The impact of overqualification on the intention of urban withdrawal from the perspective of talent crowding

Talent agglomeration greatly promotes the development of cities as a special form of talent allocation. However, excessive agglomeration of talent also leads to talent crowding and overqualification, which undermines the effectiveness of employing human resources and stimulates talent urban withdrawal. Based on the data from 327 questionnaires, data analysis was performed using Mplus 8.0 and HLM 6.08, this study explores the internal mechanism between overqualification and talent's intention of urban withdrawal from the perspective of talent crowding. The following conclusions were drawn: (1) Overqualification is positively correlated with talents' intention of urban withdrawal. (2) Psychological contract breach plays a mediating effect between overqualification and the talents' intention of urban withdrawal. (3) Relational mobility is negatively correlated with talents' intention of urban withdrawal. (4) Relational mobility plays a moderating role in the relationship between overqualification and talents' intention of urban withdrawal. (5) Urban livability is negatively correlated with talents' intention of urban withdrawal. (6) Urban livability plays a moderating role in the relationship between overqualification and talents' intention of urban withdrawal. The results can further improve the human resource management theory and serve as a foundation for developing and implementing population management policies in cities.
