Analysing the heterogeneity in working conditions of migrant informal workers in China: a test of the WIEGO model of informal employment

This paper sheds light on the internal heterogeneity within the informal economy by examining the working conditions of migrant informal workers in China. It presents the first attempt to test the WIEGO model on the relationship between informality, income, poverty and gender. Based on 107,020 samples of informal workers from the 2017 China Migrants Dynamic Survey (CMDS), economic, social and occupational health components of working conditions of migrant informal workers in five employment-status tiers are analysed. The results show the significant heterogeneity within informal workers in terms of their income, working intensity, labour contracts, social security, union and community support. The relationships between the informal employment tiers and income, poverty and gender show a pattern that is not fully in line with the WIEGO model, suggesting the complexity and plurality of heterogeneities in informal employment. The paper concludes by calling for research on regional varieties of the heterogeneity in informal employment worldwide to better understand the unfolding of the inequality-informality nexus in specific contexts.
