Outline of Final Research Achievements	This research project investigates the transformation of the colonial trade to capture how the interdependent structure of economies in the metropole and colonies was formed in Japan before the Second World War. The previous literature on the Japanese colonial trade and economy did not reveal the following two points: (1) a cyclical structure that the expansion of colonial trade and the transformation of commodity markets mutually affected each other in Japan and its colonies, (2) dynamic transformation process of the network structure of the Japanese colonial trade. Consequently, it did not demonstrate why the colonies supplied primary commodities to the metropole in Japan before the Second World War. This supply of primary commodities promoted the rapid growth in the Japanese economy. Therefore, we examined the reason of an increase in the Japanese colonial trade.

Academic Significance and Societal Importance of the Research Achievements	本研究は，近代日本の経済成長メカニズムを植民地領有との関連から捉え直す試みである。戦前期日本は台湾，朝鮮，「満洲」を植民地とし，食料・原燃料に用いられる1次産品の供給源として利用した。それら植民地産1次産品は日本内地の経済成長を根底から支えた。例えば，植民地産食料の供給増加は内地における非農業部門の労働供給拡大を支えた。しかし，日本植民地経済史の既往研究は，各植民地内における個別資本の動向に着目し，植民地経済拡大が内地経済の成長に及ぼした規定性は視野に収めてこなかった。そこで，本研究は内地・植民地経済間の相互規定的な関係性に着目し，米穀市場など食料市場の事例から上記関係性を解明した。
