“南明”不只是单纯的断代史概念，在概念的流变过程中，限于言说者的立场与目的，其“概念”内涵多次变换，变换背后隐含着彼时的时代气氛、社会价值导向与言说者的精神动向。抗战时期，面对家国之难，台静农以《民族英雄张苍水》为题呼应社会中的“南明热”，但充斥着党争与变节的“居今”体验又促使台静农通过频繁的文本“手术”对“南明”概念重新赋义。从“南明”到“晚明”再到“亡明”的概念变迁史，是台静农“大道多歧”现实经历的投影，也折射出台静农作为知识分子的身份焦虑与对历史复现的惶惶忧惧。因此，从概念史的角度发现并定格历史概念“南明”在文学中的显影时刻，方便理解作家创作时的叙事选择与技法结构，更有助于理解在动荡时期台静农等文人的精神旨归与思想脉动。

"Southern Ming"(Nanming) is more than a mere dynastic concept. In the course of its evolution, due to the speaker's stance and purpose, the connotation of "concept" changed many times, and behind the changes were implied the atmosphere of the times, the social value orientation, and the spiritual orientation of the speaker. During the War of Resistance against Japanese Aggression, facing the hardships of his family and the country, Tai Jingnong echoed the "Southern Ming fever" with the title "Zhang Cangshui, the National Hero". But Tai Jingnong's life experience, full of party disputes and betrayals, prompted him to redefine the concept of "Southern Ming" through frequent textual "surgeries". The conceptual evolution history from "Southern Ming" to "Late Ming" to "Demise of Ming" reflects Tai Jingnong's real-life experience of "divergent paths". It also reflects Tai Jingnong's identity anxiety as an intellectual and his fears about the reoccurrence of history. Therefore, the discovery and framing of the historical concept "Southern Ming" in literature from the perspective of conceptual history not only facilitates understanding the narrative choices and technique structures of the writers' creations, but also helps to shed light on the spiritual aspirations and ideological orientations of literati such as Tai Jingnong during the turbulent times.
