This paper focuses on the disadvantaged group of low-income group, and based on a perspective combining urban geography with urban sociology and using residents in lowincome neighborhood as representatives of low-income group, it analyzes the commuting activity characteristics, internal variations, and influencing factors of low-income group under the background of urban social space differentiation and urban structure restructuring. The paper takes Kunming as the sample city, and uses the method of questionnaire survey to conduct a quantitative analysis on commuting activities of residents in three types of low-income neighborhood, which are urban village, indemnificatory housing(including low-rent, public rent, and economically affordable housing), and residential area of declined factories. The study shows that not only apparent variations on commuting activities exist among low-income group in different types of neighborhood and with different jobs, but also the influencing factors are different from regular citizens. The study provides a foundation for further exploration on issues like employment barrier for disadvantaged group and separation of their residential space.
