The bottom line of social security policy should be strengthened to ensure the basic people’s livelihood. The minimum wage system，the unemployment insurance system，and the minimum living security system are powerful tools for the maintenance of labors’ rights and interests，social security for the unemployed，and social assistance for the poor. Comparing the relationship between the three standards in the past ten years，and based on the differences and commonalities of the three systems，the paper discusses a reasonable proportional relationship between the three，and provides recommendations for policy adjustment.
