Critical　Mineral　is　the　important　material　basis　for　achieving　carbon　neutrality.　Under　a　low-carbon　scenario,　the　demand　for　nickel　in　the　new　energy　will　grow　rapidly,　which　may　lead　to　supply　shortages.　Under　the　Russia-Ukraine　conflict,　the　nickel　trade　changes　frequently　and　the　trade　will　become　more　complicated.　To　clarify　the　risk　transmission　mechanism,　based　on　the　nickel　products　trade　data　of　UN　COMTRADE,　this　paper　combines　econometrics　and　complex　network　methods　to　construct　the　Global　Nickel　Industry　Chain　Trade　Behavior　Transmission　Network　(GNICTBTN).　The　research　shows　that　the　Main　Transmission　System　of　the　GNICTBTN　includes　18　countries　and　25　trade　links,　of　which　6　trade　links　need　to　be　paid　attention　to　in　the　middle　and　early　stages　of　trade　changes,　and　it　indicates　that　nickel　resource　is　at　risk　of　being　monopolized　by　middlemen.　This　study　distinguishes　the　industrial　chain　structure　of　seven　key　countries,　and　finds　that　the　relevance　of　trade　links　is　closely　related　to　trading　transmission　risk.　According　to　GNICTBTN,　we　predict　that　the　Russia　-Ukraine　conflict　will　affect　the　developing　countries　in　the　Asia-Pacific　region　and　developed　countries　in　Europe　and　USA　in　short　term,　and　repeatedly　affects　the　main　transmission　system　for　longer.
