Abstract:Since the Goryeo period, Korean literature absorbed much Chinese culture with Han culture and Confucian culture as its core and began to integrate into the East Asian culture, making its way to world literature. In modern times, it received Western culture and integrated into Western cultural system, realizing the modernization of Korean literature. Currently, in the globalization era, Korean literature is turning inward to its own cultural tradition for future development. The historical trajectory of the cross-border changes in Korean literature shows that Korean literature has been changing its cultural direction to keep up with the times in effort to integrate into various cultural systems to be part of world literature. Obviously, this is the result of the constant adjustment of Korean literature to meet changes and integrate into the mainstream world culture of different era. In this process, Korean literature has shown a distinctive trajectory and characteristics of sinicization, Westernization, and globalization. In the globalization era, Korean literature has begun to turn inward and return to its own culture, attaching importance to its national cultural tradition and showing distinctive Korean characteristics. Against this backdrop, Korean literature in recent years has shown the following characteristics: a distinct nationalization trend; reinterpretation of traditional culture to keep up with the times, and modern interpretation of traditional culture; various movements of modernity becoming the mainstream of Korean literature; the industrialization of literature and culture becoming a general trend for future development. All these are the results of the modern transformation of Korean literature based on national classics.
