What fields does Mitsubishi Heavy Industries Group involve?

Mitsubishi Heavy Industries is the largest military production enterprise in Japan. In 2003, the amount of military orders received from the Defense Agency was 280 billion yen, ranking first among all military enterprises. Equipment produced by Mitsubishi Heavy Industries, such as F-2 and F- 15J fighters and Type 90 tanks, has played a central role in both the Air Self-Defense Force and the Ground Self-Defense Force. In the Maritime Self-Defense Force, Mitsubishi Heavy Industries has built almost half of submarines and one third of destroyers. Its position in the Japanese military industry can be seen.

Historical evolution and summary

The predecessor of Mitsubishi Heavy Industries can be traced back to the Meiji Restoration. 1884, Iwasaki Yataro, the founder of Mitsubishi, leased Nagasaki Shipyard from the Ministry of Industry and Information Technology and named it Nagasaki Shipyard. Later, it developed into Mitsubishi Shipbuilding Co., Ltd., and in 1934, the company was renamed Mitsubishi Heavy Industries Co., Ltd. because its business expanded to heavy machinery, airplanes, railway vehicles and other fields.

After World War II, Mitsubishi Heavy Industries was divided into three companies: West Japan Heavy Industries Co., Ltd., China Japan Heavy Industries Co., Ltd. and East Japan Heavy Industries Co., Ltd. in 1950. However, with the changes of American policy and Japanese domestic politics, in 1964, the three companies merged to rebuild Mitsubishi Heavy Industries Company. During this period, the automobile department of Mitsubishi Heavy Industries became "Mitsubishi Automobile Industry Co., Ltd." on 1970.

At present, Mitsubishi Heavy Industries covers machinery, shipbuilding, aerospace, atomic energy, electric power, transportation and other fields. By April 2004 1, the registered capital was 265.6 billion yen and the number of employees was 34,306. It has 9 overseas offices or representative offices, 9 branches, 6 research institutes and 9 institutions. The annual order amount is 2 1 59.2 billion yen (from April1day, 2003 to March1day, 2004), and the annual sales amount is 654.38+094065438+0 billion yen (the statistical date is the same as above). Among them, from the perspective of the proportion of departmental sales to total sales, ships? 6? 1 Ocean plate accounts for 8%, nuclear energy plate accounts for 23%, mechanical steel structure plate accounts for 20%, aviation? 6? 1 Cosmic plate accounts for 17%, industrial plates such as vehicles and machine tools account for 29%, and other industries account for 3%.

Mitsubishi Heavy Industries is a member of Mitsubishi chaebol. Today's Japanese chaebol appear in the form of so-called Jing Lian (the pronunciation of Japanese character "Tong"). Mitsubishi series companies are all members of the "Jinyaohui" (which means Friday meeting) organized by Mitsubishi Group, including (for the sake of unification, this paper adopts its Japanese Chinese character name or English original name):

Asahi Glass (Glass, Chemical Company), Kirin Beer, Nippon Oil, Tokyo Marine Nikkei Fire Insurance, Tokyo Mitsubishi Bank, Nikon Camera, Japan Post, P.S Mitsubishi (engaged in construction industry), Mitsubishi Aluminum, Mitsubishi Chemical, Mitsubishi Chemical Machine, Mitsubishi Gas Chemical, Mitsubishi Land Institute (engaged in real estate industry), Mitsubishi Automobile and Mitsubishi Land Institute. Mitsubishi Trust Bank, Mitsubishi Shentong, Mitsubishi Iron and Steel, Mitsubishi Paper, Mitsubishi Warehouse, Mitsubishi Research Institute ("Mitsubishi Research Institute" in Japanese), mitsubishi electric, Mitsubishi Electric Wire Industry, Mitsubishi Fusangka Bus, Mitsubishi Materials, Mitsubishi Rayon and Meiji An Tian Life Insurance.

Companies in the same series can work closely together, and each company can provide good products or lower prices for other brother companies within its own division of responsibilities. For example, the Japanese mail ship is a big order of the shipping department of Mitsubishi Heavy Industries, while mitsubishi electric provides mechanical and electrical products for Mitsubishi Heavy Industries. Mitsubishi Iron and Steel, Mitsubishi Shentong, Mitsubishi Aluminum, Mitsubishi Integrated Materials and other companies can provide reliable raw materials for Mitsubishi's shipping and aerospace departments. Companies such as Mitsubishi Bank and Tokyo Maritime can provide loans and special insurance services (such as space launch insurance). Nikon's optical products and Mitsubishi resin's new materials are all indispensable parts of high-tech weapons.

Mitsubishi Group also has some subsidiaries and social groups as its periphery, including:

"IP Talk" Group (engaged in calling card business), Hot Ocean Hedong (Iwasaki Gongtai Memorial Hall), MT Insurance Service Co., Ltd., Kanto Pavilion (a hotel transformed from the former residence of Iwasaki family), Koiwai Agriculture and Animal Husbandry, Xiangnan Suburb Club, Jingjiatang Library Art Museum, Yitong Group (mainly the property management company of Mitsubishi Bank of Tokyo), Dainippon Paint, Dia Advanced Social Research Consortium, Diamond Family Club (a matchmaking agency jointly funded by 29 enterprises of Hsi Chin Club), mainly serving the internal group), Chitose Seiko, Oriental Library, Yorozu (a company engaged in real estate agency and advertising agency), Mitsubishi Gold Club (a friendly organization of the chairman and general manager of 29 Mitsubishi companies), Mitsubishi Club, Mitsubishi Economic Research Institute, Mitsubishi Broadcasting Committee, Mitsubishi Consortium, Mitsubishi CC Research Institute (an IT research institution), etc.

It can be seen that through the cooperation and division of labor of large groups, Mitsubishi Heavy Industries can obtain various supports such as capital, technology, raw materials, upstream products, financial services and sales from brother enterprises and groups. This is very beneficial to the development of enterprises.

The following is the introduction of Mitsubishi Heavy Industries' military-related departments:

A boat? 6? 1 Marine Business Headquarters

Shipbuilding industry is the earliest department of Mitsubishi Heavy Industries. At present, the division has four shipyards, including Nagasaki, Kobe and Shimonoseki, to build military products.

Nagasaki Shipyard: The battleship Musashi was built in Nagasaki Shipyard during World War II, and it is also the main destroyer manufacturer of the Self-Defense Force. Many types of ships have been built, such as Taidao Wind Class, Flag Wind Class, Hazelnut Name Class, Chaowu Class, King Kong Class and Gaolang Class.
