Contemporary Taiwanese literature has been developing for 100 years if dated back to 1920. The historical context brought by multiple colonial periods and immigrants has made Taiwan nativist literature, which occupied more than half of the development period, develop a correlation generated from nativist literature to locality in Taiwan, and then the correlation was linked to the Taiwanese national consciousness. Scholars who support the Taiwanese localization movement attach national character to Taiwanese literature in an attempt to shape it into the literary tradition of the "Taiwanese nation".However, the postcolonial discourse in Taiwan with the introduction of globalization and western theories in recent years has cause many people to waver in the concept of locality. The Taiwanese literary tradition of 100 years mixed with the paradox of heterogeneity in consciousness is now difficult to explained by the Taiwanese National Literary Theory. Upon observing this phenomenon, the literary boundary concept of the "sense of land commonality" was suggested in the study based on More on the Subject as Void by Chao-Yang Liao. The concepts of "Taiwaneseness in Taiwanese literature" proposed by Kuei-Fen Chiu and Political Unconscious by Fredric Jameson were both referred, and the discussion of the literary criticism and discourse on "land unconscious" was raised. It is expected that the concept of "land unconscious" can be applied to the reading of text in order to obtain the semantic variety of "then, multi-party and here". Due to the length limit, no further description or comparison of events in literary history was in the study, and the main idea of it was to discuss a possibility in literary studies.
