Shipyards are actually a lucrative industry.

Of course, this is mainly due to the current rise of ocean trade and the gold boom in exploring the Golden Continent.

The shipyard is very profitable, and the reason why the total profit is not as much as that of the Ryukyu sugar industry is mainly because the shipyard is constantly expanding, and several new factories have been opened one after another, each of which is larger than the other.

There is also the fact that the employees of the shipyard are really high-paid, from apprentices to masters, the salaries are quite high, and Liu Jin pays attention to the training and inheritance of technology and skills, and establishes the corresponding shipbuilding school.

As we all know, schools are basically bought and sold at a loss, with large investment and small returns, which is why ships are expensive.

The investment is very large, and if the special R&D expenses are quickly included, the investment will be even greater.

Let's talk about another super profitable glass.

Now all kinds of glass products are not only popular in Daming, but also exported to the Waguo, Ryukyu, Nanyang and other regions, glass manufacturing technology has always been firmly in the glass factory under the command of Liu Jin.

Glass is not worth much, but it has made Liu Jin a thing that only rich people can consume, and the profits are really amazing.

The profits of glass factories have always been very high, and they have continued to skyrocket with the hot sales of glass.

In the thirteenth year of Hongji, the total profit of the glass factory exceeded 30 million taels of silver, and the reason why it was not as good as the Ryukyu Sugar Industry was mainly because the growth was not as fast as that of the Ryukyu Sugar Industry, but the total profit was the first among all industries, and it could be said that it was a proper hen that laid golden eggs.

However, the glass factory is gradually falling into weakness, everyone is not stupid, and now they gradually understand that glass is actually a very ordinary thing, so they are not willing to spend too high a price to consume, so that in the Ming Dynasty, the price of glass products has to fall again and again, which makes its receivables and profits are facing a huge test.

This is also the reason why Liu Jin continues to explore overseas markets.

After deceiving Daming's own people, and then deceiving fools outside Daming, anyway, the world is very big, let's cheat for a round first, as for not making much money in the future, let's talk about it then.

These are very profitable deals mentioned above.

In addition, there are industries such as Miyun Iron Factory, Cement Factory, Textile Factory, Machinery Factory, Changlu Salt Factory, etc., although the receivables and profits are far inferior to those mentioned above, they earn tens of millions of taels of silver at every turn.

However, in these industries, receivables and profits are actually quite considerable, and the key is that the development is full of stamina.

As far as Miyun Iron Works is concerned, now Miyun Iron Works has successively built more than 10 blast furnaces, employing more than 100,000 employees, and the steel output produced has almost reached the point of monopolizing the entire Daming iron and steel output.

Iron is a thing that is closely related to people's production and life, and the price is not cheap, and the Miyun Iron Works is more about not selling pig iron and steel, but processing steel into various products and then selling.

Processed into all kinds of agricultural tools and steel bars for construction, these are not high-profit products, and the real money is still munitions and weapons.

Miyun Iron Factory, it is not only an iron factory, now it is the largest arms dealer in the Ming Dynasty, the production of arms and weapons is very much, whether it is the traditional sword armor, or the new musket, artillery, Miyun Iron Factory has production, and the quality is good, the price is low, now the weapons and equipment of the Ming army are all purchased from the Miyun Iron Factory.

Everyone knows that arms and weapons are the most lucrative business.

However, because the main customer is only the Ming military, the price will not be too high, so the profit is low, and there is no overseas arms market, this profit is very difficult to rise.

The development speed of Miyun Iron Works is also very fast.

Steel has been in great demand since ancient times, and it will never be enough unless it can reach the kind of steel production of 100 million tons in later generations.

Therefore, the Miyun Iron Works also began to build the Songhu Iron Works in Songhu, and the iron ore of the Songhu Iron Works mainly came from two places, one was the Ma'anshan Iron Mine in later generations, and the other was the famous Daye Iron Mine in Hubei in later generations.

The quality of iron ore in these two places is very good, it is a very small number of high-quality iron ore in Daming, and the key is that it can be transported to Songhu here by relying on the waterway of the Yangtze River.

The future development direction of Miyun Iron Works is mainly these three directions, conventional steel smelting, arms and weapons manufacturing and machinery manufacturing, these three fields are very promising.

More importantly, steel is an important indicator of a country's strength, and high-quality weapons need steel to build.

The profit margin of cement plants is very low, and the competition is also very fierce, and the large and small cement factories in the Beijing and Tianjin areas do not know how many, which can be described as a red sea of competition.

But fortunately, the cement has just come out, and its role is very large, building bridges and paving roads, building houses and walls are indispensable, so its demand is also very strong.

Although there are many cement plants, the demand for cement in the whole Ming Dynasty is also very strong, so that the supply of cement has always been in short supply. 202 eBooks

In addition, the imperial court implemented the grassland town plan on the grassland side, and built towns everywhere on the grassland, and the demand for cement was very large.

In addition, the south began to develop, and the demand for cement was also very strong, and many cement factories in the north came to the south to set up factories and continue to open branches

Therefore, the entire cement industry in Daming is still quite good.

As the ancestor and leading brother of the cement industry, Tianjin Cement Plant has also developed extremely rapidly, not only the leader of the cement industry in Beijing and Tianjin, but also the first in output and sales.

It is also rapidly opening new factories in Nanjing, Songhu, Guangzhou, Ryukyu, Quanzhou, Wuhan, Nanchang and other places in the south, continuously improving its output, seizing market share, and always firmly maintaining the leading position in the cement industry.

However, cement is a thing, because there is no large machinery in this era, so it requires a lot of manpower, and Liu Jin's positioning of cement from the beginning is for the construction of the Ming Dynasty, so its price is very cheap.

Compared with other industries, the profits of the Tianjin cement plant are much lower, and the total profit of Hongzhi in the past 13 years is only a few million taels of silver.

Let's talk about the Changlu Salt Field.

With the rise of the Changlu Salt Farm, this year is to completely defeat the Hui merchants and occupy the entire Ming salt market, whether it is in the north or the south, almost everywhere is using the salt of the Changlu Salt Field.

Even in order to seize the market, Changlu Salt Works not only built salt farms in Bohai Bay in the north, but also built salt farms here in the southern Ryukyus and Guangxi salt farms.

The salt farms in the Ryukyus were exclusively for the provinces south of the Yangtze River, and the salt farms in Guangxi were exclusively for the southwestern provinces, completely driving the salt merchants among the Hui merchants out of the salt market.

Relying on the salt drying method, the salt produced is not only high in yield, but also very high in quality, and the price is also cheap, and there is still a large amount of surplus for the entire Ming Dynasty.

So much so that Liu Jin also had to find more ways out to pickle salted fish, well, the ocean fishing has increased greatly, the fish can't be eaten, and the salted fish is also increasing, and the salt is exported to the Wa Kingdom, Ryukyu, and Nanyang.

Liu Jin didn't plan to make money on this thing, so the price of salt was much lower than before, only a dozen yuan a catty, but the profit was still very considerable.

In the thirteenth year of Hongzhi, the Changlu Salt Farm still contributed more than 10 million taels of silver to the major owners behind it.

There is no way, the output is too large, and after the price is low, market consumption is also stimulated, or monopolistic trading.

Many salt farms opened by the imperial court have no business, and after Liu Jin gave a message to Emperor Hongzhi, he also directly closed these salt farms and changed all the household registrations of the stove households to agricultural registration, which made countless stove households can't help but cheer.

Finally, I don't have to boil salt for generations, and I finally don't have to endure the oppression of those salt factory officials.

Like the military households after the military system reform, they cheered and chanted long live, as if they had been reborn.

This is also an important reason why the Ming Dynasty is becoming stronger and stronger, military households, stove households are related to the fate of millions, and they have gradually been liberated in the thirteenth year of Hongzhi.

Because of the times, many stove households have no skills themselves, and they do not have any land products or the like.

After they couldn't boil salt, they also poured into factories to work and go fishing at sea, and a large number of people responded to the call of Ryukyu and Nanyang and chose to immigrate to Ryukyu and Nanyang.

This also greatly promoted the germination of capitalism in the Ming Dynasty and the development of overseas colonial industries.

The previous industries are all profitable, and the only loss-making industry under Liu Jin is the machinery factory.

Liu Jin raised a lot of craftsmen in the machinery factory, and also opened a lot of schools to carry out systematic and professional training.

In a short period of time, these are loss-making transactions, and they all need to be constantly invested in money.

It is not so easy to raise craftsmen, and now the craftsmen are very high, and the treatment in all aspects can not be bad, and the construction and training of schools can not be completed overnight.

In addition, the machinery factory also shoulders a lot of research and development tasks, such as the steam engine and electromagnetic research that Liu Jin explained here, which want to continue to invest money and throw money into it.

Therefore, the machinery factory is now losing money, and it is not a small loss, it will lose almost one million taels of silver to Liu Jin a year, and its only income now is the sale of textile machines and looms and bearings for four-wheeled carriages.

However, these things are developing very rapidly, and the profits are still considerable, and it is expected that by next year, the machinery factory will basically be able to maintain profit and loss.

Of course, it doesn't matter to Liu Jin whether he makes money or not, the main thing is to rely on this machinery factory to get some important scientific and technological things out of the future, which is the most important thing.
