Utilizing　the　UN　Comtrade　database＇s　iron　ore　trade　data　from　1991　to　2020,　this　study　employs　complex　network　theory　to　construct　a　global　iron　ore　trade　network.　The　trade　pattern　is　analyzed　using　network　parameters,　such　as　average　degree,　average　clustering　coefficient,　heterogeneity,　and　centrality　index.　Findings　reveal　a　highly　heterogeneous　global　iron　ore　trade　network　dominated　by　a　few　core　countries,　exhibiting　extreme　fragility.　China,　Japan,　and　South　Korea　hold　significant　import　market　positions,　with　Asia＇s　influence　growing.　Australia　and　Brazil　dominate　the　export　market,　while　Canada　and　South　Africa　demonstrate　promising　export　potential.　The　Netherlands,　the　United　States,　Germany,　and　Turkey　serve　as　iron　ore　trading　hubs,　playing　a　crucial　role　in　resource　supply　security.　©　2023　ACM.
