1. Economic prosperity and strong military strength.
Shang Yang's political reform made Qin an advanced and prosperous country at that time. Because the new law encourages farming, Qin's economy has developed rapidly, the production level has improved significantly, and there has been a situation of "giving enough to others". Fan Wenlan said in "A Brief History of China": "In the ten years of the new law of Qin State, Qin people rejoiced, the roads were not picked up, the mountains were not thieves, the family gave enough to others, the people dared to fight in public, and the villages and towns were governed, so Qin State became the biggest power." At the same time, due to the praise of the meritorious military service, Qin Jun's combat effectiveness has been greatly enhanced. Unified measurement provides a standard measurement standard for the whole country and promotes commodity exchange. Although the implementation of the county system, the title system and the equal system suppressed the people, it brought some stability to the people and was conducive to the development of production and the prosperity of Qiang Bing.
2. Talents from all over the world gather in Qin.
Due to Shang Yang's political reform, Qin was strong and economically prosperous, and talents from all over the world gathered in Qin. There was a climax of absorbing and using foreign talents in the Qin Dynasty, and most senior officials were filled by foreign talents. Ruhe is 13, of which 12 is non-Qin. Qin also formed a system of absorbing and using foreign talents, that is, the guest official system, which initiated the management of honest officials. Xun Kuang, a famous thinker, described it as "a hundred officials are in awe, disrespectful, frugal and respectful, loyal and disloyal", and the court "listens to everything, spares no effort, and is as happy as there is no cure".
3. Military victory, territorial expansion and national strength enhancement.
Shang Yang's political reform made Qin's foreign war a great victory, expanded its territory and further strengthened its national strength, thus reversing its long-term backwardness and passivity. In 355 BC, Qin Xiaogong and Wei Huiwang joined forces in Du Ping, ending Qin's long-term "no alliance with China vassal states" and improving Qin's position among the vassal states.
In a word, Shang Yang's political reform was an important milestone in the history of Qin State, which made a new Qin State "changing customs, enriching the people and rejuvenating the country, and enjoying happiness for the people" appear in the land of western China, and had a far-reaching impact on the future development of China's history.
