What is the significance of studying the social security of migrant workers?

Migrant workers are a group different from farmers and between farmers and citizens, and they are industrial workers with the status of farmers. They have made great contributions to the prosperity and development of the city, but due to the "dual structure" between urban and rural areas formed under the planned economy system for a long time and its inherent economic and social system, migrant workers wander between the city and the countryside. The legitimate rights and interests of migrant workers can not be effectively guaranteed, and the resulting social security problem has become an urgent problem in the construction of China's social security system. Therefore, it is of great significance to study the social security of migrant workers for improving their social security system and self-protection.
