论文摘要
随着Covid-19的传输在全球范围内传播，政府已经宣布并强制执行旅行限制，以防止进一步的感染。这种限制对这些国家之间的国际航班数量有直接影响，从而导致了广泛的社会和经济成本。为了更好地了解情况，我们使用了Opensky网络数据来阐明世界各地的飞行模式和飞行密度，并观察到飞行数量与新感染以及巴塞罗那经济（失业率）之间的关系。我们发现，在美国和欧洲颁布了旅行限制之后的2020年3月下半年，每日航班的数量逐渐减少，突然下降了64％。我们还观察到在此期间，全球飞行网络密度降低了51％。关于新的Covid-19案件，无论旅行限制如何，世界都有意外的激增。最后，在西班牙决定关闭边界后的几周内，旅游业和飞机业务的临时工裁员增加了4.3倍。
As COVID-19 transmissions spread worldwide, governments have announced and enforced travel restrictions to prevent further infections. Such restrictions have a direct effect on the volume of international flights among these countries, resulting in extensive social and economic costs. To better understand the situation in a quantitative manner, we used the Opensky network data to clarify flight patterns and flight densities around the world and observe relationships between flight numbers with new infections, and with the economy (unemployment rate) in Barcelona. We found that the number of daily flights gradually decreased and suddenly dropped 64% during the second half of March in 2020 after the US and Europe enacted travel restrictions. We also observed a 51% decrease in the global flight network density decreased during this period. Regarding new COVID-19 cases, the world had an unexpected surge regardless of travel restrictions. Finally, the layoffs for temporary workers in the tourism and airplane business increased by 4.3 fold in the weeks following Spain's decision to close its borders.
