Abstract: In the era of globalization，marketization，and network，boundary has not been eliminated；instead，its cultural significance is more manifest. In geography，there is the separation of cultural boundary in living space，the identification of cultural boundary in identity symbols，and the interaction of cultural boundary in geographical communication. In politics，there is the demand of cultural boundary in democratic development，the regulation of cultural boundary in the exercise of rights，and the demand of cultural border defense in border security. In economics，there is the cultural boundary effect in economic development，the demarcation of cultural boundary in regional cooperation，and the form of cultural boundary in trans-cultural cooperation. The narratives of different disciplines on cultural boundary highlight the cultural turn of boundary，and the analysis is of great significance for deepening the cognition，enriching the connotation，and enhancing the construction of boundary.
