Abstract: Under the background of social stratification and intensification of the internal differentiation of migrant workers, is there any intergenerational difference in the impact of income level on the relative deprivation of migrant workers? Based on the analysis of China′s comprehensive social survey project data, Bootstrap mediation test method and structural model, this paper finds that, there is intergenerational difference in the impact of income level on workers′ relative deprivation; for the original migrant workers, the increase of income can significantly reduce economic deprivation and social deprivation, and social fairness plays mediating effect; for the new generation of migrant workers, the increase of income can reduce economic deprivation but cannot reduce their social deprivation significantly, and social fairness does not produce mediating effect.Therefore, It is necessary to consider the intergenerational differentiation in a reasonable guide to the transfer of labor on the township, and it is important to reduce migrant workers′ relative deprivation by measures of further increasing the source of income, entrepreneurial support, public service supply.

Key words: migrant workers, relative deprivation, social fairness, mediating effect
