论文摘要
在本文中，我们研究了COVID-19数据在国家一级的趋势行为，并引起人们对某些现有的计量经济学工具的关注，这些工具可能有助于了解未来研究的趋势。在我们的实证研究中，我们发现与其他地区相比，欧洲国家总体上更有效地将曲线更有效，而亚洲和大洋洲也取得了成功，但是在其他地方，情况并不乐观。在管理病毒的传播方面，非洲和美国仍然面临严重的挑战，尽管在非洲，病毒的传播速度较慢，并且死亡率较低，而死亡率则低于其他地区。通过比较不同国家的表现，我们的结果偶然地与Gu等人一致。 （2020），尽管考虑了不同的方法和模型。例如，两者都同意，美国，英国和意大利等国家的表现相对较差。另一方面，澳大利亚，中国，日本，韩国和新加坡的表现相对较好。
In this paper, we study the trending behaviour of COVID-19 data at country level, and draw attention to some existing econometric tools which are potentially helpful to understand the trend better in future studies. In our empirical study, we find that European countries overall flatten the curves more effectively compared to the other regions, while Asia & Oceania also achieve some success, but the situations are not as optimistic elsewhere. Africa and America are still facing serious challenges in terms of managing the spread of the virus, and reducing the death rate, although in Africa the virus spreads slower and has a lower death rate than the other regions. By comparing the performances of different countries, our results incidentally agree with Gu et al. (2020), though different approaches and models are considered. For example, both works agree that countries such as USA, UK and Italy perform relatively poorly; on the other hand, Australia, China, Japan, Korea, and Singapore perform relatively better.
