Cities　play　critical　roles　in　achieving　carbon-neutrality,　and　the　pathways　to　the　carbon-neutral　goal　are　different　because　of　cities＇　various　developmental　levels.　On　the　basis　of　the　industrial　structure　and　energy　intensity,　＂2　thorn　26＂　cities　were　classified　firstly.　With　LEAP-city　model　built,　the　gaps　and　pathways　to　carbon　neutrality　for　different　city　types　(SCJ,　CCL,　CCX,　and　ICZ)　are　analyzed　under　the　policy　(PO)　and　low-carbon　(LC)　scenarios.　Results　show　that　CCL　and　CCX　would　be　carbon-neutral　without　carbon　capture　and　storage　(CCS)　technology　in　the　LC　scenario.　If　SCJ　and　ICZ　apply　the　CCS　for　the　power　and　heating　plants,　they　can　be　carbon　neutral　in　2049　and　2050,　respectively.　Regarding　CO2　emissions,　the　industry　sector　in　all　energy　demand　sectors　is　always　the　most　key　sector　for　CCX　and　ICZ　from　2016　to　2030,　which　means　optimizing　production　processes　and　reducing　surplus　output　are　very　important.　After　high　energy-consuming　industries　are　moved　out　CCL　and　SCJ,　CO2　emissions　from　transportation　and　buildings　are　the　challenges.　Therefore,　instead　of　fuel　vehicles,　zero-carbon　vehicles　are　the　first　option.　Electrification　and　zero-carbon　energy　used　in　buildings　are　the　priorities　combined　with　the　decarbonization　of　electricity,　which　would　also　be　a　highly　efficient　measure　in　the　industry　sector　after　2030.
