How to interpret the three ancient "commercial revolutions" from the perspective of time and space?

As we all know, we experienced various revolutionary activities in ancient China, including commercial revolution and political revolution, which is of great scientific significance to the later development. History is a discipline based on time, so the concept of time and space is of great significance to historical thinking activities and historical development. Therefore, based on the understanding of the concept of time and space of the three ancient commercial revolutions in China, the three commercial revolutions have different promoting effects on China's commercial activities.

First of all, the commercial revolution in Song Dynasty and Ming and Qing Dynasties promoted the development of market system and commercial towns respectively. During the Song Dynasty, due to the great tolerance for commerce, the economic system went market-oriented, the boundary between shops and cities was completely broken, commercial transactions were no longer regulated, and agriculture and handicrafts turned to the market, forming a long-term prosperous market. Secondly, the deepening of commercialization led to the emergence of various currencies in the Song Dynasty, and even the earliest paper money in the world was born. During the Ming and Qing Dynasties, due to the rapid development of urbanization, a large number of floating population flowed into cities, which led to the emergence of a large number of industrial and commercial towns and regional business groups, and the status of businessmen was greatly improved, which led to the germination of capitalism. Secondly, silver flows into the market and becomes money, which brings about changes in money.

Then, the third commercial revolution promoted the process of modernization. The third commercial revolution took place in modern times. At that time, due to the impact of western powers, the internal natural economy was greatly stimulated, and the domestic small-scale peasant economy disintegrated earlier with the invasion of foreign powers. Therefore, under the stimulation of foreign trade, modern commercial cities centered on trading ports have been formed, such as Guangzhou, Xiamen, Ningbo and other port cities. These emerging cities have acquired new technologies and management methods, got rid of the traditional urban model, formed the earliest private industry, promoted the development of national capital and the modernization process of China, strengthened the ties at home and abroad, and laid the foundation for the birth of the proletariat.

Finally, from the perspective of time and space, the three ancient commercial revolutions have played an important role in promoting commercial activities and urban functions.
