Abstract: Based on national representative survey data from the National Health and Family Planning Commission of China in December 2010, this paper examines the participation rate and determinants of social insurance of migrant populaiton in China’s urban regions. The findings show that training and education enhance the probability of enrollment of social insurance. The enterprise ownership and labor contract affect the probability of participation. The enrollment rate of rural-urban migrant is lower than that of the urban-urban migrant, and the participation rate of migrant in central China is lower than that of the eastern and western China. The results imply that migrant population is no longer passive recipients of social insurance, they have been some initiative. For the policy implications of expanding social insurance coverage of migrant population, training and education should be strengthened. In addition, the New Labor Contract Law should be seriously implemented. The rural-urban migrant population and central China should be taken as the key objectives for the coverage expansion.
