Arrearage data processing method, device and system

The invention provides an arrearage data processing method, device and system, and belongs to the technical field of finance or other technical fields. The arrearage data processing method comprises the following steps: acquiring arrearage data, wherein the arrearage data comprises a frequency mark, a current-day posting amount, an account state and an arrearage day number; generating a current threshold number of days according to the historical threshold number of days, the frequency mark, the amount of entry on that day, the account state and the arrearage number of days; and generating an arrearage data processing result according to a comparison result of the current threshold value day number and the arrearage day number. According to the method, data idling can be reduced, the processing efficiency is improved, and the supplementary deduction success rate is improved while the processing pressure of a host system is reduced and the processing time is shortened. 本发明提供一种欠费数据处理方法、装置及系统，属于金融技术领域或其他技术领域。该欠费
