唐王朝经营东北的目的能否实现,即东北诸族是否内附唐,取决于唐与突厥双方力量的消长变化。突厥降户叛乱引起东北政局的变化,又给突厥的发展壮大造成了机会,最终导致了后突厥的崛起,并且一度主导了东北诸族;后突厥的复兴是促使幽州成为军事重镇、平卢节度使建立的直接或间接因素。因此,隋至唐前期,是由隋唐王朝与漠北游牧政权争夺东北地区统治权的时代,虽然最终以突厥的失败而告终,但唐与突厥均是东北地区的主导力量,东北诸族是否内附唐是一个决定性的外在因素。 Whether the purpose of operating the northeast in the Tang Dynasty can be fulfilled, that is, whether or not the northeastern tribes belong to the Tang Dynasty depends on the growth and decline of the power of both the Tang and Turks. Turks to bring about the rebellion led to changes in the political situation in Northeast China, but also to the development and expansion of Turkic created opportunities, eventually led to the rise of the latter Turks, and once dominated the Northeast; after the revival of Turkic is to promote Youzhou become a military town, Ping Lu Jiedushi makes the establishment of direct or indirect factors. Therefore, from the Sui to Tang dynasties, it was the era when the Sui and Tang dynasties scrambled for domination over the northeast by the nomadic regimes of Northern and Southern Sui and Tang dynasties. Although they finally ended in the failure of the Turks, both Tang and Turks were the dominant forces in Northeast China. Tang attached is a decisive external factor.
