The distribution characteristics of local administrative institutions in the Qin Dynasty are: the central government set up complicated departments, the central government implemented "three public officials and nine ministers", and the local government implemented the county system.

This distribution strengthened the dominance of the Qin dynasty and enabled the central government to effectively supervise the localities. It strengthened the centralization of the Qin dynasty and stabilized the regime and stability of the Qin dynasty.

The Qin dynasty (22 BC1to 207 BC) was a unified empire developed by the state of Qin at the end of the warring States period. Qin Wangzheng, the founding monarch of the Qin Dynasty, claimed to be the first emperor, hence the word emperor. The country name is Qin, and the royal family name is Qin. Therefore, it is not called winning Qin in history books, and it is different from other countries as a state power of Qin. It was only 15 years from the unification of the six countries to the demise of the Qin Dynasty.
