This study analyzes the imagination of transnational boundaries in the diasporic imagination of the diaspora novel defecting from North Korea since 2000, understands the tragedy of the diaspora situation experienced by defectors and the tragedy of distorted capitalist environment, and tries to show the significance of literature representations about that. For this study, I would try to take advantage of trans-national literary theory and literary ecology. In post-industrialization and digital Culture, trans-national literary theory reflect the people live in countries that have not been born, their experience about social space and geographic space; multiple identities, wandering, and agony. Social Ecology criticize national systems and capitalism culture, search human's mean as nature objects and the conditions of human life. Rina, Baridagi, and Wild Rose represent critically third world refugee's experience about conditions of life distorted capitalism environment. In their novels, migrating identity of the other collapse the boundaries of national borders and re-conceptualize national identity. This point illustrates trans-nationality of transnational literature. Further, based on results of this study, I will be compared many studies in other East Asian countries about the diaspora novel defecting from North Korea and pay attention to the universal features of transnational literature in that novels.
