A total of 287 thousand m3 local Sugi logs from Miyazaki and Kagoshima Prefectures are exported from Shibushi port to China annually. This study measured the economic ripple effects of log exports by creating a Miyazaki-Kagoshima-other 45 prefecture interregional input-output table. Supposing final demand for log export is 3,566 million yen, which was the annual log export from Shibushi port in 2017, induced production values are 2,936 million yen in Miyazaki Prefecture, 2,507 million yen in Kagoshima Prefecture, and 1,425 million yen in other prefectures. Induced added-values are 1,817 million yen in Miyazaki Prefecture, 1,417 million yen in Kagoshima Prefecture, and 611 million yen in other prefectures. The number of gross induced jobs is 81.4 in Miyazaki Prefecture, and 79.4 in Kagoshima Prefecture. Additionally, business model transfer from Sugi log exports to Sugi product exports would make the gross regional production 2.9 times larger in Miyazaki Prefecture and 2.0 times larger in Kagoshima Prefecture. As a future wood export strategy, we suggest the importance of transforming to Sugi product exports.
