Abstract: The new generation of migrant workers' wage rights protection shows the structural change of legitimacy support,from the gradual expansion of survival right to the development right.Their willingness to act and ways of defending their rights mainly depend on the situation of labor market occupation and the embedding of urban social relations.Due to the worrying situation of those temporarily employed,their helpless relief and the grey traps they have fallen in,their wage actions have become normal.It is the first choice for migrant workers to have a job and obtain a better income.At present,the institutional channel of rights relief is crowded and the potential cost is not low,so the convergent power of informal rural relationship network should not be underestimated.It is necessary that the flexible and stable long-term employment mechanism should be established,the multi-party litigation organizations participated by employers,migrant workers and the government be formed,and the system of labor laws and regulations be perfected to fill the gap.In this way,the adaptability and anti-risk capacity of the new generation of migrant workers in the city can be greatly improved.

Key words: wage actions and right protection, structure, evolution, new generation of migrant workers
