"This question is simple and simple, but complex and complicated!"

"The key to everything is to first figure out why countries mix silver and copper internally, and only copper externally?"

In Kyushu, there are many smart people.

Even if the New Year's coins given by the Song people are mostly silver, not real silver, but spices, silk, cloth, wine and other physical objects, which is why the New Year's coin mission is followed by the caravan.

"Because silver and copper are not equal!"

The empress said naturally.

Copper is recognized, but silver is not, the gold and silver mines in the north have long been emptied, and the gold and silver mines in the south are at their peak.

Occupy the Dashu of Jingzhou, the whole Ming Dynasty of maritime trade, the former troops entered the north of Jiaozhi, the latter started the northeast of Jiaozhi, a large area of gold and silver was dug out of the mountains by the natives of Jiaozhi, the two countries do not need to do anything, every year from Jiaozhi can pull back 30,000 taels of gold and 40,000 taels of silver.

This is a single year, year after year, dozens or hundreds of years, the gold and silver reserves in the hands of the two countries are almost accounting for three or four percent of the amount of Kyushu.

Besides, people are not stupid, why use gold and silver when they can buy things back with copper?

"No one in this world is a fool, on the surface, silver and copper are not equivalent, the cost of obtaining silver and copper is different in various countries, and in fact, there is a set of economic theories inside, didn't my sister ask last time, in the face of the economy of the Song people, how can Wu Chao turn the table?"

"At that time, I said that I wanted to change the anchor of the currency, and the first step was to increase the country's gold and silver reserves!"

The empress nodded, "What's the matter, you seemed to give the answer that time, but you didn't say anything, why are you going to say it today?" ”

"Theory can be said first, after all, the problem of Qian Zhuang is in front of you, but it is too difficult to lift the table based on theory alone!"

The equation pulled the empress into the study, "First of all, we have to make one thing clear, that is, everything must be followed, the principle of large quantity and cheap, scarce and expensive!" ”

"Isn't it the truth that the grain is cheap and hurts the peasants?" The empress should be harmonious.

"That's right!"

Equation nodded.

"The principle is this principle, to put it mildly, anything including gold and silver, the specific value is fluctuating, the value of copper coins is approaching, the number of copper coins is enough, the circulation time is long enough, and the people recognize it!"

"Second, even if the copper coins minted by various dynasties and countries vary in size and size, and in copper content, the value of a copper coin is degraded, and how much is it degraded?"

"A small number of losses, you can not remember it at all!"

"But gold and silver are different, a little bit of color, the loss is more than a dozen catties, dozens of catties of rations, no matter how big the heart is, it hurts! Even if the color is not broken, is the cost of gold and silver dug up in the north really equal to that of gold and silver dug up in the south? ”

"In the face of such losses, I don't think even a generous person can be generous!"

Kyushu does not have the concept of exchange rate, but people have a rod scale in their hearts, and they want to do everything that makes money, and they don't want to do anything that loses money.

In a small area, the exchange ratio of gold, silver and copper can tend to be balanced, and after the range is enlarged, this kind of convergence does not exist.

"That's right!"

"Then here's the problem!" The equation spread his hands, "If the money village is open to the outside world, the biggest attraction should be to store interest!" ”

"Regardless of the level of interest, as long as we don't want to destroy the overall situation, no matter how low the interest is, we must give it!"

"Given this interest, sister, how many people do you think will save money?"

The empress thought for a while, "There won't be too much in the beginning, but it won't be too little, businessmen are more cautious in pursuing profits at the same time, bills of exchange are the big ones, and the people on the border need a little time to accept it, but there may be more in the future!" ”

The long border can't be managed at all, right?

Many people living on the border either have no household registration in one country, or the household registration of two countries is in their hands.

"No matter how much, the domestic storage will definitely rise!"

The empress nodded slightly, the border is not easy to tidy, there is seven cents of interest in the territory, and then there is a county wang, and the county old man promotes, and the savings will definitely rise.

"Stored together, as soon as the loan comes out, there will be more copper coins on the market, and if there are more copper coins, the existing value system will be affected, and if you don't care about anything, the value of a single copper plate will continue to fall, so you need more copper plates to buy the same thing!"

Equation stared at his sister's expression, and he was a little worried about whether his sister would be able to communicate with him.

"You go on!"

"In this case, the biggest loss is the people, left unchecked, there will be chaos, the rich and powerful will not watch the copper money flood and depreciate, because this is not only about copper money, but also about gold and silver, in order to keep copper money not depreciating, they will only pass all this on to the people!"

"However, we can now spend a lot of money through cash-for-work, so as to stabilize prices as a whole, even if there is still a small increase, but after cash-for-work and interest payments are paid, this part of the increase has also been wiped out!"

"Not only that, after the completion of the project, the wealth that will continue to be produced, the passage of a canal, and the transformation of a middle field into a field, this impact is not a moment, the second is a few years or even more than ten years, under the continuous output, the extra copper coins will be offset by various outputs, and the final price will naturally return to a more appropriate degree!"

The market is complex, and it is impossible to have a single line, but now we are talking about theory, and we will naturally give answers according to theory.

"I need to think about it!"

It's a bit chaotic, this one will go up and one will fall, on one side is wealth, on the other hand, copper coins, I vaguely feel that I have caught something, but the empress is not sure after all.

"Sister, think slowly, I'll get something to eat!"

Looking at her sister who was in deep thought, the equation handed over the study to the other party.

Entering and exiting the courtyard, a sweet smell of food came to my face, and I saw half a lamb hanging above the charcoal fire, and the three people next to the charcoal fire were already enjoying it.

"How fast?"

Looking at the roasted half-charred lamb, the equation is somewhat unfinished.

"The finished product in the Drunken Immortal Building is now just a sample, which is a habit after the end of the winter hunt!" Lao Puya didn't touch the barbecue well, and explained with a bowl of hot mutton soup in his hand.

"And this habit?"

Some of them eat well, no matter how good the mountains are, they are incomparably in the city, compared to this mouthful of meat, the equation wants to eat two mouthfuls of vegetarian.

"The habit of bullshit, in my opinion, is just idle and looking for trouble!" Li Yanting touched his mouth, "No accident, in three or four days, the city will be in chaos!" ”

A group of energetic young people have been holding back for 20 days in the mountains, and have been out of the mountains to recuperate for a few days.

"Why, I'm not going to get rich?"

It's good to vent, drinking is the best vent, when I first returned to the city, the equation was still wondering what so many shops were doing, I thought it was to receive, but I didn't expect it to be harvested!

"Rich? The old man advises you to close the door, so as not to be smashed in the end! Lao Pu smiled playfully.
