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).
清洁取暖政策旨在减少空气污染，并可能给个人带来健康益处。基于聚焦北京的固定效应模型，本研究发现，空气污染发生后，空气污染出现数天后的每日门诊就诊量、住院天数和住院费用均有所增加。这些住院变化在男性和女性以及三个不同年龄组中均有观察到。构建了一个双重差分（DID）模型来确定清洁取暖政策对健康后果的影响。研究表明，该政策对健康结果有积极影响，所有疾病的门诊就诊量平均减少3280次。总住院天数和费用分别趋于减少220天和34万元人民币。此外，实施该政策显著减少了呼吸系统疾病、哮喘、中风、糖尿病和慢性阻塞性肺疾病（COPD）的每日门诊就诊量。
