First, benefit from the rapid development of the industry At present, there are more than 1400 production enterprises above designated size in the industry, of which more than 710 host companies, employees 338,500 people, the original value of fixed assets 66.8 billion yuan, a net value of 48.5 billion yuan, total assets reached 2210 Billion yuan, the average profit rate in 2009 was 7.51%.

China's construction machinery sales and sales both exceeded the United States, Japan, and Germany ranks first in the world. The self-sufficiency rate of China's construction machinery has increased from about 70% during the "Tenth Five-year Plan" period to more than 80% at present, and the leap from manufacturing to creation has been gradually realized. Including loaders, excavators, truck cranes, road rollers, forklifts, bulldozers, and concrete machinery, a large number of engineering machinery products have leapt to the top in the world, and China has become a truly world-renowned engineering machinery manufacturer. In addition, because of the needs of special engineering operations such as the construction of metro rails, high-speed railway construction, and wind power construction, shield tunneling machines, rotary drilling rigs, large-scale construction cranes, and large-scale concrete box girder transportation and hoisting equipment exceeded the normal development speed and became new growth. point.

The concentration of production has increased significantly. The sales revenue of companies with sales of more than 1 billion yuan has accounted for 85% of the total in the industry. In 2005, there were only 22 companies, accounting for 40% of the total sales of the industry.

Large-scale construction machinery group grew above the average level of the industry. In 2010, sales revenue increased by 52.39% year-on-year, profit increased by 86.98% year-on-year, and more than 10 billion yuan exceeded 10 companies (XCMG, Zoomlion, Sanyi, Liugong, Shantui , Longgong, Xiagong, Komatsu China, Doosan China, Hitachi Construction Machinery, Kobe Steel.

Second, benefit from the company's scientific and technological progress, independent innovation Third, benefit from the engineering machinery product structure to further optimize the technical level of China's construction machinery products by quality, control technology, energy saving, environmental protection, safety and operating efficiency, can be divided into high, Medium and low-end products of three grades. High-end products, the use of international advanced engine power configuration; key hydraulic and part of the transmission components imported parts, or excellent domestic support; information control components including electronic components, hydraulic components, sensor components, etc. are also selected international brands. The technological level of the product developed in this way is close to the international advanced level. In the mid-range products, the localization rate of such products generally reaches more than 85%. The main components of product development are domestic matching components and raw materials. The reliability of the whole machine is compared with the international advanced level, and the gap is relatively large. It is the main product on the domestic market. There are many production companies, and product homogeneity and imitation are more serious. The low-end products are mainly aimed at low-cost costs, low product technology configuration, high failure rate, high energy consumption, and emission indicators are all below the national I standard. There is a safety hazard disc granulator. Such products, including simple agricultural engineering machinery, have sold more than 400,000 domestic units. According to industrial policies, in the "12th Five-Year" adjustment structure, such products should belong to the list to be replaced or gradually eliminated.

Fourth, benefit from the obvious improvement of the quality of construction machinery products The quality of construction machinery products has been improved in the competition. Both appearance appearance and surface quality, technical configuration and product reliability have shortened the gap with the international advanced level. In particular, the reliability of products has been significantly improved, and the reliability indicators of medium and high-end products have now been increased by an average of more than 100 hours. According to the National Construction Machinery Quality Supervision Center's inspection report, the average time between failures of the grader reached 711 hours, the internal combustion fork lift truck reached 418.5 hours, and the hydraulic excavator with a weight of 10 tons or less reached 782 hours, which is higher than before. substantial improvement.
