Taiwan's publishing market is so small (it is worth only about NT $ 30 billion per year) and its subject matter so limited that even a popular book by a local writer is lucky to sell more than 50,000 copies. Such numbers don't even begin to compare to more than NT $ 500 billion the Harry Potter franchise has generated worldwide since 1997, or the million-plus volumes The Da Vinci Code has sold.
台灣書市規模太小（一年約新台幣 300 億元）、題材侷限，市場大餅分食下，再熱門的本土創作書都很難賣超過 5 萬本，相較於歐美《哈利波特》（1997 年以來，「哈利波特工業」的全球產值約 5,000 億台幣）、《達文西密碼》這樣動輒百萬本的暢銷書，簡直無可比擬。
