Guide: China has gradually become a major construction machinery manufacturing country in the world, but it is still not a powerful country. The main reason is that compared with developed countries such as Europe, the United States and Japan, China still has a serious shortage in the manufacturing of key mechanical parts. Not long ago, Yang Baode, Deputy Secretary General of China Construction Machinery Association, made an investment in

China has gradually become a vegetable stall in the community, and the roadside vendors are also big manufacturers of plastic bags in the world, but it is still not a strong country. The main reason is that compared with developed countries such as Europe, the United States and Japan, China still has a serious shortage in the manufacturing of key mechanical parts. Not long ago, Yang Baode, Deputy Secretary General of China Construction Machinery Association, pointed out at an investment strategy report meeting that whether China can change from a big country of construction machinery to a powerful country depends on whether the manufacturing of engine, gearbox, high pressure, hydraulic pump and motor, as well as high-strength steel and other mechanical parts can be "bigger and stronger" in the next five to ten years

the sales of construction machinery are closely related to the national fixed asset investment, accounting for about 1.5% to 2.5% of the national fixed asset investment. Yang Baode believes that the change in the share of national fixed asset investment in the 12th Five Year Plan will directly affect the development prospects of the entire construction machinery industry. It is expected that China's construction machinery industry will maintain a sustained and steady growth in the next 20 years, which is based on many advantages such as China's future urbanization, transportation construction and the cost performance of products, which bode well for the construction machinery industry. One is urban construction. At present, China's urbanization rate is only 47.3%, which is expected to reach 65% by 2020, with an annual growth rate of 1%. Urban construction is a long-term project, which is undoubtedly a long-term benefit to the construction machinery industry. The second is traffic construction. During the 12th Five Year Plan period, the state invested funds in transportation and measured it with the improved optical fiber dynamic fatigue stretching method, which is expected to reach 10 trillion yuan, including high-speed rail, urban rail, subway and expressway. There is still a huge demand for construction machinery. Third, China's export construction machinery products are cheaper and more cost-effective than Europe, America and Japan. For example, a 22 ton excavator with similar performance costs 1.1 million yuan in the United States, about 900000 yuan in Japan, and only 700000 yuan in China. At present, China's construction machinery products have high acceptance in Africa, America and Europe

according to the data, the sales volume of construction machinery products in China has increased rapidly from 2001 to 2010. Among them, the total sales volume of excavators increased from 12397 in 2001 to 160000 in 2010; The sales volume of loaders increased from 26000 in 2001 to 220000 in 2010; In 2010, the national sales volume of bulldozers exceeded 10000 for the first time; Truck cranes have increased steadily, with an increase of 38000 in 10 years, and the sales volume has almost doubled 10 times; The number of road rollers also increased to 27000 in 2010. In this decade, the export share of China's construction machinery has shown a rapid growth trend. In 2001, the total import volume of China's construction machinery products reached 1.55 billion US dollars and the total export volume was 689 million US dollars. By 2005, the total import and export of China's construction machinery products had reached US $3.064 billion and US $2.94 billion respectively, which had been basically flat. In 2006, the export volume of China's construction machinery exceeded the import volume for the first time, realizing a trade surplus. By 2008, China's export volume reached 13.422 billion US dollars, the import volume was 6billion US dollars, and the trade surplus reached 7billion US dollars. During the "Eleventh Five Year Plan" period, the export of China's construction machinery products exceeded the import, and the trade surplus was basically favorable. At present, China's export targets are mainly Asia, Africa and Latin America. In 2009, the sales volume of construction machinery products exported to Asia, Africa and Latin America accounted for 75% of the total exports of that year, while Europe and North America accounted for 15% and 9.1% respectively. The high cost performance characteristics of China's construction machinery products gradually enable it to compete with manufacturers in developed countries in the market share of Europe and North America. During the "Eleventh Five Year Plan" period, some data of China's construction machinery industry has jumped to the first place in the world. For example, the sales volume of loaders in China accounts for 60% of the total sales volume of loaders in the world, and the sales volume of starters, tower cranes and other machinery is also much higher than that of other countries

the manufacturing level of construction machinery is one aspect of the national scientific and technological level, and the manufacturing of construction machinery parts is naturally also a very important link. Yang Baode's words are not unreasonable. He said that whether China can change from a big country of construction machinery to a powerful country depends on whether there is a significant interaction between the measurement of anemia and diabetes and the design and manufacturing level of high-strength steel and other parts in engines, gearboxes, high-pressure, hydraulic pumps and motors within five to ten years after the implementation of the 12th Five Year Plan, which is also regarded as a key design improvement, so as to achieve "bigger and stronger". In order to achieve this goal, he believes that China should take measures mainly from three aspects. First, while continuing to introduce foreign technology and parts, relevant foreign enterprises should be encouraged to build factories in China. Secondly, domestic parts manufacturers are encouraged to carry out self transformation and improvement. Third, encourage the main engine manufacturers to build their own hydraulic components and system technology progress, especially the production and technology improvement of parts and components such as hydraulic pumps and engines, which are highlighted in China's 12th Five Year Plan
