Ship electronics is the general term for hull electronic control devices and shipboard electronic control equipment. Ship electronic products are an important part of the ship's accessory products, and they are components with relatively high technical content and added value in the ship.

From the perspective of development trends, ship electronic technology is developing in the direction of digitization, automation, integration, intelligence and integration. With the gradual improvement of users' requirements for high cost performance and high reliability, the manufacturing of marine electronic products has gradually developed in the direction of serialization, modularization and standardization.

The upstream industries of the ship electronics industry are mainly electronic component manufacturing and parts processing, electronic information manufacturing, software and integrated circuit industries, and the downstream industries are mainly shipbuilding, shipping, government departments that supervise ships, and the navy.

According to statistics, the value of ship's electronic products accounts for about 15% of the value of the entire ship. Although the overall market size of ship electronic products is not very large, the impact on the shipbuilding industry is not small. Especially for the Chinese shipbuilding industry, the backwardness of the ship electronic industry is still a major bottleneck restricting the development of the shipbuilding industry.

The ** market of marine electronic products is mainly controlled by European and American countries. At present, the production of marine electronic products is mainly concentrated in developed countries such as Germany, Britain, Denmark, Norway, the United States, Canada, Japan and South Korea. Although China has greatly improved the level of R&D and manufacturing of marine ancillary equipment such as diesel engines, generator sets, and propellers, marine electronic products such as marine navigation equipment, communication equipment, steering systems, and control systems mostly use foreign products.

Due to the lack of mastery of core technology, lack of professional talents, insufficient investment in research and development, difficulty in breaking through technical barriers, and low level of industrial chain coordination, China's shipbuilding electronics industry is still at the low end of the industrial chain. Although China has entered the ranks of international shipbuilding powers, the domestic shipbuilding industry is very weak. Domestic shipbuilding companies generally import ship electronic equipment from developed countries, resulting in high procurement costs. Some key high-tech, high-value-added marine equipment and components cannot be produced in China and can only rely on imports. This is in sharp contrast to the rapid development of China's shipbuilding industry.

Domestic ship electronic equipment lacks core technology, no brand, no international marketing and after-sales service network, single product, low technical level, backward technology, poor reliability and other outstanding problems, and it is basically still in the learning and follow-up stage. Domestic ship electronics companies mainly act as agents of foreign products, and few independently researched and developed products. The only products that can be independently developed in China are magnetic compass, gyro compass, log, depth sounder, etc., and they can only be used on some domestic ships. Domestic ship electronics companies generally can only provide a single sporadic product, and there is a big gap compared with similar foreign products in terms of product technical performance, quality, variety and specifications.
