The Impact Of Social Security On Rural Migrant Workers' Household Living Consumption In The City

The total number of Chinese migrant workers reached 281,710 thousand in 2015,among of which are 16934 thousand migrant workers who leave their home.Although the large group of migrant workers have made important contributions to the development of the city,the quality of their life in the city is not high,which mainly manifested in the low-level consumption and poor living conditions.Food,clothing,fitness and other personal consumption is investment in personal health,the low-level consumption and poor living conditions will lead to the migrant workers' physical and mental health are damaged.As an important part of human capital of migrant workers,the decrease of health capital will lead to the decline of human capital,which not only affect the long-term development of migrant workers,but also affect the human capital sustainable supply from migrant workers.Study on the impact of social security on migrant workers' urban living consumption may provide some policy basis of improving the social security system,cultivating consumption ability and expanding consumption demand of migrant workers,which not only improve the level of life and human capital of migrant workers in cities and promote the level citizenization,but also reduce the gap between rich and poor,realizing social equity and promote the progress of building a harmonious society.The main contents of this paper as follows,(1)Construct a theoretical analysis framework of the social security-impact on the household consumption of migrant workers;(2)The empirical analysis of social security impact on the household consumption of migrant workers.Based on the survey data of migrant workers in Liaoning Province,constructing OLS regression,analyze the impact of social security on migrant workers'consumption level of urban life,use Heckman two step method and Treatment-Effect method to correct endogeneity problem caused by social security variable's autoselction bias.Finally,using all samples and the sample who not migrant their whole family to the city to robustness check.(3)The empirical analysis of the social security impact on household consumption decision-making mechanism and the decomposion the total variance of consumption.Quantile regression method is used to study the effect of social security on the consumption of urban households in different levels.Counterfactual analysis and quantile decomposition are used to decompose the total variance of consumption at different levels,then analyze the difference between family characteristics effect and consumption elasticity coefficient at different level.The results show that,(1)The proportion of migrant workers' social security participation is not high and there is still much room for improvement.The annual per capita consumption of social security families is greater than that of non social security families,no matter it is family migration or non family migration sample.(2)There is a significant impact of social security on promoting the migrant workers urban household consumption,which still right after endogenous treatment and robustness test.(3)There is a big difference between migrant workers families with social security and non social security,but the change is basically identical,both of them first decline and then rise with the increase of the quantile of consumer spending.(4)There is a significant difference in households' consumption decisions between the families with social security and non social security,which is mainly manifested that there are significant difference in the impact of per capita income,per capita area,householder age and per capita years of schooling on household consumption between the families with social security and non social security.(5)After the decomposition of consumption differences on each quantile,the result shows that the total household consumption differences of two types of families decreases with the increase of the quantile,and the family characteristic effect of family is the main reason for the household consumption difference.Finally,combined with the above conclusions,this research can provide policy recommendations for the government and enterprises in better establishing and perfecting Urban social security system,and improving the level of migrant workers' living consumption.
