Abstract
ABSTRACT: Based on the data of “employment and food demand of urban migrant workers”, this paper empirically analyzed the impact of urban pension insurance on the nutritional intake structure of migrant workers. The results showed that participating in urban pension insurance can change the nutritional intake structure of migrant workers. Additionally, fat and protein replace carbohydrate as the main nutrition sources for migrant workers. After controlling the income and labor intensity of migrant workers and other factors, urban pension insurance has a positive effect on the intake of fat and protein of migrant workers for they increase by 13.5% and 8.8% respectively. There is no significant effect on the intake of carbohydrates of migrant workers. The calorie intake of migrant workers increases by 6.8% accounting for the change of nutritional intake structure. Endogenous and robustness tests showed that the above conclusions are robust. Heterogeneity analysis showed that there is no significant difference in the effect of urban pension insurance on calorie intake of migrant workers in different income levels and age groups.

Summary
China’s rural residents have been moving to cities and towns, gradually forming a special group of migrant workers. According to 2019 Statistical Bulletin on the National Economic and Social Development of China, In 2019, up to 291 million migrant workers accounted for 66% of urban employment. The social security level of migrant workers is far lower than that of urban workers (LI & LI, 2007). According to the 2017 Statistical Bulletin on human Resources and Social Security Development of China, in 2017, the participation rate of urban pension insurance for migrant workers is only 21.6%, compared with 17.0% in our paper’s sample. Migrant workers are faced with disadvantages such as lower income level, higher labor intensity and worse working environment. With the increase of working hours, the health status of migrant workers is gradually worse than that of urban residents
