Based on the financial performance data of Chinese listed companies from 2006 to 2021,the relationship between urban rail transit construction,labor mobility and enterprise performance has been analyzed by using SD analysis method and time-varying DID model.The results show that the construction of urban rail transit can accelerate labor mobility and improve the overall performance of enterprises,but there are significant differences between the short and medium term influence mechanisms.While improving enterprise performance,rail transit construction obliges enterprises to add additional human capital investment to a certain extent in a certain period of time,and this influence shows a certain"polarization effect"in location.Therefore,enterprises should strengthen human capital investment,introduce talents and retain talents according to the trend of accelerated labor mobility,so as to promote the enterprise performance.
