日本農業移民不但是台灣拓墾史上相當獨特的移民型態，在日本移民史亦有其獨特的地位；一方面是日本向來鼓勵移民之國策的體現，一方面也是日本內在社會因素和國際政治交相作用的結果。北海道的移民屬於國內移民，台灣則為殖民地移民，兩者在自然環境、移民性質和實施的時間上都有其差別，基於兩者的異質性，所以本文的重點不在日本移民北海道與移民台灣的比較，而在探討北海道的拓殖移民經驗如何應用到台灣。本論文以北海道拓殖移民為基點，來看日本從事新領土開發的過程，以及北海道拓殖對台灣的農業移民的影響和作用。另外，移民的職業雖然包括農業、漁業、工業、礦業等類，但是不論在重要性與數量上都以農業移民居首，因此本文也只針對農業移民加以討論。

The Japanese government has been supporting both of the oversea and domestic agricultural immigration policy since the end of the 19(superscript th) century. The immigration to Taiwan that reflected the effects of the interplay of domestic social and international political affairs was very unique in the immigration history of Japan. The nature of oversea and domestic immigrations was heterogeneous though they occurred in the similar social and political context. The study will make an attempt to contrast the oversea colony, Taiwan, and the domestic, Hokkaido, agricultural immigrations. The specific objectives include: (1) an exploration of what a role of Sapporo Agriculture School played in the cultivation plan; (2) an examination of whether there were impacts on the immigration to Taiwan based on the Hokkaido's experience; and (3) an. investigation of what a role the Japanese government played in these issues in terms of planning and execution.
