This paper treats the ”Taiwan consciousness” that emerged in the middle of the period of Japanese rule as a kind of nationalism. Based on Benedict Anderson’s theory of ”imagined community,” together with Marshall McLuhan’s theory of ”media,” the author considers that Taiwan consciousness could have been arisen with the emergence of type-print literature by analyzing texts advocating literature in the newspaper ”Taiwan Ming-Bao” from the 1920s to the 1930s. It is argued that the abstract conceptof the ”Taiwan people” was first claimed because the newspaper authors were aware of the capability of typeset print and then appealed to the nonspecificmasses, instead of familiar friends, as their readers. At thebeginning, the term ”Taiwan people” to oppose the Japanese was not distinguishable from that of China. Afterwards, starting from the late 1920s, a clearer boundary between Taiwan and China was drawn in the presssponsored literature contests. That is to say, the Taiwanese nationalismconcerning the ”3.6 million people of our Taiwan” took shape as an imagined community according to Anderson’s theoretical meaning. Thus, the development of typographic printing should be understood as the keymechanism to the modernist construction of Taiwan consciousness.
