1. From the economic point of view, the Silk Road greatly promoted the circulation of goods and took the lead in realizing trade and economic exchanges between the East and the West. The caravan brought rare animals, plants, furs, herbs, spices and jewels. Goods such as silk, tea and porcelain were shipped from the west and then from China, which enriched the daily life of people of all countries. In addition, China's cast iron smelting, sinking and other technologies were introduced to the Western Regions, which promoted the improvement of the social production level in the Western Regions, while China's four great inventions, silk weaving technology and lacquerware technology also spread to all parts of the world through the Silk Road, greatly promoting the production progress and even social changes of countries along the route.

The Silk Road is also a bridge for cultural exchange. Confucianism, Buddhism, Zoroastrianism, Manichaeism, Nestorianism and other cultures came to China with the opening of the Silk Road and spread along it, which greatly promoted the mutual penetration and tolerance between different countries and civilizations in the East and the West. China's silk products enjoy a high reputation in Europe, which leads to a social fashion. Meanwhile, western culture and technology have also spread to China through the Silk Road, making China and world civilizations blend with each other and enhance understanding.

The Silk Road also played an important role in politics and diplomacy. It strengthened the political ties between the Central Plains Dynasty and the Western Regions. Western countries have sent envoys to appear before the Central Plains. At the same time, Persia, Rome and other empires also sent envoys to China, which promoted the diplomatic exchanges between China and the West.

Generally speaking, the Silk Road was an important channel for economic, cultural, political and diplomatic exchanges between the East and the West in ancient times. Its opening and development have greatly promoted the progress and development of countries along the route, and also promoted the integration and mutual learning of eastern and western civilizations. Although the commercial function of the Silk Road has gradually weakened with the arrival of the industrialization era and the development of maritime traffic, it still has important historical and cultural value as an important historical heritage of the exchange between eastern and western civilizations.
