Since industrialization migration has been a continuous phenomenon, it invigorates innovations and technologies. Due to this reason, several research questions aroused that either the migration has any causal effect on employment opportunities for native people from global developed economies. Moreover, the role of migration affects the national income of the economies due to internal mobility and expansion of the cities. An instrumental variable model with a fixed effect is used to analyse the data. The study has used twenty years annual data set start from 2000 to 2019. The data have taken from World Development Indicator (WDI) and the Organization for Economic Co-operation and Development (OECD). The results explore that employment opportunities at the individual level are affected by the presence of a foreign workforce. Moreover, migrant population pressure could be a possible reason for the decrease in available work opportunities for the native labour force. However, the national income does not get affect by the incursion of migrants from outward boundaries of the international cities. The overall findings of this study concluded that global migration matters seriously but at the individual level and particular kinds of work opportunities have stressed due to immigration, but the overall impact is subtle.

全球移民重要吗？十大城市迁移对本地国民收入和就业水平的影响

由于工业化迁移是一个持续的现象，它激发了创新和技术。由于这个原因，一些研究问题引起了移民对来自全球发达经济体的本地人的就业机会有任何因果影响。此外，由于内部流动和城市扩张，移民的作用会影响经济体的国民收入。使用具有固定效应的工具变量模型来分析数据。该研究使用了从 2000 年到 2019 年的二十年年度数据集。数据来自世界发展指标 (WDI) 和经济合作与发展组织 (OECD)。结果表明，个人层面的就业机会受到外国劳动力的影响。而且，移民人口压力可能是本地劳动力可用工作机会减少的一个可能原因。然而，国民收入并没有受到来自国际城市外边界移民的影响。这项研究的总体结果得出结论，全球移民问题很严重，但在个人层面和特定种类的工作机会因移民而受到压力，但总体影响是微妙的。
