Global metropolises, including first-tier Chinese cities, are confronting unprecedented challenges of talent exodus amid escalating housing costs, competitive job markets and deteriorating urban living conditions. Traditional migration theories fall short in explaining young talents' mobility decisions, as their high human capital drives them to prioritize multidimensional considerations beyond mere economic returns. This study develops a comprehensive theoretical framework integrating multiple aspects of prospect theory—reference dependence, loss aversion, endowment effects and risk attitudes—to investigate young talents' settlement intentions through logistic regression analysis of survey data from 1065 professionals across Beijing, Shanghai, Shenzhen and Guangzhou. The research reveals that migration decisions are fundamentally shaped by asymmetric psychological evaluations: young talents demonstrate heightened sensitivity to potential losses in job prospects and housing affordability. Institutional and psychological endowments significantly enhance settlement intentions: homeownership, local hukou status and public sector employment increase staying probability, along with longer duration of residence and stronger place attachment. Notably, our findings reveal nuanced suppression effects of migration-specific risk attitude on one's general risk attitude: while first-tier cities attract individuals with higher general risk tolerance who are willing to embrace urban challenges, these individuals also tend to have higher migration-specific risk tolerance, which in turn reduces their long-term settlement intention. These insights not only advance behavioural economic understanding of talent mobility in urban areas, but also provide practical guidance for metropolitan governance. Our findings suggest that effective urban talent retention requires cities to strengthen institutional ties and guarantee stable career development rather than relying primarily on economic incentives. This approach ensures cities maintain the human capital essential for innovation and competitiveness in an era of increasing inter-urban competition.
