We collected COVID-19 epidemiological and epidemic control measures-related data in mainland China during the period January 1 to February 19, 2020, and empirically tested the practical effects of the epidemic control measures implemented in China by applying the econometrics approach. The results show that nationally, both traffic control and social distancing have played an important role in controlling the outbreak of the epidemic, however, neither of the two measures have had a significant effect in low-risk areas. Moreover, the effect of traffic control is more successful than that of social distancing. Both measures complement each other, and their combined effect achieves even better results. These findings confirm the effectiveness of the measures currently in place in China, however, we would like to emphasize that control measures should be more tailored, which implemented according to each specific city's situation, in order to achieve a better epidemic prevention and control.
我们收集了2020年1月1日至2月19日期间中国大陆与新冠疫情流行病学及疫情防控措施相关的数据，并运用计量经济学方法实证检验了中国实施的疫情防控措施的实际效果。结果表明，在全国范围内，交通管制和社交距离措施在控制疫情爆发方面都发挥了重要作用，然而，这两项措施在低风险地区均未产生显著效果。此外，交通管制的效果比社交距离措施更显著。这两项措施相辅相成，它们的综合效果更佳。这些发现证实了中国目前采取的措施的有效性，然而，我们想强调的是，防控措施应更具针对性，即根据每个具体城市的情况实施，以实现更好的疫情防控。
