Chiao-Tzu-Tou Sugar Factory ( originally named Kaohsiung Sugar Factory or Chiao-Tou Sugar Factory ) was the first new-type sugar factory in Taiwan. Sugar production was stalled in 2000, and most parts of the factory are currently unemployed. Taiwan Sugar Corporation has been planning to develop it into a "sugar cultural park—on-site museum". Based on on-site investigations, interviews, and the analysis on the historic traces and development of the sugar factory, this study aimed to establish the "space authenticity" of Chiao-Tzu-Tou Sugar Factory as a reference of further development and re-use of the space in the historic preservation area. It was expected to represent the co-existence of a Taiwan's new-type sugar plant and the urban environments
