Effect of socio-demographic characteristics on social security in northeast China.

Social security is the most important and even the only source of income for Chinese older people. It is an important guarantee for the medical care and living of older people. However, the backward economy may bring great hidden troubles to the social security of resource-exhausted cities in the future. Our aims were to explore effects of socio-demographic characteristics on social security in the resource-exhausted city. We set up panel data models for social security contributions, social security benefits, newly insured individuals and ex-insured individuals, respectively, to track changes in social security of different age, genders and workplaces from 2011 to 2015. There were 175,194 individuals who eventually entered our database. We found that individuals working in enterprises and individuals aged 55 to 60 had relatively less social security contributions and more social security benefits. Individuals under 25 years of age were more willing to participate in social security. Individuals working in enterprises and men were likely to withdraw from social security. We have concluded that there are some problems that cannot be ignored in the social security of resource-exhausted cities. Our research makes a certain contribution to better guaranteeing the life of older people and improving their qualities of life in resource-exhausted cities.
