After system, in-depth research, from the perspective of application and the function in detail power products of classification. Can be seen from table 2, power supply products and can be divided into electronic power, chemical power and physical power three categories. Among them, electronic power mainly includes switching power supply, UPS power, air power, space power source and military power supply products; Chemical power YuanDianChi, batteries, including reservior battery and fuel cells; Physical power, including solar battery and temperature difference hair appliances.
Second, the power industry development history
According to the division of division experts of li, China power supply industry scale can be divided into three stages of development, according to the ministry of electronic industry statistics data and material, can delineate roughly development outline.
(1) the first stage as 1976, is China's power industry before the early stages of development.
Before liberation, China's power industry basic is blank, only the dry batteries, the small enterprise. The 1950s as building a large number of state-owned enterprises, as the electronic industrial raw materials, original devices and the machine industry development, power supply products also from scratch. 1959 have two factory and a school production five kinds of specifications 1600 many sets of power. To 1976, after 17 years of development, has been developed to 26 factory, 34 varieties, 52 specifications, 33,000 many sets of power. Production unit growth 8.7 times, variety specification growth 10.4 times and production growth 20.2 times. The first stage from scratch, although growth rate faster, the power industry scale still small.
(2) the second stage is the 1977 - in 1989, is China's power industry preliminary growing period.
This stage is the initial China's reform and opening, the economic construction, power supply industry also gradually accelerate gradually into rapid growth. 1989 power production enterprise has developed into 171 home, the product specification 340 kinds, annual output power 54 million sets. Production enterprise number than the 1976 growth 6.6 times, breed growth 10 times and production growth 1.64 times. In this one phase, with the rapid development of the power industry gradually, the power of scientific and technical workers need break original isolation and understand the external world. Since the mid-seventies onwards, power technology personnel spontaneous organizations technology exchange, 1978 convened the first national power technology exchange, 1983, established China power supply society, 1986 get approved by the state science and technology commission.
(3) the third stage since 1990, is China's power industry's big development period.
This stage, the ministry of electronic industry system unless the original outside, other industries and system, such as mechanical, posts and telecommunications, railways, electric power, military systems have power development and production, especially of township and village enterprises and private enterprises, the national springing from thousands of almost all over the country, the emergence of a batch of over 100 million yuan, or even exceed 10 million yuan of power supply enterprises. In these 10 years in, a large number of foreign products and company enters the domestic, and occupy a share, intensifies the market competition.
Third, the power industry development momentum
In the next few years, China's electronic information industry development will face a better system environment and development opportunity, provides the basis for related power the policy environment. With the speeding up of China digital informatization construction have been incorporated in the various economic entities, as China investment category city information and industry, enterprise informationization progress faster, China power market has a huge development space.
Beijing Olympics, Shanghai world expo and the Asian games in guangzhou for the ensuing economic growth and urban investment opportunities and power brought attention also worthy. With emergency linkage system, intelligent community construction as the key city informatization construction also gradually moving in the right direction in the future, it will be pulled in certain period of market growth important strength.
From industry applications look, 3G construction will drive the telecom and related consumption and sustained growth in IT services markets; Financial industry informatization construction to depth direction; continue E-government, digital city, the construction of the digital Olympics will be largely promote computer equipment, software and IT services market development; Agriculture, medical, construction and other traditional industry informatization will successively into deepening stage.
In finance, government, manufacture three fields, promoting the development of future power market related factors and hot trend is as follows:
1, financial

Electronic business speeding up development will bring financial industry, electronic finance construction of large-scale IT brought by IT grow mainly in room construction, ATM machine, self-help bank building, network construction, network desk set up and comprehensive investment, including power investment scale will also with overall IT investment and step by step.
(4) insurance market competition, operators to diversify away development
Along with the advancement of internationalization, Chinese insurance market main body also began with the international market, formed a wholly owned company, joint venture company, mutual insurance company and so on many kinds of business forms of main body. Insurance subject form of sound and emerging insurance company for the number of informatization construction of rapid increase bring greater demand. Different insurance company launch new products, need to build core business system and management system will correspond with the product. The main forms of IT investment to build room, installation ERP, CRM software, constructing the network platform, etc, thus to bring power to overall investment scale growth.
2, the government
(1) the "11th five-year" plan for future power investment will produce directive effect. Distribution
At present, the national and local government at all levels of the construction of e-government "11th five-year" plan are still in the process of establishing. To achieve the effective integration of the existing system, continue to improve the utilization level of information resource development, strengthen the construction of information security system will be "11th five-year plan" period of the construction of e-government main content. Above content on the power performance as construction of index are put forward higher requirement will constantly.
(2) the e-government assessment system consummation will become for government informationization external power
Along with the construction and application of e-government penetrated, e-government evaluation more and more get the government, enterprises and public attention. China's e-government evaluation system in order to gradually from portals to other government information program promotion, comprehensive and feasibility is gradually improve, increasingly the governments at all levels improve informatization construction level external power. Governments at all levels through comparing and evaluating each other, will help to learn from each other successful experiences, the timely discovery own problems, purposeful reforms. Both accelerated the pace of the construction of e-government, and make the electronic government affairs, the right track along the healthy move on.
(3) "about strengthen information resources development and utilization of opinions on work promoting government data center construction pace
CPC central committee general office and the general office of the state council issued on strengthening the information resources development and utilization of opinions on work. To improve the information resources development level, on the one hand, need to build perfect information collection system and database system, on the other hand, we should improve the relevant government departments, to realize the lateral and axial Internet information sharing. While the data center is to achieve these goals carrier. With various government information resources development and utilization, will surely promote the progress of the work related to the construction of data centers.
Three, manufacturing
China's manufacturing IT system construction has made good progress, enterprise informatization has small enterprises from the original pilot, demonstrations, and in some parts of the large and medium-sized enterprises based better in every industry, and gradually to different areas of enterprise promotion. But from the whole construction industry status, manufacturing informationization are still developing, different manufacturing sub industries in network construction, such as tobacco greater difference between management and operation of industry belongs to vertical industry planning and promote dynamics, its profession relatively perfect good communication private network construction, leading to the LAN and the tobacco enterprise portal s investment and construction level; And machinery and electronics, textiles, food and beverage industries is weak, the more regulation for independent operation status by itself, its network construction profitability and leading consciousness influence is stronger, the great difference construction level.
(1) the state tobacco monopoly administration issued outline of digital tobacco development, computer room construction has to go first
The state tobacco monopoly administration issued outline of digital tobacco development pointed out that building a digital tobacco, through to the implementation of integrated management of the entire supply chain industry, realize the market-oriented optimize the allocation of resources, in accordance with the "unified platform, unified database, unified network" overall technical requirements, the construction industry e-commerce, e-government and management decision the subject of three application system, forming GuoGuJu, covering framework with each provincial bureau of industrial companies, industry and commerce grass-roots enterprise the information construction situation.
(2) the national "11th five-year plan" period strongly support the automotive industry development, the group development strategy for the surf
"The 11th five-year plan automobile development planning" shows that automobile industry in our country in the "11th five-year plan" period will focus on three questions: independent research and development and improving enterprise of independent innovation ability,
