Restricted exports for large TBMs? Biden was unexpected, foreign **.
China's technological development seems to have begun to surpass that of the United States and the West. Prior to this, the United States and the West had proposed the so-called"The jewel in the crown of industry", a variety of advanced technologies are listed.
But people did not expect that these advanced technologies have now been gradually surpassed by us, and it can be said that the technological monopoly of the United States and the West has been broken in many fields, and in many areas we are overtaking in corners.
For example, Huawei, a well-known national technology company, has achieved overtaking in the field of 5G technology, changing the situation that American and Western communication companies have long dominated a large number of basic technologies. Huawei's 5G can now be said to be the world's leading existence, both in terms of the number of basic patents and the number of equipment shipped"Ahead of the curve"。
In fact, in addition to the rapid development in important areas such as chips and communication technology, we are also developing rapidly in some less attractive areas. For example, the C919 large aircraft and the Red Alliance system, which were hotly discussed by many domestic netizens some time ago, are examples of our extraordinary achievements in the field of civil aviation manufacturing and operation systems.
Our developments in the field of heavy equipment and compact equipment are even more astonishing. For example, our technology in armored machinery has risen from a blank slate more than a decade ago to a world leader.
Our country has always had"Infrastructure Maniacs"This not only refers to the rapid development of China's infrastructure industry, but also refers to China's exquisite technical level in the field of infrastructure equipment. However, more than 10 years ago, the armored machinery used in China's infrastructure projects was basically purchased from abroad.
According to public information, in 1997, we spent 700 million yuan to buy two used armored vehicles from Germany, and since then we have purchased another 130 armored vehicles. It was these TBMs that underpinned our excellent infrastructure technology at the time, but we also realised that it was not feasible to import them alone, and we had to replace them with locally produced EPBs.
Since 2002, we have set up an armoured machine R&D team, and we have achieved a number of technological innovations while disassembling German armoured machines. With the efforts of many R&D personnel, we manufactured the first unit in China in 2005"China Railway No. 1"Armoured machine.
If, at this point, we are moving away from dependence on American and Western EPBs, then our next step is to gradually complete the localization replacement and start entering the international market.
At present, about 90% of China's domestic shield machines are produced in China, and foreign shield machines have basically withdrawn from the Chinese market. In addition, China's armored machinery has also begun to be shipped to the international market on a large scale, and now accounts for 65% of the global market share.
It is worth paying attention to the fact that now it is our turn"Stuck neck"Judging from the public information, we have limited shipments of large shield machines in the European and American markets, which also makes it difficult for the United States and Western countries. After all, with the support of China's manufacturing production and shipment, the overall cost and shipment of lithography machines are relatively low.
Therefore, foreign manufacturers are actually more inclined to buy the shields that we send. Now that we're starting to limit shipments of some large lithography machines, it's hard to run out of large shields in the U.S. and Western countries, even though their production capacity is far from keeping up with demand, and it's much higher.
It can be said that if it were not for the excellent performance of Chinese armored machinery, it would be difficult for American and Western manufacturers to accept ** and low production capacity. But now, American and Western manufacturers may be starting to tangle.
In fact, with the development of science and technology in China, we have made technological progress in more and more fields. Even the so-called American and Western"The jewel in the crown of industry"It has basically been taken away by us, and only the field of semiconductor chips has not been completely surpassed. But from the perspective of China's core development, it is only a matter of time.
All along, it was the United States and the West that squeezed other people's necks, and now it is the turn of the United States and the West to be squeezed by us.
