30年代臺灣地區是一個政治、經濟多變的社會，歷經日本統治、戰亂、光復與政 府遷臺等變動。為瞭解 30 年代臺灣地區的經濟變化，本研究致力編算民國 26 年至 39 年 臺灣地區國內生產毛額。依估算結果，民國 26 年平均每人實質國內生產毛額折算約新臺幣 1,977 元，至 30 年均呈小幅變動；太平洋戰爭時期逐年下降，至 34 年僅 679 年； 戰後 隨復建及產業發展，逐年增加，至 40 年為 1,493 元。 民國 27 年至 30 年平均經濟成長 率為負 0.7 ％；太平洋戰爭期間逐年下降，致 31 年至 34 年平均為負 18.7 ％； 光復後 至 40 年平均經濟成長 17.6 ％。

　　　　　Politically and economically, Taiwan suffered bitterly in the 1930s and 1940s. Important events during this period included war chaos, retrocession, and the central government's move to Taiwan. To further our understanding of the economic change that occurred in Taiwan during this period, this study calculates Gross Domestic Product (GDP) in Taiwan from 1937 to 1951. Real GDP per capita averaged NT$1,977 in 1937. This fell moderately through 1941 and then decreased to NT$679 during the Pacific War. By 1951, it had recovered to NT$1,493 due to post-war industrial development. Economic growth averaged-0.7% from 1938 to 1941, -18.7% from 1942 to 1945 and 17.6% from the year of retrocession to 1951.
