本計畫擬以名分觀念看吐蕃由部落聯盟制演進至王朝體制，吐蕃如何建構與宣示王室統治權的正當性，如何安排社會高低位階，如何建立社會秩序等。自從引進外來宗教佛教以後，王室如何試圖以新宗教的意識型態，改變君臣分際，並試圖以新立僧相，改變官場生態，進而試圖改變傳統名分秩序，因而導致王朝崩解。至宋代時期，漢史料所載之吐蕃，其名分秩序的重建，是否一仍唐代吐蕃的舊軌，抑或另起爐灶？凡此皆為本計畫關切的重點。本計畫取材以唐代吐蕃時期所遺留的文獻為主，諸如敦煌古藏文卷子、吐蕃碑銘等，並輔以唐宋時期的漢文史料對吐蕃的記載等，希冀對上述所提出的諸多問題，透過前述名分觀念分析所蒐得之史料，得到解答，並以之為例，檢視唐宋接續期間，吐蕃名分觀念是否為繼承式的演進，抑或改頭換面？
