The　current　green　industrial　Internet　system　has　many　problems　in　energy　efficiency,　privacy,　resource　management,　etc.,　and　more　technologies　from　different　fields　need　to　be　integrated　to　realize　the　development　of　green　industrial　Internet.　The　current　research　and　implementation　technologies　were　summarized,　and　an　outlook　on　the　development　and　challenges　of　green　industrial　Internet　was　provided.　First,　the　basic　architecture　and　technical　characteristics　of　industrial　Internet　were　introduced,　and　the　realization　path　of　“greening＂　industrial　Internet　was　discussed　from　multiple　perspectives　around　the　frontier　network　technologies,　such　as　green　communication,　mobile　edge　computing,　blockchain,　etc.　Second,　the　development　status　of　green　industrial　Internet　and　the　key　technologies　involved　in　the　construction　of　actual　scenarios　were　summarized　in　detail.　Finally,　in　view　of　the　problems　and　challenges　faced　in　the　development　of　green　industrial　Internet　at　this　stage,　the　solutions　and　development　trends　of　building　a　green　industrial　Internet　system　were　discussed.　©　2023　Beijing　University　of　Technology.　All　rights　reserved.
