本文所探討的是工作、求學、或家庭因素遷移到新加坡及香港的臺灣年輕人。以2011-2014年在新加坡、香港及臺灣所進行的40個深度訪談為基礎，進一步獲得對受訪者及當地環境的詳細資訊與深入瞭解。本文首先回顧年輕移民、青年人才、及從臺灣移出的1.5代移民的相關文獻，隨後，本文將新加坡與香港的臺灣年輕人依以下幾個重點分類，並且進行訪談分析：（1）遷移到新加坡或香港的原因、（2）移動類型與移動軌跡、（3）社會與文化適應、（4）返回臺灣的意願。除了更高的薪資與福利之外，新加坡與香港提供給他們的是一個與全球接軌的國際化環境與個人發展的舞臺。然而，居住在新加坡與香港也有一些缺點，例如：語言、氣候、文化差異、生活成本高、生活品質等。這群臺灣年輕人的流動不僅對新加坡與香港所競逐的全球人才有所貢獻，海外的經驗也有助於他們發展適應不同社會文化環境的能力。在這關鍵時刻，臺灣有關招募全球青年人才的政策，仍然處於岌岌可危的情況。我們迫切需要相關政策的制訂，為的是防止接受過良好教育的專業人才離開臺灣，並且透過更完善有效率的政策，吸引這群人才有意願返回臺灣。由於臺灣年輕人在移動上的暫時性質，臺灣政府可以開發這類人力資源，作為競逐全球人才的一種策略，並且作為人口政策與社會轉型的重要一環。

This paper studies young Taiwanese who migrated to Singapore and Hong Kong for work, study or family reasons. It is based mainly on 40 in-depth interviews conducted in Singapore, Hong Kong, and Taiwan in 2011-2014, thus obtaining narratives that contain detailed information to render nuanced understanding of the interviewees and the environment. The paper begins with a review of pertinent literature that includes youth migration and global talent, and the 1.5 generation migrants from Taiwan. It is followed by an analysis of major types of young Taiwanese in Singapore and Hong Kong with regard to: (1) their reasons for moving to Singapore or Hong Kong, (2) the types and trajectories of movement, (3) their social and cultural adaptation, and (4) prospects of returning to Taiwan. Apart from the higher pay and fringe benefits, both Singapore and Hong Kong provide them with a cosmopolitan environment for global pursuits to which their education applies. However, there are disadvantages of living in Singapore and Hong Kong, such as climate, social and cultural differences, high cost of living, and quality of life. Being highly educated, they have contributed to the pool of global talents that both states compete for, while gaining overseas experiences in enhancing their skills and exposure to new social and cultural environments. At this juncture, Taiwan's policy to recruit young global talents remains at stake, and the urgent need is to prevent its well educated professionals from leaving, as well as to attract them back with more vigorous and effective polices. Due to the impermanent nature of young Taiwanese on the move, Taiwan may want to tap this human resource as a strategy to compete for global talents, as a critical aspect of population policy and social transformation.
