新型冠狀病毒（COVID-19）疫情波及全球，而原為多國所採用的避免群聚政策，也因影響經濟甚鉅，近來多數國家的防疫政策轉型為「與病毒共存」。本研究使用中央研究院社會學研究所執行2003年第一次社會意向調查，當時台灣正值SARS冠狀病毒疫情，該問卷調查中含有防疫行為問題。依照需求理論，分析避免群聚與非藥物性防疫措施影響因素。結果發現影響民眾採取避免群聚行為的因素為「症狀了解程度」、「是否擔憂罹患疾病」及「預期距離疫情控制月數」，非藥物性防疫措施與避免群聚行為之間沒有內生關係。

The COVID-19 pandemic has spread globally. The policy of social distancing, which was originally adopted by many countries, has also been transformed due to the huge impact on the economy. In order to coexist with the virus, this study used the data of the 2003 first Social Image Survey which includes questions about personal epidemic prevention behaviors conducted during the SARS epidemic in Taiwan to analyze the behaviors of crowd avoidance and non-pharmaceutical interventions (NPIs). According to the theory of demand, we found that the awareness of symptoms, the warry of affection, and the expected time to epidemic under control can significantly affect the behavior of crowd avoidance. There is no endogenous relationship between non-pharmaceutical interventions and crowd avoidance behavior.
