Guide: China or a developing country is not the reason why China should not develop the world's fastest high-speed rail, because surpassing the old technology and directly adopting the latest technology are the biggest late developing advantages of developing countries. The so-called "white paper" has no burden, Good at writing the latest and most beautiful words, good at drawing the latest and most beautiful pictures

being a developing country is not the reason why China should not develop the world's fastest high-speed rail, because surpassing the old technology and directly adopting the latest technology is the biggest late developing advantage of developing countries. The so-called "a piece of white paper, no burden, easy to write the latest and most beautiful words and draw the latest and most beautiful pictures"

the world railway industry is facing an unprecedented development opportunity in decades. It is gratifying that China occupies a pioneer position in this industry; However, it is worrying that China's high-speed rail, which has leapt to the world's most advanced level in just a few years, could have been called a successful example of China's strategic emerging industry. However, our promising high-speed rail industry, and even the entire Chinese railway, fell into a huge whirlpool of public opinion in 2011, and suffered a biased and unfair public opinion siege in China. Some of the siege methods have reached the point of barbarism. After former Minister of Railways liuzhijun was sacked due to economic problems, liabilities, ticket prices, safety (although the Wuhan Guangzhou high-speed railway with a maximum speed of 394 kilometers per hour has been running for nearly two years without any safety accidents)... All imaginable topics were tortured. The high-speed railway seemed to be the target of thousands of people at one time, and the development of high-speed railway was said by some people to be a reckless wrong decision, or even a crime, The July 23 Wenzhou bullet train accident (officially named as "July 23 Ningbo Wenzhou Railway Traffic Accident of special significance") has added fuel to the fire. Under the enormous pressure of public opinion, the entire Chinese railway industry has experienced perhaps the most violent shock since the founding of new China: two comprehensive and substantial speed reductions within a year, the Beijing Shanghai high-speed railway operation speed has been reduced from the maximum speed of 380 kilometers per hour at the beginning of the design to 300 kilometers, and the railway construction has come to a complete standstill... All these have seriously damaged the reputation of China's high-speed railway and the entire Chinese railway, It also greatly weakens the comparative advantage of high-speed rail over other transportation modes such as aviation. It was not until the conclusion of the July 23 accident investigation team of the State Council was released that it began to slowly return to normal

indeed, criticism is a right, but criticism without any professional knowledge can not be the basis for decision-making, let alone deliberate and malicious fabrication. If we let the cheap so-called "sense of justice" overwhelm science and reason, and let ignorance and rumors dominate decision-making, it would be a tragedy for a country and a nation. Therefore, it is valuable to analyze some of the most widespread criticisms against the high-speed railway and the entire Chinese railway industry and clarify the facts

the first issue that needs to be argued is related to the overall decision-making - is China's high-speed rail really ahead of schedule? The answer is: no! China's high-speed railway and China's railway are not only not ahead of schedule, but also backward in development

we need to understand that China is still a developing country, which is not the reason why China should not develop the world's fastest high-speed rail, because surpassing the old technology and directly adopting the latest technology is the biggest late developing advantage of developing countries. The so-called "a piece of white paper, no burden, easy to write the latest and most beautiful words and draw the latest and most beautiful pictures". Before the popularization of copper wires, we used the large bending modulus of elasticity as the test to show that optical cables were used on a large scale. India and Africa did not popularize fixed lines, but first developed mobile communications on a large scale. The bottleneck restricting developing countries from giving full play to this late developing advantage lies in the gap of funds and talents. Since we have broken through these two gaps, why don't we fully explore this late developing advantage and be self restrained

history has proved that any late developing country, whether it is Britain, the United States, Germany or Japan, must have such aspirations and implement them into such practical actions. The founders of new China have already clearly realized this. On december13,1964, Chairman Mao Zedong added this paragraph when revising the draft government work report of Premier Zhou Enlai at the first session of the third National People's Congress, Later, it was quoted by the people on December 31: "we cannot follow the old path of Technological Development in the world and follow others step by step. We must break the Convention and try to adopt advanced technology to meet the needs of customers! Technology will build China into a socialist modern power in a short historical period." The ambition of catching up is not equal to blind arrogance. Chairman Mao Zedong is also revising the government work report of the first session of the third National People's Congress. He has changed some words a lot, such as "the level of scientific research has been greatly improved" to "somewhat improved"; "We already have a group of world-class scientists and engineers", cross out the word "world"; "Some research achievements have reached or are close to the world advanced level" is replaced by "some research achievements can already be regarded as advanced level"; In order to build China into a powerful country with four modernizations in a short historical period, the term "short" is changed to "not too long"; "Only in this way can we rapidly develop our own economy" is replaced by "only in this way can we relatively rapidly develop our own economy". We should not only aspire to catch up with China, but also be vigilant and restrain our inertia after we successfully catch up, so as not to be overtaken by countries lagging behind China following the same path

some public opinion criticized the high-speed railway construction for being ahead of schedule on the basis of the low attendance rate of high-speed railway on a specific line at a specific time. In fact, in this sense, the high-speed railway should be "ahead of schedule", and it is a crime not to be "ahead of schedule". If there is continuous and serious full capacity and overload immediately after the opening, it indicates that the design transportation capacity is seriously underestimated, which is a serious decision-making error, and the loss is hundreds of times greater than corruption, because it not only delays the opportunity of social and economic development, but also expands the newly built line, and the cost is much higher than that of completely new construction

by examining the growth of China's GDP and various transportation modes, we can see more clearly that the development of China's railways has lagged behind the objective needs of national economic development for many years; The leapfrog development of high-speed rail construction in recent years is not only a leap forward, but also a remedy for the debt. From 1990 to 2010, China's GDP rose from 1866.8 billion yuan to 40120.2 billion yuan, an increase of 20.49 times. During this period, the growth of railway operating mileage, passenger turnover, cargo turnover and other indicators with a fixed angle gasket is far less than that of GDP. Compared with the other three transportation modes, such as road, civil aviation and water transportation, the growth rate of almost every indicator is the smallest:

on operating mileage, The railway increased from 58000 km to 91000 km, an increase of 57%; Roads increased from 1028000 km to 4008000 km, an increase of 290%; Civil aviation routes increased from 507000 kilometers to 27 kilometers. The handling method is very simple, 65000 kilometers, an increase of 445%

in terms of passenger turnover, the railway increased from 261.3 billion person kilometers to 876.2 billion person kilometers, an increase of 235%; Roads increased from 262billion person kilometers to 1502.1 billion person kilometers, an increase of 473%

in terms of freight volume, the railway increased from 1506.81 million tons to 3642.71 million tons, an increase of 142%; Roads increased from 72404 million tons to 2448052 million tons, an increase of 238%

in terms of freight turnover, the railway increased from 1062.2 billion ton kilometers to 2764.4 billion ton kilometers, an increase of 160%; Roads rose from 335.8 billion ton kilometers to 4339 billion ton kilometers, an increase of 1192%, or nearly 12 times

according to the above data, we can see that in the past 20 years, the passenger turnover per unit operating mileage has increased by 113% for railways and 47% for highways; The freight volume per unit operating mileage increased by 54% for railways and decreased by 13% for highways; It shows that the railway transportation efficiency improves faster whether it is freight or passenger transport. During this period, the freight turnover per unit operating mileage increased by 66% by railway and 231% by road, indicating that too many goods were transported by road that was not suitable for long-distance freight transport, which would damage rather than improve the efficiency of the entire transportation system. Just look at how much Shanxi coal has been trucked out over the years, and you can see this. Even if we do not consider the road congestion that has been greatly aggravated by this, consuming a large amount of gasoline and diesel oil in exchange for coal is not a reasonable way of energy exchange in any case
