Faced with the economic crisis in the 1970s，western countries began to review the “welfare trap” problem，reformed employment assistance system which adopted more active employment assistance policy，introduced market mechanisms and aroused social forces to participate in employment services，which promoted equity and efficiency of social welfare. These countries also established the assessment and monitoring mechanism to implement the refined management of employment assistance，so the mid and long-term effects emerged gradually. Currently，as the adjustment to China’s economic and social system structure，the structural unemployment issues become prominent. Therefore，foreign experience can be used for reference in the institutionalized and refined construction of employment assistance.
