Do languages matter? The impact of local dialect proficiency on multidimensional poverty alleviation among rural-to-urban migrants in China

Language plays a crucial role in poverty among migrants. However, the relationship between language skills and poverty among internal migrants in developing countries has received limited attention. Using data from 11,789 rural-to-urban (RTU) migrants in the China Migrants Dynamic Survey, this study empirically assesses the impact of local dialect proficiency (LDP) on multidimensional poverty alleviation among migrants and further investigates potential mediators of this association. The results indicate that enhanced LDP significantly reduces the prevalence of multidimensional poverty among RTU migrants, with speaking proficiency having a more significant effect than listening proficiency. Moreover, three key mechanisms contribute to multidimensional poverty alleviation through LDP: the expansion of social networks, enhancement of urban identity, and improvement of employment quality. Heterogeneity analyses reveal that the impact of LDP on multidimensional poverty alleviation is more significant in regions characterized by higher dialect diversity and lower popularity of Mandarin, as well as among males, older generations, and RTU migrants with lower levels of education. In conclusion, this study advances understanding of the role of language proficiency in poverty alleviation among migrants by constructing a cultural-linguistic theoretical framework.
