Urban rail transit has been rapidly developing in China. TOD development mode has further led the wave of integrated development of rail transit over recent years, creating a number of urban rail micro centers with intensive land, diversified functions and convenient environment, which fully illustrated the concept of “Rail transit leads the city development.” Based on the rail transit integration project of Suzhou Street Station in Haidian District of Beijing, this study analyzed five types of issues ahead of it: site, mode, function, construction period, and fund. The innovation mode of rail transit integrated development has been researched and proposed to combine several lands and achieve multiple functions that coordinate and utilize the relevant policies such as “one-off bidding” of shanty town reconstruction. The project effectively promoted subway construction, solved historical problems, saved subway investment, and met the needs of residents. It has achieved remarkable results in economy, society, and practice, reaching a win-win situation for the government, enterprises, and citizens, which can provide a reference for the subsequent construction of similar rail transit projects.
