By 1905 Taiwan was fully economically independent and self-sufficient, no longer having to rely on assistance from Japan. Two years later, tax on sugar and trade tariffs began being paid into Japan's coffers, and the territory transformed from being an annoyance to a valuable asset. The government began to consider Taiwan a valuable addition to the empire.
到了 1905 年，台灣的財政已能獨立自給，不再需要仰賴日本補助，兩年後更以關稅與砂糖消費稅「回饋」日本，台灣由「負債」變成「資產」，日本才逐漸視台灣為寶庫。
