Abstract: In recent years, the objective of research of “college students identity” is vague, the research lacks the depth exploration of students' social communication and neglects their field, habitus and position inherited from family. In this paper, the comprehensive, personal and spontaneous development is treated as the starting point and final destination of the research, their specific social field, self capital and habitus, and the differences and characteristics of their social position should be paid attention to, thereby the theoretical research can be in depth.
