With　the　proposal　of　＂carbon　peak＂　and　＂carbon　neutralization＂,　Liquefied　Natural　Gas　(LNG)　has　gradually　garnered　the　attention　of　energy　market　as　a　clean　and　low-carbon　energy.　In　this　context,　it　is　of　great　significance　to　analyze　the　evolution　mode　of　the　LNG　maritime　transport　network,　so　as　to　master　the　dynamic　of　global　energy　pattern　and　the　status　of　China＇s　import　trade.　In　this　paper,　the　evolution　trend　of　the　global　LNG　maritime　transport　network　from　2018　to　2020　is　explored　based　on　the　ship　trajectory　data　and　complex　network　theory.　Meanwhile,　according　to　China＇s　trade　status,　LNG　import　sources,　distribution　of　main　import　ports,　and　the　inflow　status　of　the　top　three　import　ports　in　China　are　analyzed.　The　results　show　that:　(1)　From　2018　to　2020,　the　global　LNG　maritime　transport　network　expanded　with　a　＂scale-free＂　characteristic.　The　＂breadth＂　and　＂depth＂　of　node　connections　in　the　backbone　network　are　increasing,　and　there　is　a　risk　that　global　LNG　trade　will　become　monopolistic;　(2)　The　countries　along　the　＂Belt　and　Road　Initiative＂　actively　participated　in　trade.　The　numbers　of　import　ports　and　import　voyages　in　Central　and　North　America,　South　and　Southeast　Asia　have　significantly　increased,　and　in　particular,　Sabetta　and　Bonny　ranked　the　top　eight　globally　according　to　their　export　volume;　(3)　The　average　shortest　path　length　of　the　network　is　increasing　year　by　year　from　2018　to　2020,　and　the　new　mode　of　＂transshipment　port＂　business　is　gradually　emerging.　By　2020,　21　transshipment　ports　have　participated　in　LNG　trade,　and　the　United　States　occupies　the　dominant　position　in　global　transshipment;　(4)　In　recent　three　years,　China＇s　LNG　import　scale　has　developed　rapidly,　and　the　flow　direction　of　the　maritime　transport　network　tends　to　be　diversified.　However,　Australia　is　still　the　main　LNG　source　for　China.　In　terms　of　import　volume,　the　ports　of　Tianjin,　Shenzhen,　and　Yung＇an　rank　the　top　three　in　China,　and　the　pressure　to　reduce　carbon　emissions　has　prompted　the　economically　developed　regions　to　build　terminals　and　increase　imports.　©　2022,　Science　Press.　All　right　reserved.
