本文对易代之际历史与文学的研究价值与学术难点进行了梳理与归纳,指出其所以逐渐被学界所关注乃是由于这些历史转折关口政治的纷繁多变与士人的选择多元,由于文化价值的重估与思想观念的活跃,由于文学风格的多样与审美形态的趋新。而该领域研究的难点则在于文献的缺失与错讹、历史跨度过大所造成的认知模糊以及研究者所居立场的不易把握等等。而本文认为张晖的《帝国的流亡》一书在这些方面做出了有益的探索。 This paper sorts out and summarizes the research value and academic difficulties of history and literature in the days of the Yi Dynasty, pointing out that they are gradually being paid attention by the academic circles because of the ups and downs in the politics of these historical transitions and the multiple choice of scholars, The revaluation of values ​​and the activeness of ideas and concepts are due to the diversity of literary styles and the renewal of aesthetic forms. However, the difficulties in this field lie in the lack of literature and mistakes, the vague cognition caused by the spate of historical spans, and the difficulty of grasping the position of researchers. And this article thinks that Zhang Hui’s “The Exile of Empire” made a useful exploration in these aspects.
