In this letter, we find a Simpson’s paradox in the association between GDP and COVID-19 transmission in Chinese cities stratified by location. The differential associations in cities within and outside Hubei province can be explained by different patterns of short-range and long-range multiscale mobility from Wuhan to other cities.
在这封信中，我们发现 GDP 与中国城市 COVID-19 传播之间的关联存在辛普森悖论，这种关联按地理位置在中国城市进行分层。湖北省内和省外城市之间的关联差异可以用武汉与其他城市之间短程和远程多尺度流动的不同模式来解释。
