The coupling and mutual feedback between subway accessibility and commercial facilities is one of the important prerequisites for promoting the coordinated development of cities. This paper uses spatial syntax to measure the accessibility of Xi'an subway, and combines GIS kernel density analysis and bivariate spatial autocorrelation analysis to explore the spatial distribution of subway accessibility and commercial facilities, as well as the coupling and spatial structure between them. The study found that: 1)Subway accessibility presents the characteristics of multi-center spatial layout, and has spatial imbalance. 2)The commercial facilities present a center-periphery spatial layout, with the bell tower as the center and the core density gradually decreasing to the surrounding areas. 3)From the perspective of spatial correlation, the subway accessibility and the layout of commercial facilities have a high spatial correlation. The local spatial pattern is relatively stable. The High-High and Low-Low aggregation areas constitute the main spatial correlation mode, and the distribution proportion of High-Low and Low-High types is relatively low.
