Perceived employability,defined as the individual perceived possibility of obtaining and maintaining one’s(current or future)employment,is an important personal resource that allows individuals to adapt to the increasingly uncertain workplace.From an enterprise point of view,however,high employability perception may stimulate high employee mobility,putting companies at risk of losing costs such as training and development.This paper systematically reviews the connotation,structure and measurement of the perceived employability,then studies the consequences of perceived employability and its inner mechanism from the perspectives of career management,occupational health psychology,and organizational behavior.To a certain extent,it helps us to clarify the differentiated effect and its internal mechanism of perceived employability on individuals and enterprises.
