The study found that: 1) labor contract and labor union contribute to the acquisition of the workers’ social security right, and the promotion of labor contract is greater than that of labor union; 2) the impact of labor contract and labor union on different types of social insurance is also different, which is more reflected in the unemployment insurance and basic medical insurance, while less reflected in the work injury insurance.en-USLabor ContractLabor Contract, Labor Union, Social Security Right, Basic Endowment Insurance,Labor UnionSocial Security RightBasic Endowment InsuranceArticle
