Two-step floating catchment area analysis is popular for measuring the spatial accessibility to health care, and many enhanced two-step floating catchment area methods have been proposed in order to get a more realistic result. However, the multiple transportation modes need to be explored further. Beijing is a metropolis with premium medical resources and convenient public transportation, it is a typical region to explore how different transportation modes effect the spatial accessibility to tertiary hospitals. Based on the enhanced multi-modal two-step floating catchment area analysis and the statistical data on travel time by public transportation and driving, this paper analyzes the spatial accessibility to tertiary hospitals in Central Beijing in multiple scenarios. The results indicate that the spatial accessibility to tertiary hospitals of the sub-districts in Central Beijing is sensitive to different transportation mode, but the spatial patterns still correspond to the Ring Structure. The spatial accessibility scores of the sub-districts near the city center are high, the scores of the sub-districts away from the city center are low, and the scores of middle regions are significantly influenced by the transportation modes. To balance the spatial distribution pattern of spatial accessibility to tertiary hospital, it is not only can locate the hospital more evenly and reasonably but also can improve the public transportation system in regions away from the city center.
