Fuel　is　the　cornerstone　of　a　nation＇s　economy,　and　energy　policy　is　a　crucial　part　of　national　security.　Therefore,　it　is　very　important　to　model　and　analyze　the　fuel　trade.　In　this　paper,　a　dynamic　system　by　a　visibility　graph　model　is　constructed　to　analyze　time　series　data　from　the　global　fuel　export　trade.　This　paper　analyses　the　fuel　export　trade　of　various　countries,　and　the　characteristics　of　fuel　trade　in　different　countries　are　identified　by　the　visibility　graph.　According　to　the　characteristics　of　the　fuel　export　time　series　network,　the　examined　countries　are　categorized,　and　the　global　fuel　export　market　is　divided　into　three　groups.　It　has　important　guiding　significance　for　understanding　the　global　fuel　market　and　formulating　scientific　fuel　security　policies.(c)　2021　Published　by　Elsevier　Ltd.
