The invention provides a data processing method and a data processing device for browsing internet records of mobile subscribers. The method comprises the following steps of (S110) establishing N data according to each browsing internet record in a preset time quantum; and (S120) accumulating statistical information in the data with the same identifications to obtain accumulated values of the statistical information corresponding to the identifications. Each datum comprises an identification and statistical information, each identification comprises a cell-phone number, a data type and a record type in the corresponding browsing internet record, the data are in N types, the N types of the data correspond to N preset fields in the browsing internet records one by one, the data types of the N data established by each browsing internet record are different, the record type of each datum is a value of the corresponding preset field, which corresponds to the corresponding data type in the datum, in the datum, and N is a positive integer greater than 1. By the data processing method and the data processing device for the browsing internet records of the mobile subscribers, the processing speed of mobile internet data can be increased.
