The purpose of this paper was to compare the relative efficiency of COVID-19 transmission mitigation among 23 selected countries, including 19 countries in the G20, two heavily infected countries (Iran and Spain), and two highly populous countries (Pakistan and Nigeria). The mitigation efficiency for each country was evaluated at each stage by using data envelopment analysis (DEA) tools and changes in mitigation efficiency were analyzed across stages. Pearson correlation tests were conducted between each change to examine the impact of efficiency ranks in the previous stage on subsequent stages. An indicator was developed to judge epidemic stability and was applied to practical cases involving lifting travel restrictions and restarting the economy in some countries. The results showed that Korea and Australia performed with the highest efficiency in preventing the diffusion of COVID-19 for the whole period covering 105 days since the first confirmed case, while the USA ranked at the bottom. China, Japan, Korea, and Australia were judged to have recovered from the attack of COVID-19 due to higher epidemic stability.
本文旨在比较23个选定国家（包括20国集团中的19个国家、两个疫情严重国家（伊朗和西班牙）以及两个人口大国（巴基斯坦和尼日利亚））在减轻新冠病毒传播方面的相对效率。利用数据包络分析（DEA）工具在每个阶段评估每个国家的缓解效率，并分析各阶段缓解效率的变化。对每个变化进行Pearson相关性检验，以考察前一阶段的效率排名对后续阶段的影响。制定了一个指标来判断疫情稳定性，并将其应用于一些国家解除旅行限制和重启经济的实际案例。结果显示，自首例确诊病例以来的105天内，韩国和澳大利亚在防止新冠病毒传播方面的效率最高，而美国排名垫底。中国、日本、韩国和澳大利亚因较高的疫情稳定性而被判定已从新冠疫情的冲击中恢复过来。
