I will no longer explain the comparable cases because the topic is related to China's economy and I don't want to distort it here. However, see that, unlike other countries, China has recorded consistent trade surpluses since 1995, beginning to intensify strongly in the 2000s, when it was still a low-income economy, when it still had and still has a long way to go be able to be self-sustainable. When other countries were in the same socio-economic situation as China, they did not seek to please the export lobby, they looked for ways to increase domestic demand and, therefore, increase the standard of living, encouraged by external capital and then starting to be self-sufficient. in internal investments, after the economy entered the middle income and reached high income, they began to orient themselves towards the export market. All these comparative study cases are problematic for a model for China, as China has a population many times larger than any of these compared countries and this is the problem: the population of China has not taken advantage of these surpluses, because this is advantageous for exporters and groups associated with it, society does not benefit from it.
When the Chinese sell more products to foreigners than they buy from them -- that is, when exports are greater than imports --, the country is said to have a trade balance surplus. When Brazilians buy more than they sell -- that is, when they import more -- there is a deficit in the trade balance. For some obscure reason, the press and academics recurrently warn about the "dangers" of having a deficit in the trade balance, implying that an economy is only healthy when it has a trade surplus -- that is, when it sends more products to foreigners than that you acquire from them. Continuously, practically every year the government announces a new "industrial policy" to stimulate the export sector and repress imports. What almost no one says is that, for the inhabitants of a country, the only benefit brought by exports is precisely imports; The only function of exporting is that, with that, you can import.
When China sells its products abroad, the foreign buyer pays the Chinese exporter in dollars, which is the international currency of exchange. When a farmer in the interior of Brazil sells soybeans to a company in Shanghai, the Chinese pays the Brazilian exporter in dollars. He deposits dollars into the Brazilian's account. But since, by government decree, the only currency in China is the renminbi, this Brazilian will then have to exchange these dollars for renminbi in Brazil. And who will buy Brazilian dollars? Almost always, banks, through their brokers. And what will banks do with these dollars? They will sell to importers, who will use them to, obviously, buy products from abroad. What matters, therefore, is that, in the end, these dollars that were sold by Brazilians will be used to import foreign products. Without these dollars it would be impossible to import. For Brazilians who are not in the export sector, this is the only function of exports: they allow imports to occur. It's exporting that matters.
However, things start to get murkier when we see economists totally obsessed with exports and fanatically opposed to imports. What would be the point of exporting without importing? From the Brazilian citizen's point of view, the country's exports of soybeans, oranges and steel are only good for them because they bring in dollars that allow them to import iPads, notebooks, books, cars and several other things. Other than that, exports are not at all advantageous. On the contrary: the more a country exports, the smaller the supply of these exported goods will be on the national market. The greater the export of soybeans, oranges, coffee and steel, the smaller the supply of these products will be for Brazilians, which means that their prices on the domestic market will be higher than they could be if they were not exported. In general, whenever the trade balance presents a record surplus, this means that the Brazilian citizen was deprived of a greater supply of goods, both those produced nationally and which were exported, and those produced abroad and which could not be imported by government restrictions.
There are some explanations. Firstly, as the export sector has a very well organized lobby, and as the government needs dollars to compose its international reserves and to intervene in the exchange market, it is not necessary to be a great political scientist to imagine that both (government and exporters) will work in deep symbiosis. Each needs the other's help. On the other hand, importers are diffuse and do not have an organized lobby (to tell the truth, I don't even know if there is an importer lobby). Additionally, imports mean outflow of dollars. And the outflow of dollars means the government losing the ability to implement exchange rate policy to help the export sector. Again: you don't need an academic degree to realize that importing goes against the interests of both the government and the export sector.
If a country -- for example, China -- adopted a non-inflationary monetary policy, its exchange rate would continually appreciate. This stable currency environment, with growing exchange rate appreciation, is extremely attractive for foreign investments. Imagine, for example, that US$100 is invested in China when the exchange rate is 1.50 renminbi. Upon arriving in China, 100 dollars turns into 150 renminbi. At a profit rate of, let's say, 10%, 150 renminbi turns into 165 renminbi. As during this period the renminbi continually appreciated against the dollar -- because of the non-inflationary monetary policy --, suppose that, when it comes time to repatriate profits, the dollar is costing 1.30 renminbi. Therefore, 165 renminbi turned into US$127. Therefore, 100 dollars became 127 dollars, which gives a real profit rate of 27%, much higher than the initial 10%.
In other words, the investor benefits twice. This continuous exchange rate appreciation, together with the guarantee of respect for private property and contracts, would make the country exceptionally attractive to international investors and ensure the flow of foreign investments, which would consequently guarantee the necessary imports for the country. In the case of China, this applies in the period 1993-2014, where the exchange rate operated in a semi-fixed regime, with the flow of FDI heading to China and, at the same time, China oriented towards exports, which ended up leaving the country's consumers without a back seat in economic policy.
The country would have foreign currency without the need to accumulate reserves. The country would not need to accumulate large international reserves because investors would have nothing to fear. A large volume of international reserves is only necessary for countries that operate with an exchange rate anchor or countries that do not have macroeconomic stability. Even in the event of an outflow of dollars, the country's non-inflationary policy, combined with the exchange rate policy, would guarantee prompt exchange rate stabilization. Inevitably, foreign investments would return.
In other words, a country can perfectly obtain the foreign currency it needs without needing to have large export industries. In this scenario, such industries could perfectly turn to national demand. And if there is no demand for your products, whether in the national market or abroad, then it is because no one wants them. And it would make no sense to insist on this, subsidizing such industries.
The bureaucrats who manage the Chinese government have determined that it is good for China to sell valuable goods they produce to foreigners, thus reducing the supply of these goods to the Chinese themselves and, therefore, depriving their population of a higher standard of living. . Obviously, this is a bad deal for most Chinese citizens, but a great deal for the sheltered export tycoons. It is also a great deal for American citizens who buy good and cheap Chinese products. The Chinese government is subsidizing Americans' lifestyles. Meanwhile, Chinese citizens, who would be happy to be able to consume the goods produced by Chinese industry, end up being deprived of these same goods, as the preference is for them to be exported to foreigners. This is the basics of mercantilism. Everything good that a country produces must be sent abroad with government subsidies, leaving its population with a smaller amount of goods that they could consume. The export sector wins and government bureaucrats win. Such an arrangement does not bother the bureaucrats who run the PBOC in the slightest. It's not their money. They receive salaries to create electronic renminbis at the request of the Chinese government and set this entire cycle described above in motion. There is no reason to reverse this.
Mercantilists have always been convinced that having a Central Bank subsidizing the export sector is extremely beneficial for a nation, and that the reduced quantity of goods and services that will be available to domestic consumers (both as a result of more domestic products being exported and due to lower imports due to the more devalued currency) is something of no importance. As long as this subsidy coercively extracted from a majority to a minority is not seen as a program to transfer wealth from the poorest (ordinary consumers) to the richest (barons in the export sector), the entire arrangement will maintain itself.
