Sugar was one of the most important products in Taiwan during Japanese colonial period. This paper estimates the production values of sugar and cane in Taiwan between 1901 and 1953. The value-added of sugar is also estimated. Compared to previous studies, this paper explores much more raw data. We also estimate the sugar tax and compute the pre-tax production value of sugar. This research is a part of our project to re-estimate Taiwan's GDP. Our estimates cover up to 1953 in order to link with the post-war national accounts.
