北魏宣武、孝明二帝統治時期，雖然與南朝始終處於戰爭狀態，但是北魏内部對於南朝入北士族的態度，卻較孝文帝時期，發生了相當明顯的變化。這使得入北南朝士人得以更加深入地參與北魏的文化建設與文學活動，爲北魏後期乃至東魏北齊時期北方士人熱切學習南朝文學的風氣打下基礎。但是歸根到底，造成這種態度轉變的原因，並不在於南朝文化處於絶對優勢，而是北魏政權正統性的確立，政治文化局面的變化，以及北魏上層因此進行的自主選擇。本文選取入北瑯琊王氏成員群體作爲個案，通過研究其居處與葬地、婚姻仕宦、參與文化活動的情況以及墓誌文本，對琅琊王氏融入北魏社會的過程進行探討，從而進一步分析這一群體入北後對於北方文化進程的影響，以及從中體現出的，北魏上層對待入北南人，乃至南朝文化的態度變化。

This article focuses on the Langya Wang Clan members’ migration from the Liang dynasty to the Northern Wei dynasty and discusses the Clan’s integration into the Northern Wei society by examining multifarious aspects of their life, including residences, burial places, marriages into imperial and noble families, political careers, literary activities, and epitaphs. During the rules of Emperor Xuanwu and Emperor Xiaoming in the Northern Wei dynasty, the Langya Wang Clan’s cultural influence led to a distinct change of the court’s attitude toward the immigrants from the southern dynasties. This article argues that the reasons for this change of attitude lie not in the dominating southern culture but in the northern regime’s need to establish and maintain its legitimacy, its changing political and cultural conditions, and the Northern Wei nobilities’ own initiatives.
