The centralization of power in Qin dynasty officially confirmed the beginning of feudal monarchy, and the transformation from slave society to feudal society was a historical progress. Its national strength was significantly enhanced, and it possessed all the characteristics of feudal society, which laid the foundation for the later feudal system.

However, it also has its disadvantages. After GongSunYang's political reform, it was more than one hundred years before Qin took power. Although this system has brought great benefits to the state of Qin, it has shown a rigid beginning. For example, in the Bobby Chen incident, they were delayed by the rainstorm, so they could be pardoned or mitigated. However, the law does not give flexibility, and it only deals with "deliberate delay", which undoubtedly increases the difficulty of law enforcement and the strong dissatisfaction of the people.

Moreover, centralization was too unified, and the emperor combined all kinds of powers, which of course avoided the danger of splitting and independence, but it was also possible to act arbitrarily, but it was of historical progress significance in the society at that time.

Positive role and influence:

National strength is enhanced;

Conducive to the development of feudal economy and culture;

It is conducive to the initial establishment of the territory of the motherland and the consolidation of national unity.

It is conducive to the formation of the Chinese nation with China as the main body.

It laid the basic pattern of China's feudal political system for more than 2,000 years, which was used by feudal dynasties and strengthened and improved.

Negative effects: It strengthened the autocratic authority of the emperor, intensified contradictions, and the Qin Dynasty died short-lived.
