Increasingly　frequent　urban　waterlogging　disasters　are　having　profound　social　and　economic　consequences.　An　appropriate　and　integrated　evaluation　of　the　total　economic　impacts　of　such　disasters　is　crucial　for　achieving　effective　urban　disaster　risk　management　and　sustainable　development.　However,　existing　metrics　are　inadequate　for　measuring　the　economic　impacts　of　rainfall　events　of　different　intensities　and　their　ripple　effects　across　regions.　Moreover,　their　ecological　impacts　have　received　insufficient　attention.　To　address　these　gaps,　we　developed　an　integrated　assessment　framework　for　analyzing　urban　waterlogging　losses　and　evaluating　their　various　impacts.　Taking　Beijing　as　a　case　study,　we　used　the　InfoWorks　ICM　model　to　simulate　urban　waterlogging　disaster　risks,　quantified　direct　economic　losses,　and　assessed　their　environmental　impacts.　Additionally,　we　estimated　indirect　economic　losses　using　input-output　analysis　and　explored　spillover　effects.　The　results　revealed　increasing　trends　of　direct　economic　losses　and　environmental　losses　corresponding　to　a　longer　return　period.　We　observed　synergies　between　these　losses　and　their　spatial　heterogeneity.　However,　indirect　impacts　far　outweighed　direct　impacts,　with　the　former　being　2.43　times　larger　than　the　latter.　The　cascading　effect　resulting　from　damage　to　infrastructure　was　also　particularly　pronounced.　The　industrial　and　spatial　heterogeneity　of　interregional　impacts　was　striking,　with　eastern　provinces　evidencing　the　most　significant　effects.　By　mapping　the　transmission　paths　of　disaster　losses　along　industrial　chains　and　across　regions,　this　study　provides　inputs　that　could　assist　policymakers　in　developing　more　effective　measures　for　preventing　and　mitigating　urban　waterlogging　disasters.
