日本在明治初期將移民列爲重要國策,有計畫的將日人進行國內外移民,20世紀初到1945年,日本在殖民地的移民尤其顯現其帝國擴張色彩。在日本眾多移民地當中,本文選擇臺灣與滿洲作爲討論對象的原因有下列幾點;1.日本在臺灣的移民事業,爲日本帝國第一次殖民地移民,臺灣的經驗曾作爲其他殖民地的參考。2.日本在滿洲帶有武裝性質的移民,人數之多,分佈之廣,居日本帝國圈之首。3.臺灣與滿洲在日本帝國的大陸政策上,分別具有南進基地與北進基地的重要性。由於兼論日本在滿洲與臺灣的移民範圍過於龐雜,本文聚焦於同屬國策會社的臺灣拓殖株氏會社和滿洲拓植公社,探討移民事業的開展與日本國策的關係,並說明臺拓在南進政策、滿拓在北進政策所扮演的角色,試圖分析國策會社的移民事業與日本帝國擴張的關係。
