It is impossible to deny many things! This is also a weakness!

China is fortunate to be a big shipbuilding country, but at best it is only a "shell-building" country.

It is an obvious fact that the shipbuilding industry in China is falling into the "hull industry". A large number of core components are produced either by importing or purchasing patents, and the average profit of the shipbuilding industry has dropped to 3-5%.

In fact, it is the same to build a plane, a car and a ship. The engine has the highest scientific and technological content and the highest value.

Diesel engine main engine is the most valuable auxiliary equipment in civil ships, and the price of main engine generally accounts for about 10% of the total ship price.

Because the core technology of marine diesel engine is mastered by two giants, Wasilan and Man, Man and Wasilan always occupy the top two in the marine main engine market.

According to the statistics of China Shipbuilding Industry Association (600 150), the loading rate of marine equipment produced locally in China is less than 50%, including a considerable number of products of foreign joint ventures or wholly-owned enterprises.

In contrast, Japan, a shipbuilding power, has a localization rate of over 95%, and South Korea has a localization rate of over 85%.
