Recently, Xiang Wenbo's statement that "China has become a construction machinery garbage dump" has aroused public attention, and even second-hand machinery has also been called for ban. Although the domestic manufacturing industry has been clamoring for the introduction of second-hand products in the past two years. In addition to Xiang Wenbo, Liugong Chairman Wang Xiaohua, Zoomlion’s Chairman of the Board of Supervisors Long Guojian, and others have expressed opposition. He Qinghua, Chairman of Sunward Intelligent, even cited imported second mobile phones as "the quality of which is uneven, harmful to the environment, and unfavorable to the domestic industry. Five major crimes such as promotion.

　　Despite this, the domestic buyer's market for second-hand construction machines is still considerable. Take excavators as an example. In 2011, the total sales of domestic market machines were about 170,000 units, of which imported second mobile phones accounted for 14.25%.

　　According to users of second-hand machinery, imported second-hand construction machinery is cost-effective. Not only is it more durable than some domestic mobile phones, but also foreign brands have a strong ability to maintain value. The machine he bought two years ago is more than 100,000 yuan, and now the price is still more than 100,000 yuan. , Now the family cars are all joint ventures, all second-hand. Some of the old second-hand phones are more fuel-efficient than domestic first-hand phones, and the quality is stable. Second-hand prices are very favorable, which can create more profit value.

　　Hou Yuhui believes that the domestic construction machinery industry has only developed for more than 20 years. If the import of second mobile phones is not restricted, the gap between domestic and foreign industries will become larger and larger. The country should introduce policies to encourage and support domestic products, and foreign countries are in technology, management, manufacturing, and technology. All are more advanced than us. Domestically, they are all equipped with high quality. Although they use foreign engines and hydraulics, they have poor reliability. Why restrict the second mobile phone? Does not support domestic products, will never develop.
