The core issue of this research is to analyze food access, nutritional intake and food safety cognition level and their influencing factors among the migrants in China. Subsequently, we further make a comparative study and heterogeneity analysis from the flow direction (rural-to-urban and urban-to-urban migrants) and urban scale (regional central city Nanjing and its nearby prefecture-level city Changzhou).
Research Question 1: Considering the impact of rapid urbanization on food security, this study examines the basic situation and their influencing factors on food access and nutritional intake among rural-urban and urban-urban migrants, taking Nanjing, a regional central city and Changzhou prefecture-level city as examples.
Research Question 2: Based on the Urban-rural Dual Structure Theory and Big Food Concept, this study analyzes the cognition and utilization level of the floating population on food nutritional safety involving multiple dimensions, and explores the differences by using two sub-samples of rural-to-urban and urban-to-urban migrant.
Research Question 3: Combined with the background of the post-pandemic era, this study focuses on the changes and differences in income, job opportunities, food consumption expenditure and food safety cognition of rural-urban and urban-urban migrants before and after the pandemic.
