China's high-speed rail is a symbol of Chinese design, Chinese manufacturing, and Chinese innovation, and its importance is self-evident. It is precisely because of its importance that many media and individuals use this hype and borrow questions. Some media have exaggerated reports on high-speed rail, which makes readers have a wrong view of high-speed rail; some media have degraded behavior, deliberately discrediting high-speed rail technology to attract the attention of everyone. For China's high-speed rail, it is not advisable to raise it up or to lose it. Only by correctly understanding its advantages and problems can we have a faster pace of progress.
 
　　1. Does China's high-speed rail technology lead the world?
 
This is of course true. Although many unscrupulous media propaganda speculations that China's high-speed rail technology mostly comes from abroad, lack of core technology, etc., this arrogance is not credible. China's high-speed rail did introduce some foreign technology in the early days, but this is not a simple imitation, but the introduction of technology, digestion, absorption, and innovation.
 
At present, China is fully capable of relying on its own technical strength to build a "system-wide" high-speed rail. In the area of high-speed rail equipment and infrastructure construction, it is the world's first echelon.
 
—— China's high-speed trains have achieved independent research and development of the full-spectrum system. Key technologies such as bogies, train network control, and vehicle body manufacturing have been independently controlled, and are at the same level as foreign giants such as Siemens and Alstom. To the world's advanced high-speed rail technology, from the previous "looking up" to the current "leveling."
 
——The key technologies, core software and complete sets of train control equipment of the train operation control system are all localized, and the foreign products can be fully replaced. The high-speed rail transit control system solutions can be provided according to different working conditions such as high cold and sand. China's complex natural climatic conditions ensure stable and safe operation of high-speed rail.
 
—— China's high-speed rail bridges, tunnels and other infrastructure infrastructure capacity are among the highest in the world. China's railway infrastructure construction equipment is highly autonomous and can cope with various complicated and dangerous geological conditions. It is affectionately called "foundational demon" by netizens.
 
Second, the key small parts, large machine tools still rely on foreign guns and cannons?
 
Are key small parts and large machine tools still relying on foreign guns? This problem actually exists. At present, the high-speed rail has a high degree of autonomy and advanced technology, but the shortcomings in basic equipment manufacturing and technology research and development still exist, especially in the manufacture of parts.
 
According to the "Economic Information Daily" report, in some advanced train production workshops, many machine tools and equipment labels indicate that the "place of birth" is a western country. Many engineers told reporters that there is no large-scale precision machine tool product in China, but it has not been used before. The quality of the product is designed to be safe and not rushed to change. It has to rely on the "foreign gun".
 
In addition to high-end machine tools, some components such as bearings, wheels, gear transmission systems, bogies, and some core components of high-speed trains are still required to be imported. In addition, the electrical parts of the high-speed rail car, similar to the pantograph, converter, brakes, etc., are mainly imported or assembled with the core components of the foreign party in the joint venture company. The reliability of the domestically produced products is also There is a gap.
 
Of course, not all parts depend on imports, and many domestic companies can also produce, but the cost is too high, the output is too low, and can only be replaced by imports.
 
3. Does the high-speed rail need to be highly localized?
 
Some people think that since China's high-speed rail has reached the world's leading level, it is necessary to make a big effort to create "small parts" and achieve high localization? The answer is necessary.
 
On the one hand, it is not necessary to only affect the research and development enthusiasm of researchers. If the research itself loses interest in researching how to break through the constraints of “small parts”, then breakthroughs and innovations will only be more difficult.
 
On the other hand, in order to make their own technology lead, Western countries often ban exports on core technologies and key equipment. The ZTE incident is a foregone conclusion. Therefore, even though economic globalization has improved the production efficiency of high-speed rail, maintaining high localization will enable China's high-speed rail to have lasting competitiveness.
 
Forty years of reform and opening up, China's science and technology have developed rapidly and with each passing day, and high-speed rail technology is constantly improving and moving forward. From the poor and the white to the leading world, from nothing to independent innovation, the road of China's high-speed rail is the direction that China's manufacturing, Chinese design, and China's innovation must advance. The wheel of reform is rolling forward, and China on the high-speed rail is rushing.
