Urban　areas＇performance　in　water,energy,infrastructure,and　socio-economic　sectors　is　intertwined　and　measurable　through　Sustainable　Development　Goals(SDGs)6-13.Effective　synergy　among　these　is　critical　for　sustainability.This　study　constructs　an　indicator　frame-work　that　reflects　progress　towards　these　urban　SDGs　in　China.Findings　indicate　underper-formance　in　SDGs　8-11,suggesting　the　need　for　transformative　actions.Through　network　analysis,the　research　reveals　complementarities　among　these　SDGs.Notably,the　SDG　space　divides　into　socio-economic　and　ecological　clusters,with　SDG　6(Clean　Water　and　Sanita-tion)central　to　both.Additionally,SDG　8(Decent　Work　and　Economic　Growth)and　SDG　9(Industry,Innovation,and　Infrastructure)act　as　bridges,while　greater　synergies　exist　be-tween　SDG　12(Responsible　Consumption　and　Production)and　SDG　13(Climate　Action).An　in-depth　view　at　the　indicator-level　shows　a　core-periphery　structure,emphasizing　indi-cators　like　SDG　6.2(Wastewater　Treatment　Rate)and　SDG　6.6(Recycled　Water　Production　Capacity　per　capita)as　pivotal.This　study　confirms　the　urban　SDG　space＇s　stability　and　pre-dictiveness,underscoring　its　value　in　steering　well-aligned　policy　decisions　for　sustainable　growth.
