteristics of "high in the south and low in the north"; The eastern densely populated cities represented by Beijing and Tianjin have high health risks of PM2.5 and O3 exposure, with October-March as the health control period for PM2.5 and April-September as the collaborative health control period for PM2.5 and O3; Beijing-Tianjin-Hebei is divided into three cooperative control regions. The composite pollution characteristics of the three zones are more similar to each other.
