Abstract: The belief in social mobility is a powerful endogenous driving force for adolescents from out-of-poverty families to strive upward,create a better life and realize the value of life. It is also an important foundation for rural revitalization and common prosperity in China. The aim of this study is to strengthen and enhance the social mobility belief of adolescents from out-of-poverty families in China. By reviewing the latest literature both at home and abroad,this study introduces the connotation and characteristics of the social mobility belief,systematically sorts out the positive role of the social mobility belief in promoting individual development,and puts forward the protective role of the social mobility belief in coping with various potential risks. Besides,the dynamic mechanism of the social mobility belief is discussed from the perspective of growth mindset and identity theory. To stimulate the social mobility belief and exert its important function to promote the development of teenagers form out-of-poverty families,there are several key steps we need to take. First,we should focus on a variety of effective methods to improve adolescents' social mobility belief including optimizing the coordinated development of the society and family;Second,we should adhere to the comprehensive promotion of “ambition” and “intelligence” to integrate the social mobility belief and coping strategies (or skills) as a double-drive development model;and the third,we need to prevent the negative effects of the potential “double-edged sword” of the social mobility belief in advance.

Key words: adolescents in poverty, the socioeconomic status of families, the belief in social mobility, rural revitalization
