Why do people regard the improved steam engine as the most important technological invention in the first industrial revolution?

(20 19 New Curriculum Standard) Before the Industrial Revolution, mines in Britain were pumped by steam pumps. 1765, Watt, who repaired the water pump, invented a single-acting steam engine, which was finally improved into a "universal steam engine" with the cooperation and funding of the factory owner, and was widely used in the industrial field. This process shows that the main inventions in the production field during the first industrial revolution originated from labor practice.

(20 14 Yichang)1Since the middle of the 8th century, a series of technological inventions and innovations have appeared in the production fields of major capitalist countries, and large-scale machine production has gradually become the main mode of industrial production, and mankind has begun to enter the "age of steam" or industrialization era. This change is called the industrial revolution.

(20 15 Jingzhou)1In the middle and late 9th century, machinery and textiles, machinery and equipment, metal products, industrial raw materials and grains became the four main commodities in international trade. The main driving force of this phenomenon is the industrial revolution.

(20 15 Huangshi) many industrial sectors appeared in the industrial revolution, and the cotton textile industry first appeared.

Someone described the scene of Britain in the early19th century, saying that the spinning wheel used by women and girls all day from dawn to late at night has now been abandoned in the corner. Most hand looms that bang with the beat are idle. This shows that revolutionary changes have taken place in the field of production.

(20 18 New Curriculum Standard) According to the traditional view, Britain became the birthplace of the industrial revolution because it first had economic conditions such as technology and market. Later, some researchers believed that the main reason was that Britain established a constitutional monarchy; Some scholars have suggested that rich coal and iron resources, easy mining and other natural conditions are important factors. Accordingly, the understanding of the earliest industrial revolution in Britain tends to be comprehensive with the expansion of research perspective.
