Since　the　European　Commission　proposed　in　July　2021　to　implement　a　Carbon　Border　Adjustment　Mechanism　(CBAM),　the　impact　mechanism　has　received　increasing　attention　worldwide.　This　study　aims　to　analyze　the　impact　of　carbon　border　tariffs　on　China＇s　carbon-intensive　industries　and　simulate　the　risk　transmission　within　China＇s　industrial　complex　network　based　on　the　complex　network　modeling　and　cascading　failure　analysis.　The　results　showed　that　the　industries　subject　to　carbon　border　tariffs　played　an　essential　role　in　China＇s　entire　industrial　structure,　which　is　closely　related　to　industries　including　construction,　metal,　and　manufacturing.　If　the　carbon　border　tariffs　are　imposed　on　the　steel　industry,　China＇s　relevant　industries　will　be　reduced　by　1.29%,　followed　by　the　fertilizer　industry　and　non-ferrous　metal　industry　with　proportions　of　1.11%　and　0.95%,　respectively.　When　the　industrial　transmission　threshold　reaches　0.8,　the　export　shocks　will　affect　the　entire　industrial　network,　leading　to　a　rapid　growth　in　the　number　of　infected　industries.　By　depicting　the　industrial　linkage　and　impact　mechanism　of　carbon　border　tariffs,　this　study　is　expected　to　provide　practical　suggestions　and　implications　for　carbon-intensive　industries　towards　sustainable　low-carbon　transition　under　carbon　border　tariffs.
