Through the static analysis, we think that traditional power is a protogenetic power; Tibetan Buddhism is a peculiar religion form that Indian Buddhism blended into the indigenous culture of Tibetan, it has doctrine, sandhana, ceremony and so on, and forms the religion power of worshipping living Buddha as base. The state power forms in the patriarchal clan system society, but it is thought political coercive power, even violence in the XunHua Tibetan area.

通过静态的分析，我们认为传统部落权力依靠循化藏区内对传统部落制度的文化价值认同的惯性得以维持和延续，是一种原生的权力形态；藏传佛教是印度佛教融入到藏族本土文化之中形成的一种独特的宗教形态，具有教义、修行到仪轨等一整套神秘主义的色彩和强化宗教认同的神圣化的意识形态，由此形成了以活佛崇拜为基础的宗教权力；王朝国家权力形成于以汉族为主体的宗法社会之中，它的强制力的一面依靠传统的宗法制度而被塑造成具有神权色彩的政治权威，然而在循化藏区由于文化认同的关系，王朝国家的政治权威被还原为政治强制力乃至于暴力。
