Theoretical Research on the Influence of International Labor Movement on the Domestic Inter-industrial Labor Movement and Unemployment of Different Generations

在本研究项目中，我们通过关注以下两点来考察国际劳动力流动对国内劳动力市场的影响。首先，我们研究了合法和非法的国际劳工流动(移民)问题，特别是非法移民的强制执行对失业经济的影响。第二，我们通过对发展中国家失业的研究，考察了发达国家产业间劳动力流动和失业的影响。也就是说，在发达国家被广泛观察到的许多兼职工人被认为是非正规部门的工人，发达国家工资低、没有吸引力的部门可能被发展中国家的农村农业部门取代，而发达国家年轻工人想要冒着失业风险就业的部门可以被视为城市制造业。在这方面，我们使用以前关于发展中国家失业的研究来研究年轻非熟练劳动力的失业问题。我们通过关注青年非熟练劳动力与中年熟练劳动力的区别，以及我国青年失业的特点，研究了减少失业、提高国民福利的各种政策。我们的分析得到了许多有趣的结果，例如，非熟练劳动力的流入可能会降低熟练劳动力的失业率，而熟练劳动力和非熟练劳动力的流入会增加各自劳动力的失业率。在运用贸易理论研究国际劳动力流动与国内劳动力市场运行的关系方面，我们似乎做出了一些贡献。

In this research project, we have conducted our research to investigate the effects of international labor movement on the domestic labor market by paying special attention on the following two points. First, we have studied the issue of legal and illegal international labor movement (immigration), especially the influence of the enforcement of illegal immigration for the economy with unemployment.Second, we have investigated the effects of inter-industrial labor movement and unemployment in 'developed' countries by applying the studies on unemployment in 'developing' countries. That is, many part-time workers observed extensively in developed countries are thought of workers in the informal sectors, the low wage unattractive sector in developed countries may be replaced with the rural agricultural sector in developing sector, and the sector that young workers want to be employed at the risk of unemployment in developed countries can be seen as the urban manufacturing sector. In this respect, we examine the issue of unemployment of young unskilled labor by using the previous studies on unemployment in developing countries. We have investigated various policies to reduce unemployment and improve national welfare by paying our attention on the difference between young unskilled labor and middle-aged skilled labor, and the characteristic feature of young unemployed in our country. That is, they are characterized as being voluntary because these workers have excessive expectations from their jobs and rely on others, especially the parents, for a living.Our analysis obtain many interesting results, for example, the inflow of unskilled labor may decrease unemployment of the skilled labor, though the inflow of skilled and unskilled labor increases the unemployment of respective labor. It seems that we have made some contributions to investigate the relation between international labor movement and the working of the domestic labor market by applying the trade theory.
