Abstract  

[Objective] This paper quantifies the offline resumption level after public emergencies, aiming to provide data support for making and implementing policies.[Methods] First, we used manual and automated POI fence delineation strategies to obtain the number of mobile devices in 931 areas. Then, we measured the offline resumption levels based on the number of mobile devices within each company’s physical settings. Finally, we evaluated the measurements with facts and related data.[Results] We found that for days immediately following the Spring Festival 2020, the average level of offline resumption in the sampled companies was about 30% of that of the same period in 2019. At the end of February 2020, about half of the employees from the sampled companies returned to work offline.[Limitations] The sample size needs to be expanded.[Conclusions] The proposed method could dynamically monitoring offline work resumption after public emergencies.
