The relationship between residents′ income and ticket prices directly affects the commuting choice of urban rail transit passengers. According to existing researches on the impact of ticket prices on commuting travel, the level of ticket price is defined firstly. Secondly, based on the investigation of Beijing, Guangzhou, Tianjin, Wuhan, Dalian and Changchun, passengers are required to answer the questions based on daily commuting behavior, and a PLS-SEM model and a mediator model are established to analyze the influence mechanism of ticket prices on commuting travel behavior in different types of cities. The result of study shows the influence mechanism that the rationality of ticket prices affects perceived value and then travel intention. Among them, the effect of ticket price per person on perceived value is new first-tier cities(0.862), first-tier cities(0.838), secondtier cities (0.782). Ticket price per person affects perceived value through the ticket price level, namely the affordability of ticket prices, and the affordability of ticket prices plays a mediating role in the impact of the ticket price per person on perceived value. The mediation effect as a proportion of the total impact is first-tier cities(57.3%), new first-tier cities(45.2%), second-tier cities(40.2%).
