：　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.　©　2024　Chinese　Society　for　Environmental　Sciences.　All　rights　reserved.
