拓跋始祖神元帝力微後裔是北魏王朝統治的根基,也是中古內徙胡人貴族化運動的先導。宗室的貴族特權性突出表現在仕進起家問題上,朝廷參照晉制為其安排凌駕庶姓勛貴的起家等級和威望顯赫的職位,使之在仕途競爭中捷足先登。宗室選的成型對構建北方貴族閥閱序列具有重要意義,同時也是北魏優禮宗室政策的濃縮及皇權主義伸張的客觀需要,卻也加快了王朝衰亡的步伐。

The royal clan group was the foundation of the Northern Wei Dynasty and the precursors of the aristocratic movement. Their nobility was strikingly reflected by their official positions. The court arranged the posts of prominent prestige and the ranks of royal clansmen according to the system of the Jin Dynasty which enabled them to outstrip others in post competition. This system played an important role in the formation of aristocratic order and imperial regime. It was the reflection of the unique imperial policy and the need for expanding the imperial power of the Northern Wei Dynasty,but at the same time,it also speeded up the decline of the dynasty.
