As　the　main　way　of　international　capital　flow　and　an　important　carrier　of　international　technology　spillover,　have　inward　foreign　direct　investment　(IFDI)　and　outward　foreign　direct　investment　(OFDI)　improved　the　green　development　quality　of　the　logistics　industry?　Based　on　the　panel　data　of　27　provinces　in　China　from　2006　to　2015,　this　paper　uses　the　panel　model　to　empirically　test　the　impact　of　two-way　FDI　on　the　green　development　quality　of　the　logistics　industry.　This　paper　mainly　draws　the　following　research　conclusions:　(1)　Two-way　FDI　had　significantly　improved　the　green　development　quality　of　the　logistics　industry,　and　the　promotion　effect　of　IFDI　was　stronger　than　that　of　OFDI,　indicating　that　two-way　FDI　is　a　key　approach　of　enhancing　the　quality　of　the　green　development.　(2)　The　impact　of　two-way　FDI　on　the　green　development　quality　has　spatial-temporal　heterogeneity.　Specifically,　only　in　the　eastern　region,　IFDI　and　OFDI　have　played　a　significant　role　in　promoting　the　green　development　of　the　logistics　industry　at　the　same　time;　the　role　of　IFDI　in　improving　the　green　development　quality　of　the　logistics　industry　has　weakened　over　time,　while　OFDI　has　strengthened.　(3)　The　effect　of　two-way　FDI　on　the　green　development　quality　of　the　logistics　industry　was　affected　by　the　environmental　regulation　intensity.　With　the　improvement　of　environmental　regulations　intensity,　the　impact　of　IFDI　on　the　green　development　quality　of　the　logistics　industry　presents　an　“inverted　U”　trend　that　first　rises　and　then　decreases.　The　impact　of　OFDI　on　the　green　development　quality　of　the　logistics　industry　presents　a　gradually　increasing　characteristic.　©　2023,　HARD　Publishing　Company.　All　rights　reserved.
