唐代吐蕃軍事佔領區建制之研究

本文關注於唐代吐蕃時期，吐蕃在軍事佔領區所設的軍政機構，學界幾個尙待辯證的核心議題。如，軍政機構建制的原理及緣由，以及漢史料所載機構名與官職銜，它們是仿自李唐或本土自有的延伸？吐蕃的軍事機構設置在何處？各自統轄範圍為何？彼此間的階層統屬關係？與中央如何互動往來？兼論首席宰相可有兼任邊區軍政機構長官的可能性。筆者以漢藏文史料、碑文、簡牘與出土敦煌文獻考證出發，並實證地檢視、評論近現代國際藏學專家著作，綜合以上的研究材料，具體地針對前述核心議題，本文指出吐蕃軍政機構建制係將本部地方建制，移植於青海後，再擴張延伸於邊區，復因地制宜略有變化，實則呼應筆者所見，軍政機構建制之特色，即結合行政、軍事、生產三位一體，動員容易且編制簡單的原則。
