Hello, this is at the beginning of the reform and opening up. There was a period of thought of "it is better to buy than to build, and it is better to rent than to buy". At that time, it was mainly concentrated in the field of heavy industry.

1. From a historical perspective, this is just a trend of thought, and it does not mean it is the mainstream.

From a current perspective, the United States uses technological blockade to fight trade wars. This can be seen from the sentence " The view that it is better to build than to buy, and to rent than to buy, is obviously out of date. This sentence originated from the trend of thought in the early days of reform and opening up, and it did not represent the mainstream even at the beginning.

In the 1920s and 1970s, China launched a "Four-Three Plan", which meant the introduction of a number of complete sets of equipment from abroad, all of which were "turnkey", which meant that they would all be built for you. Well, the key is given to you, and you are not involved in the manufacturing process.

When Wuhan Iron and Steel Co., Ltd. introduced the 170nm rolling mill, in order to save foreign exchange, they were not even willing to buy the drawings, so that they were unable to imitate them later. In 1977, the first phase of Baosteel was planned to be built. It continued the previous method and was completely built by the Japanese. It was eventually called a project that included the introduction of toilets in the first phase.

Later, in 1982 when we were planning to build the second phase of Baosteel, we proposed the principle of “joint design, cooperative manufacturing”. This was actually a common model in the early stages of reform and opening up. Trump Responsible for China Forced external transfer of technology actually means this.

In other words, the manufacturing at that time was not just about renting but not building, but was limited by conditions, and even the confidentiality of some external technologies was not allowed. This trend of thought was not allowed at that time. It is not the mainstream. Learning to imitate and have your own technology is the most authentic trend of thought.

2. Is the logic of this sentence correct? It cannot be generalized

Whether the logic of "it is better to buy than to build, and to rent than to buy" is correct, actually depends on who it is targeted at, what kind of product it is, and what era it is in.

If you are an individual or a company, this is basically true, because all commodities have an industrial chain. Individuals or companies have one part of their own industrial chain and cannot control them all. For example, we eat The meals, clothes, and useful mobile phones and computers are all bought. If you make them yourself, you may spend a lifetime before they can be formed.

If it is a country, it also depends on the specific product. If it is something that can definitely be bought, such as clothing department stores, this is actually correct. The United States has always been buying products made in China. If it is not definitely If you can buy it, it depends on whether others are willing to sell it. I guess the United States will definitely promote manufacturing. However, if it is technology such as chips, then this sentence is definitely wrong. After all, Trump in the United States knows how to use technology to get stuck. In fact, he just understands the loopholes in this sentence.

In short, in different eras, for the same people and things, the choices of buying, renting, etc. will actually be different. Just imagine that 30 years ago, it was impossible for ordinary families to buy a car. It was not as good as buying. Rent. Nowadays, most families have cars. There are many brands and affordable prices. It is better to rent than to buy directly.

We have to understand this sentence from the scene, and everything will be fine.
