Cleaner　heating　policies　aim　to　reduce　air　pollution　and　may　bring　about　health　benefits　to　individuals.　Based　on　a　fixed　-effect　model　focusing　on　Beijing,　this　study　found　that　after　the　onset　of　air　pollution,　daily　clinic　visits,　hospitalization　days,　and　hospitalization　expenses　increased　several　days　after　the　occurrence　of　air　pollution.　These　hospitalization　changes　were　observed　in　males　and　females　and　three　different　age　groups.　A　difference　-in　-differences　(DID)　model　was　constructed　to　identify　the　influences　of　cleaner　heating　policies　on　health　consequences.　The　study　revealed　that　the　policy　positively　affects　health　outcomes,　with　an　average　decrease　of　3.28　thousand　clinic　visits　for　all　diseases.　The　total　hospitalization　days　and　expenses　tend　to　decrease　by　0.22　thousand　days　and　0.34　million　CNY　(Chinese　Yuan),　respectively.　Furthermore,　implementing　the　policy　significantly　reduced　the　number　of　daily　clinic　visits　for　respiratory　diseases,　asthma,　stroke,　diabetes,　and　chronic　obstructive　pulmonary　diseases　(COPDs).
