How to improve employment ability of new generation migrant workers is the central part of improving living of migrant workers and development environment. Based on survey data of 6 counties in Hubei Province,I analyzed employment will and influence factors of new generation migrant workers. Researches have indicated that going out to work,employment opportunity,nature of subordinate service industry,industrial technical level,and financial support play a significant role in employment intention of migrant workers,while their employment ability is influenced by their cultural quality,professional skills, working endurance,degree of policy cognition,and information channel,etc. In view of these five aspects,I put forward following countermeasures: raise educational level,improve skills,strengthen endurance,enhance attention to policies,and expand information channel,to improve employment ability of new generation migrant workers.展开更多

The present paper comprehensively explores the profiles of the new generation of migrant workers in urban China. We find that the "new generation" migrants are more educated and skilled, and are likely to work in manufacturing and service industries than in the construction industry. Moreover, they tend to allocate more time to non-farm activities and have more months away from home per year in urban areas. In contrast to their predecessors, they tend to migrate to urban areas with their spouses, consume more in urban areas and send less money back home. Our findings suggest that the differences in features between the new generation of rural migrants and urban residents have become smaller and the integration of rural migrants into urban China has taken place gradually.展开更多
