Abstract: Abstract The transportation infrastructure is a crucial component of social capital, as it aids in fostering national economic growth. The speed of resource elements’ spatial movement is increased by high-speed railways (HSR), thereby affecting the intensity and direction of regional economic connections. This study investigates how HSR impacts urban regional accessibility and the spatial spillover of urban residents’ income from a spatial viewpoint. The study found that: First, between 2000 and 2018, the introduction and functioning of HSR, along with the increased speed of regular railway services, led to an overall enhancement in urban regional accessibility and urban positioning. Second, there exists a notable spatial correlation between regional accessibility and labor market income. Cities with either high or low labor market income exhibit spatial clustering in the same direction at the spatial level. Enhancing regional accessibility typically leads to an increase in labor market income throughout the entire region. Third, the nearby cities with greater regional accessibility exert a siphon effect on the local area. Fourth, the labor market income is interdependent and promoted among cities. The labor market income of a city is positively influenced by the nearby cities and neighboring cities with comparable income levels. Fifth, between 2012 and 2018, the construction of HSR and the structural transformation of the labor market led to a notable increase in income through a positive spatial spillover effect.
