In recent years, China has continuously strengthened its research on the R & D and utilization of graphene. The dependence of engineering machinery components on imports threatens industrial security. The dependence of engineering machinery components on imports threatens industrial security. Guide to information on China's engineering machinery: China is the largest country in the world in engineering machinery manufacturing. In 2010, China's sales revenue of engineering machinery reached 436.7 billion yuan, an increase of 38.3%. However, compared with the rapid development of host enterprises, the supporting industry of China's construction machinery industry is very weak, especially the key supporting parts need to be imported in large quantities, which not only restricts the production

China is the largest construction machinery manufacturing country in the world. In 2010, the sales revenue of construction machinery in China reached 436.7 billion yuan, an increase of 38.3%. However, compared with the rapid development of host enterprises, the supporting industry of China's construction machinery industry is very weak, especially the key supporting parts need to be imported in large quantities, which not only restricts the increase of product added value, but also seriously threatens the industrial safety

this is the information learned from the 2011 China (Changsha) International Construction Machinery Accessories Expo, which ended on the 25th. The first direction of the Expo held in Changsha, Hunan, which is trying to build "the capital of China's construction machinery": environmental protection plastics came into being. It is the first Expo held in China for the supporting parts of construction machinery. 273 Chinese and foreign enterprises participated in the Expo, and more than 3000 professional merchants attended the Expo

statistics show that in 2010, China has surpassed North America, Japan and Western Europe to become the world's largest construction machinery market. China's import of construction machinery reached US $8.399 billion, an increase of 63.2%; Exports reached US $10.341 billion, an increase of 34.2%, still maintaining a trade surplus

however, while a number of host manufacturing enterprises with international influence have sprung up in China, such as Sany Heavy Industry, Zoomlion, XCMG technology and Shanhe intelligent, the lagging status of China's construction machinery accessories has not been fundamentally changed, and the pattern of high dependence on imports of key accessories has not changed

longguojian, vice president of China Construction Machinery Industry Association, said that China is a big country in construction machinery manufacturing, but it is not a strong country. The main reason is that China is not strong in independent innovation, and is controlled by others in basic raw materials, core parts, key technologies, etc

jiaxiaowen, Secretary General of the construction machinery accessories Branch of China Construction Machinery Industry Association, pointed out that after the second phase of the project was put into operation to promote the logistics industry to be low emission, pollution-free and recyclable development, China is transforming from a large construction machinery manufacturing country to a powerful manufacturing country, and the country has raised the development of key basic parts industry to the top priority of China's construction machinery industry that needs to be improved. It is expected that after several years of efforts, we will gradually reverse the passive situation that the development of the basic parts industry is seriously lagging behind, break through a number of key manufacturing technologies for basic parts, develop a number of key basic parts, master a number of core technologies with independent intellectual property rights, and increase the supporting capacity of basic parts of major equipment to more than 70%
