As　a　crucial　event　in　the　process　of　China＇s　trade　cooperation　and　openness,　the　Belt　and　Road　Initiative　(BRI)　relies　on　the　logistics　as　the　foundational　industry　for　its　sustainable　development.　This　study　measures　the　green　logistics　efficiency　(GLE)　of　BRI　partner　countries　using　panel　data　from　2013　to　2019　and　evaluates　the　BRI＇s　impact　on　their　GLE.　We　find　that:　(1)　The　GLE　of　BRI　partner　countries　is　generally　low,　with　only　15.9%　achieving　effectiveness.　High-income　countries　have　notably　higher　GLE　than　middle-income　ones.　(2)　The　GLE　of　BRI　partner　countries　shows　an　upward　trend　annually,　especially　in　middle-income　countries,　which　are　closing　the　gap　with　high-income　countries.　(3)　The　BRI　has　a　significant　positive　impact　on　the　GLE　growth　of　partner　countries.　Heterogeneity　analysis　reveals　that　this　growth　effect　is　more　pronounced　in　middle-income　countries.　These　results　indicate　and　enhance　the　understanding　of　GLE　among　BRI　partner　countries　and　addresses　some　skepticism　regarding　BRI＇s　sustainable　development.　©　2024　The　Authors
