Abstract: New generation of migrant workers play an important role to economic transformation, and their social security rights and interests directly affect their survival and development. Through an investigation of 328 new generation workers in Suzhou, this paper found there is still a large gap between their desire and the current situation. The imperfect social security system, social security pattern differences between regions, enterprises’ irresponsible behavior and the subjective factors of new generation of migrant workers, all exert influence in new generation of migrant workers’ social security rights and interests. Therefore, the nation, governments, enterprises and individuals all need to shoulder the responsibility and work closely together to make new generation of migrant workers’ rights and interests complete and inviolable.
