The global spread of COVID-19 has led to profound reflection on building a global public health security system. This paper uses the urban data collected during the COVID-19 epidemic in China in 2020 to evaluate the effect of the National Sanitary City (NSC) policy on the prevention and control of that epidemic at different stages. We found that the NSC policy was able to curb the occurrence and transmission of the epidemic the epidemic effectively after controlling a series of factors such as urban characteristics, population mobility and pathogen transmission. Compared with non-NSCs, the NSCs were better able to control the number of infected people and the infection rate and transmission rate, and this performance was even more impressive when the epidemic gradually entered the sporadic distribution stage. The heterogeneity analysis shows that the impact of the NSC policy on the prevention and control of COVID-19 differs according to the economic development level and population size. To a certain extent, the NSC policy has blocked the spread of viruses by continuously improving the urban medical and health system and strengthening the publicity concerning infectious disease prevention and control knowledge.
新冠疫情的全球蔓延促使人们对构建全球公共卫生安全体系进行深刻反思。本文利用 2020 年中国新冠疫情期间收集的城市数据，评估了国家卫生城市（NSC）政策在疫情不同阶段对疫情防控的效果。研究发现，在控制城市特征、人口流动和病原体传播等一系列因素后，NSC 政策能够有效遏制疫情的发生和传播。与非 NSCs 相比，NSCs 能够更好地控制感染人数、感染率和传播率，而当疫情逐渐进入散发阶段时，这一表现更为显著。异质性分析表明，NSC 政策对 COVID-19 的防控效果因经济发展水平和人口规模而异。在一定程度上，NSC 政策通过不断完善城市医疗卫生体系和加强传染病防控知识宣传，阻止了病毒的传播。
