基于大数据的武汉市疫后人口恢复研究

Research on Population Recovery after Epidemic in Wuhan City Based on Big Data

利用手机信令和百度位置服务大数据,以2019年为基准,从居住与就业人口、对外城际联系和内部人口流动3个方面分析了2020年武汉市疫后人口恢复情况。研究结果表明,截至2020年12月,武汉市居住、就业人口分别恢复至基准时段的97%和92%,但内部区域差异明显,与经济发展水平密切相关;截至2020年9月,城市内部人口流动已恢复到基准时段的90%,但全国范围城际间联系恢复仅五成,省内联系恢复较好,劳动力流动恢复高于商务往来。

Based on the mobile signaling and Baidu location service big data,we analyzed the population recovery of Wuhan in 2020 from three aspects,including residential and employed population,external intercity connection and internal population flow.The results show that as of December 2020,the residential and employed population in Wuhan has recovered to 97%and 92%of the population in the benchmark period respectively,but there are significant regional differences,which are closely related to the economic development level.As of September 2020,the population flow within cities has recovered to 90%of the flow in the benchmark period,but only 50%of the intercity connection across the country have recovered.The provincial connection have recovered well,and the labor flow has recovered more than business exchange.
