Identifying　effective　transformations　to　reduce　poverty　and　approach　rural　sustainability　is　at　the　core　of　the　first　sustainable　development　goal　of　the　United　Nations.　This　article　offers　scientific　support　for　continued　efforts　in　sustaining　rural　development　and　livelihood　resilience.　Many　studies　have　examined　drivers　of　livelihood　transition　from　farming　to　non-farm　activities,　especially　participation　in　tourism　against　the　backdrop　of　rural　tourism　development.　However,　few　studies　have　identified　ways　to　measure　the　level　of　tourism　participation　or　have　discussed　how　household-level　capital　influences　decisions　regarding　tourism　participation　made　by　Tibetan　ethnic　households.　This　article　assesses　the　role　of　livelihood　capital　in　the　adoption　of　tourism　activities　at　the　household　level　in　Jiaju　Tibetan　Village,　an　ethnic　region　that　is　experiencing　struggling　agricultural　business　and　developing　tourism　sector.　Using　household　survey　data,　this　study　presents　an　ordinal　logistic　regression　model　to　identify　the　determinants　of　the　household　tourism　participation　level.　The　results　showed　that　households’　tourism　participation　was　influenced　by　physical　capital　(e.g.,　proximity　to　major　roads,　odds　ratio　=　2.83　at　p　=　0.024;　fixed　capitals,　odds　ratio　=　101.19　at　p　=　0.039),　human　capital　(e.g.,　availability　of　family　labor,　odds　ratio　=　0.25　at　p　=　0.004;　availability　of　skilled　member,　odds　ratio　=　2.91　at　p　=　0.002),　and　social　capital　(e.g.,　relatives　in　governmental　sectors,　odds　ratio　=　5.22　at　p　=　0.044;　government　payments,　odds　ratio　=　8.78　at　p　=　0.04),　while　the　influence　of　financial　capital　was　not　significant.　The　proximity　to　major　roads,　availability　of　skilled　members,　fixed　assets,　and　direct　and　indirect　support　from　the　government　to　households　were　significantly　and　positively　associated　with　tourism　participation　level.　The　effects　of　household　labor　availability　and　annual　family　income　remain　unclear.　Overall,　household　livelihood　capital　plays　a　critical　role　in　the　enhancement　of　tourism　participation　in　Jiaju　Tibetan　Village.　Our　findings　have　implications　for　understanding　the　shift　of　on-farm　occupation　to　off-farm　activities　in　tourism　and　for　the　pursuit　of　policies　contributing　to　poverty　reduction　and　rural　revitalization　in　China　as　well　as　to　the　Sustainable　Development　Goals.　©　2022　by　the　authors.
