Replication Data for: Racial Resentment and Support for COVID-19 Travel Bans in the United States

Travel bans were a globally prevalent policy response to the COVID-19 pandemic. In the United States, travel bans against China and European countries proved a broadly popular mitigation tool among Americans. Why did Americans support COVID-19 travel bans? We fielded two novel survey experiments, surveying 3,000 American citizens across five waves (between March 2020 – March 2021). In randomizing the country of origin of those potentially subject to travel ban measures, we find consistent evidence that racial attitudes drive support for travel bans. The strength of this relationship varies across political parties and across hypothetical target countries but is not explained by objective caseloads that change across countries and over the course of the pandemic.旅行禁令曾是全球范围内应对新冠疫情（COVID-19）的主流政策举措。在美国，针对中国及欧洲多国的旅行禁令被证实是广受美国民众认可的疫情缓控手段。那么，美国民众为何会支持新冠疫情旅行禁令？本研究开展了两项创新性调查实验，于2020年3月至2021年3月期间分五轮调研了3000名美国公民。通过随机设定可能受旅行禁令限制的人群的来源国，本研究获得了一致的实证证据：种族态度是推动民众支持旅行禁令的核心动因。该关联的强度会因政党派别以及假设的目标国家不同而存在差异，但无法通过不同国家及疫情不同阶段的客观病例数来解释。
