Based on DEA, this paper evaluates the matching of urban rail transit stations and analyzes the influencing factors. Five non-transfer stations of urban rail transit in Dalian were selected as the research objects, relevant data were obtained through field investigation, and the matching of station facilities and equipment were analyzed. The results showed that the main reasons for the low comprehensive efficiency of station facilities were insufficient passenger flow output and waste of resources in the station equipment and facilities. By analyzing the sensitivity of the index, it is concluded that the number of escalators, the width of stairs and the matching degree of the capacity of escalators have an impact on the matching degree of urban rail transit stations, among which the width of stairs has the greatest influence.
