Abstract: Based on the dynamic monitoring data of floating population from National Health and Family Planning Commission in 2013, this study conducts binary logistic regression to analyze the influencing factors for urban-to-urban migrant population on the endowment insurance participation. The results show that personal characteristics, such as gender, age and education, are closely related to the enrollment. Males and people aged from 25 to 34 and with higher education are more likely to participate. Employer type, income and housing situation are most important economic and social factors that influence the endowment insurance participation of the floating population. Migrants working in foreign invested enterprises are most likely to participate. Those with high income or possessing their own houses are also more likely to enroll. Types of destination, duration and distance also have significant impact on the participation behavior. The floating population in central China has lower rate of enrollment than those in east and west China. The cross-county migrants are more willing to attend than the cross-city and cross-province ones. The longer the migrants stay, the higher the probability of participation is.

摘要： 文章使用2013年国家卫计委流动人口动态监测数据，采用二分类Logistic回归分析方法，分析城-城流动人口参加养老保险的影响因素。研究发现：第一，个人特征方面，性别、年龄、受教育程度与参保行为显著相关，男性相比女性参保率较高；25～34岁组参保可能性最大；受教育程度越高，参保可能性越大。第二，经济社会因素中，单位性质为外资企业的流动人口参保可能性最大；收入越高，参保率越高；拥有商品房或自建房的相对于租住私房的参保率更高。第三，流动因素中，流入区域、时间和流动范围对参保行为影响显著，中部相对于东部、西部参保可能性最小；市内跨县流动者相对于省内跨市、跨省流动者参保可能性更大；流入时间越长参保可能性越大。
