Deer hunting and deerskin trade had been topics of research ever since the Japanese colonial era. However, with the changes in political power and regimes, different perspectives had been adopted. Ts'ao Yung ho's study on deerskin trade in early modern Taiwan is considered the first scholarly investigation on such issue in Taiwan. Though published in 2011, the research manuscript written by Ts'ao Yung ho dated back to the 1950s. The main purpose of this critical study is to analyze the development of research on deerskin trade and compare the various perspectives adopted by scholars of different nationality and in different eras. In particular, this critical study contains a review of Ts'ao Yung ho's publication Chin-shi Taiwan Lu-pi Mau-i Khau to examine whether this past research has any inspiration for further study on this issue.
