Many people have written papers now. A thesis is an article in which we study a certain problem in depth. So, have you understood this paper? The following is the conclusion paper of "Introduction to Mechanical Engineering" carefully compiled by me for reference only. Let's have a look.

Mechanical engineering plays an important role in the development of national economy. It is the basic industry and pillar industry of the national economy and the key to the transformation of economic growth mode from extensive to intensive. At the same time, machinery manufacturing is also an important part of national economic entities in various countries.

The development of mechanical engineering is closely related to the prosperity of national economy.

The development of machinery industry has promoted the development of social productive forces and made the social economy take off.

If the machine is rich, the country will be rich, and if the machine is strong, the country will be strong.

Therefore, the machinery industry has an important relationship with the development of the national economy.

Keywords: basic industries, pillar industries, key points, important components

Mechanical engineering has an important relationship with the development of national economy, and undertakes the task of providing technical equipment and production tools for various departments and industries of national economy.

Therefore, the development level of machinery industry affects or even determines the technological progress and industrial development level of relevant industrial departments to a great extent.

The development of machinery industry plays an important role in the development of national economy and national rejuvenation.

Its importance includes the following aspects.

First, mechanical engineering is the basic industry of the national economy.

The basic industry is the starting point of the national economy, which determines the scale and direction of the development of the national economy and provides various indispensable intermediate products, services and means of production for the development of other industries.

Machinery industry belongs to the "means" industry in the basic industry, which provides various means of production for the national economy.

The position and role of any industry in the national economy depends on the importance of the products it produces in economic life.

The whole national economy can be regarded as a huge converter from resources to products and services, and the machinery industry is the source of this converter. Therefore, the machinery industry has a basic position and role in the economy.

"If a worker wants to do a good job, he must sharpen his tools first." The main products of the machinery industry are the production equipment necessary for various industries, including himself, and the production equipment is the means of production for various industries in the national economy. This shows that the machinery industry is the basic production.

The importance of industry to the national economy.

Advanced manufacturing technology is the most fundamental foundation of a country, democracy and prosperity, so developing advanced manufacturing technology is a national goal, national interest and social interest.

In order to improve industrial quality, it is impossible not to improve manufacturing technology.

At present, the competition of international economy depends more and more on the competition of technology, especially the contest of manufacturing technology.

The level of manufacturing industry directly reflects the productivity level of a country, which is directly related to the transformation of traditional industries, the cultivation of emerging industries and the progress of science and technology.

Therefore, only by keeping up with the production technology can our machinery industry stand on the world and the national economy develop by leaps and bounds.

Two, mechanical engineering is the pillar industry of the national economy.

The development of any industry in the national economy must rely on the support of machinery manufacturing, which accounts for more than 60% of the national economic productivity.

Americans believe that the source of social wealth is machinery manufacturing, accounting for 68%.

At present, the four pillar sciences of mechanical manufacturing science, information science, material science and biological science are interdependent, but the latter three sciences must rely on manufacturing science to form industries and create social wealth.

The development of manufacturing science must also depend on the development of information, materials and biological sciences.

Therefore, the machinery manufacturing industry is the best meeting point for any other high-tech to realize industrial value, such as rapid prototyping machine, virtual axis machine tool, intelligent structure and system, etc. Although it has gone far beyond the scope of pure machinery, modern machinery and equipment, which integrates machinery, electronics, control, computer, materials and other technologies, embodies the connotation of humanistic and personalized development. It is still inseparable from machinery, and its value cannot be reflected without machinery.

From the perspective of the United States, since World War II, the United States has attached great importance to the development of machinery manufacturing.

Since the 1950s, American universities have set up industrial engineering majors to train talents in mechanical manufacturing systems, focusing on world market competition in an attempt to occupy the international manufacturing market.

In the early 1950s, when the first numerical control machine tool was born at MIT, the leading policy adopted by the United States in the machinery manufacturing industry was to adopt numerical control and computer group control to realize the road of small and medium-sized batch production automation dominated by the machinery manufacturing industry, so as to improve production efficiency.

However, practice has proved that this strategy is a failure. In the international competition of machinery manufacturing, Germany and Japan are winners.

In 1970s, we turned to learn from the experience of Germany and Japan, and realized the flexibility and automation of small and medium-sized batch production through group technology.

From 65438 to 0979, the United States Congress passed a bill to allocate funds for the development of flexible manufacturing systems, and in the late 1980s, the standardization of highly flexible fully automatic coolies was completed and extended to small and medium-sized enterprises.

However, due to ignoring the variability of the market and the role of human factors, it failed to gain the upper hand in the competition with Germany and Japan, making the machinery manufacturing industry go from bad to worse. It was once thought that machinery manufacturing has become a "sunset industry".

Through the demonstration of 10 years, the transition from flexible manufacturing to agile manufacturing is realized conceptually, the macro international market demand is closely combined with the specific company production, and the human factor is fully exerted to form a rapid response to the market, and a new concept of agile manufacturing is put forward.

Americans' attention and development of machinery industry is highlighting the importance of machinery industry as a pillar industry.

Third, the machinery industry is the key to the transformation of the national economic mode from extensive to intensive.

Generally speaking, the transformation of economic growth mode has two meanings: first, economic growth has changed from extensive growth with high input and low output to benefit growth with low input and high output; The second is to change the growth model of "big and complete, small and complete" blindly repeated construction under the condition of traditional planned economy, and develop into scale economy and intensive economy model based on division of labor and cooperation.

Whether it is to improve input-output efficiency or develop economies of scale, an important prerequisite for achieving these goals is advanced and efficient equipment.

The symbol of a country's economic development level lies not in what it produces, but in how it produces (in this case, advanced equipment).

The fundamental factor that determines how a country produces is of course the advanced level of means and the level of technical content.

Therefore, to grasp the key to the transformation of economic growth mode, we must first revitalize the machinery industry, especially the basic machinery industry and basic parts industry that serve the machinery itself.

In the second half of the 20th century, the machinery industry was called "sunset industry" because of its waste of resources and environmental pollution. However, in the 20th century, due to the development of high technology, mechanical engineering developed rapidly.

The machinery industry has moved from the early era of heavy waste of resources to the green era of rapid cleaning.

China is in a critical period of industrial transformation, and it is of great significance to accelerate high-tech innovation and realize the transformation from labor-intensive to technology-intensive

Judging from the evolution stage of China's industrial structure, when the task of "complementarity" of China's industrial structure is basically completed, the task of "upgrading" begins to be highly valued, and the transformation of national economic growth mode and structural adjustment enter a critical moment. Under the situation of "buyer's market" in the national economy, under the circumstances that all industries are faced with increasing depreciation, large-scale technological transformation and upgrading, and heavy equipment updating tasks, the importance of machinery industry with equipment as its main product is more prominent.

To improve the national economic structure in an all-round way, we must first revitalize the machinery industry.

Four, the machinery industry is an important part of national economic entities in various countries.

Machinery manufacturing industry is an important part of national economic entity, the main symbol of national competitiveness, an important source of tax revenue, and can also provide a large number of employment opportunities.

Even in the era of knowledge economy, manufacturing and high technology are closely combined and will still play a fundamental role in national economic life.

This can be proved by relevant data.

68% of the wealth in the United States comes from manufacturing, and about 49% of Japan's total national economic output value is provided by manufacturing.

In advanced industrialized countries, about 1/4 of the population is engaged in manufacturing, and in the non-manufacturing sector, about half of the people's jobs are closely related to manufacturing.

Let's look at China again. From the data of 20 10, it can be found that the GDP of China in that year was 10. 1% for the primary industry, 46.8% for the secondary industry, 40. 1% for the industry and 43. 1% for the tertiary industry.

Machinery manufacturing in industrial enterprises above designated size includes general equipment manufacturing, special equipment manufacturing, transportation equipment manufacturing,

The total industrial output value of electrical machinery and equipment manufacturing, communication equipment, computer and other electronic equipment manufacturing accounts for about 30. 13% of all industries.

Therefore, in general, the proportion of machinery manufacturing industry in GDP is 12.08%.

Judging from the history of mechanical engineering in China, the process of industrialization in China has been seriously hindered by the shackles of feudal system in the past century.

On the eve of the founding of the People's Republic of China, China's machinery manufacturing industry was almost zero.

Over the past 50 years since liberation, China's machinery manufacturing industry has made great progress, and started to have its own independent machinery manufacturing industry with great technical difficulties, such as automobile industry, aerospace industry and so on.

Especially since the reform and opening up, China's machinery manufacturing industry has made full use of domestic and foreign capital and technology, carried out large-scale technological transformation, greatly improved manufacturing technology, product quality and level and economic benefits, and played an important role in promoting national economic development.

In addition, there is the status quo of mechanical engineering in China: at present, half of China's fiscal revenue comes from manufacturing industry, which is well-deserved as the "cornerstone of China Economic Building".

In 2000, the added value of China's manufacturing industry accounted for more than one-third of the gross national product, accounting for 77.6% of the total industrial output value, taxes paid accounted for more than one-third of the total national tax revenue, and exports of manufactured goods accounted for 89.8% of the total national foreign trade exports.

The added value of China's machinery manufacturing industry ranks fourth in the world after the United States, Japan and Germany.

Conclusion: The accumulation of machinery is the main determinant of national productivity growth, and the development level of machinery industry affects or even determines the technical progress and industrial development level of relevant departments to a great extent.

Economic development is inseparable from mechanical engineering, and the level of mechanical industry will also be improved because of economic development.

Therefore, machinery plays an extremely important role in the development of national economy.
