基于“中国农村劳动力转移就业社会政策研究”课题组的大规模问卷调查,本文着重考虑养老、医疗和工伤三大社会保险,并运用Probit模型,对影响农民工参与社会保障体系的相关因素进行了剖析。结果显示,农民工参与社会保障的情况更多受其企业性质和岗位特征的影响,但教育水平和认知状况等个体因素也具有重要作用。因此,鉴于农民工群体在就业、社保需求和缴费能力等方面的异质性和复杂性,在政策制定的过程中,需要充分考虑目标群体的意愿、需求和能力,探索出一套有中国特色的社会保障体系。 Based on the large-scale questionnaire survey conducted by the Research Group of Rural Labor Force Transfer and Employment in China, this paper focuses on the three major social insurances of endowment insurance, medical insurance and injury insurance, and uses the Probit model to analyze the related factors that affect the participation of migrant workers in the social security system Analyzed. The results show that the participation of migrant workers in social security is more influenced by the nature of their businesses and the characteristics of jobs. However, individual factors such as educational level and cognitive status also play an important role. Therefore, in view of the heterogeneity and complexity of migrant workers’ groups in terms of employment, social security demand and payment ability, etc., we must fully consider the wishes, needs and abilities of target groups in the process of policy making and explore a set of policies with Chinese characteristics Social security system.
