Abstract：As the polycentric structure has become the development strategy of large cities， it's of great significance to explore the relationship between centers and find the formation mechanism of employment centers. Therefore， with Wuhan as the research area， in this research employment centers are identified with their inner relationship analyzed through a residual analysis method and mathematical statistical models based on geographic big data， such as mobile app data， POI data and geographic census data. Then Logistic regression methods is applied to reveal the dynamic mechanism of Wuhan's employment centers. Conclusions are as follows. 1) Wuhan City has significant polycentric spatial pattern， and the relationship between the centers of Wuhan is manifested as the functional complementarity between the main center and the nearest subcenter. 2) The diversification index， service sector， traffic network density and Wuhan City Master Plan (2010-2020) play a significant role on the formation of employment subcenters in Wuhan. To optimize the industrial structure and formulate the scientific urban planning are the important measures to promote the formation and development of employment subcenters. 3) Labor agglomeration and Wuhan City Master Plan (1996－2020) have significant and relatively significant hindering effect on the formation of Wuhan employment subcenters， respectively.
