本文採推一拉理論的觀點來檢視戰前日人與華人遷徒台灣的情形。37年的戶籍統計資料用來檢討遷徒的數量、效率與選擇性。結果發現日人的遷徒量遠大於華人，主因是華人的遷入受到政策性的巖格控制。另外，也發現日人與華人之遷徒效率都低。再者，性別與年齡組成的選擇性使得日人與華人的遷徒人口呈不同的成長型態。

This paper reviews Japanese and Chinese migration to Taiwan in the pre-war period from the perspective of push-pull theory. Household registration data for 37 years are used to examine the volume, efficiency and selectivity of migration. We have found that migration by Japanese was much greater than that by Chinese, mainly the result of severe restriction on Chinese immigrants. We have also found that migration efficiency for Japanese and Chinese was low. Finally, the selectivity of the sex and age compositions of the migrants led to differential population growth for Japanese and Chinese.
