Evaluation　of　urban　planning　and　development　is　becoming　more　and　more　important　due　to　the　large-scale　urbanization　of　the　world.　With　the　application　of　mobile　phone　data,　people　can　analyze　the　development　status　of　cities　from　more　perspectives.　By　using　the　mobile　phone　data　of　Beijing,　the　working　population　density　in　different　regions　was　identified.　Taking　the　working　population　density　in　Beijing　as　the　research　object　and　combining　the　land　use　of　the　city,　the　development　status　of　Beijing　was　evaluated.　A　geographically　weighted　regression　model　(GWR)　was　used　to　analyze　the　difference　in　the　impact　of　land　use　on　the　working　population　between　different　regions.　By　establishing　a　correlation　model　between　the　working　population　and　land　use,　not　only　can　the　city＇s　development　status　be　evaluated,　but　it　can　also　help　city　managers　and　planners　to　make　decisions　to　promote　better　development　of　Beijing.
