It showed that the migration of rural labor force was still far away from ＂Lewis turning point＂, and ＂mingong huang＂ （ shortage of peasant workforce） appearing in coastal areas could be explained with the location separation between the labor-intensive industries and rural labor force. It was a feasible and an effective way to push forward the transfer of labor-intensive industries from the east coast to central and Western China to absorb the abundant supply of rural labor force.展开更多
