Second, the analysis of the economic operation of the industry
1. The rapid development of the mechanical industry host provides a good opportunity for the industry.
In 2003, the machinery industry entered a period of rapid growth. The industrial added value of enterprises above designated size was 620 billion yuan, an increase of 26.05% over the previous year. The production, sales and exports increased in an all-round way, and the economic benefits were greatly improved, despite the substantial price increase and power consumption of raw materials. The impact of factors such as tight supply, the industry still has a rare good situation for many years. In addition to the food packaging industry, the sales of 13 major industries have reached a level of more than 25%. The industries with an increase of more than 35% are 54.91% of construction machinery, 42.30% of cultural office equipment, 38.69% of heavy mining machinery and automobiles. 36.75%. In addition to the cultural office equipment industry, the increase in profits has reached more than 25%. The increase of more than 50% is 127.67% of internal combustion engines, 79.71% of machine tools, 77.92% of construction machinery, 62.68% of agricultural machinery, 62.22% of instruments and meters, and general basic parts. 55.32% and cars 53.12%.
It can be seen that both sales revenue and profit growth have maintained a steady and strong momentum.
Among the statistics of 124 major products, there were 110 kinds of growth, accounting for 88.7% of the total number of products. Products with more outstanding growth are still some "hot spots" products. First, the automobile industry represented by cars leads the rapid development of the whole industry.
In 2003, the output of automobiles was 4.44 million, of which 2.02 million were cars. The production and sales rate was 98.39%. The contribution rate of the automobile industry to the growth of output value was 42.47%, ranking among the top in various industries. The second is power generation equipment. The demand for national key projects represented by power generation equipment is strong, which has led to rapid growth in the output of electrical and electronic products. The third is environmental protection machinery, guided by the national sustainable development policy,
The environmental protection industry has received unprecedented attention. The fourth is the machine tool with high technical content. In 2003, the output of CNC machine tools was 36,800 units, an increase of 47.73%, the high-precision machine tools increased by 42.51%, and the large-scale machine tools increased by 87.13%. 
The growth rate of sales revenue of various host industries related to the industry in 2003 is as follows:
Construction Machinery 54.91% Heavy Machinery 38.69% Automobile Industry 36.75%
Machine Tool 32.79% Basic Parts Industry 30.47% Electrical Appliances 29.22%
Petrochemical General 29.02% Agricultural Machinery 25.90% Food Packaging 16.09%
2. The technical level of leading products in the industry has been significantly improved. With the improvement of various types of mainframes and the growth of joint ventures and cooperation between OEMs and foreign companies, the requirements for matching parts are increasing. Driven by market development, all enterprises in the industry generally attach great importance to technological progress, and actively develop new products with high technical content in response to market demand, and achieved remarkable results. In particular, it should be pointed out that a number of key enterprises have formed a certain scale after the technical transformation in previous years, which plays a decisive role in ensuring product quality and improving reliability.
For example, the three types of valves produced by Beijing Huade Hydraulics Co., Ltd., based on the introduction of technology in the 1980s, have improved and innovated and developed a new generation of series products, the performance has basically reached the level of similar foreign products, and the scale has reached an annual output of more than 200,000 pieces. In 2004, it is expected to reach 300,000 pieces. The hydraulic industry is a high-reliability, high-speed, low-noise power-assisted steering vane pump for passenger cars and trucks. The annual output has reached 700,000 units. Hydrostatic drive units developed by Tianjin Tejing Hydraulics Co., Ltd. and Guizhou Jinjiang Hydraulics Co., Ltd. provide supporting equipment for agricultural machinery. Changjiang Hydraulic Parts Co., Ltd. has developed a variety of load sensing multi-way valves to meet the requirements of energy saving for main engines. The products such as the through-shaft pump and motor produced by Shanghai Teijin Machine Co., Ltd. and Shanghai Sauer Co., Ltd. have greatly solved the matching of high-level mobile machinery and exported them to foreign countries in batches. The new high-pressure column type curved shaft pump developed by Beijing Huade Hydraulic Pump Branch has independent intellectual property rights, the power-to-weight ratio is increased by 30%, and the impact resistance is greatly improved. In order to meet the needs of the mainframe electromechanical integration, the electro-hydraulic proportional valve technology has been relatively mature. In 2003, the output was nearly 30,000 units.
He has made important contributions to the provision of fluid power and control systems for major projects, such as the control system for large gates in water conservancy projects, systems for major projects such as construction engineering, petrochemicals, metallurgical mines, etc., especially for large-scale continuous casting of metallurgical industry. The complete set of hydraulic systems required for the technical transformation of continuous rolling equipment is close to the level of similar foreign products.
There are 6 scientific and technological achievements in the industry that have won the Machinery Industry Science and Technology Progress Award; 58 new products have been rated as excellent new products by the industry association, including 34 hydraulics, 9 pneumatics, 2 hydraulics and 13 seals.
3. The common development of multiple ownership systems in the industry
In the industry, there are enterprises in China that are steadily rising, private enterprises are booming, and the growth of foreign-funded enterprises has shown a three-pronged trend. According to statistics of 283 companies, 62 state-owned and state-owned holding companies accounted for 21.9%. In 2003, sales revenue was 4.88 billion yuan, a year-on-year increase of 22.80%. There were 175 private enterprises, accounting for 61.8%, and the sales revenue was 3.736 billion yuan, a year-on-year increase of 40.75%. There were 46 foreign-funded enterprises, accounting for 16.3%, and the sales revenue was 4.697 billion yuan, a year-on-year increase of 34.57%. The share of sales revenue of state-owned enterprises, private enterprises and foreign-funded enterprises was 37%, 28% and 35% respectively.
Most of the enterprises in this industry belong to small and medium-sized enterprises. Under the support of the state's policy of encouraging small and medium-sized enterprises, they will further develop rapidly. The restructuring of state-owned SMEs will better mobilize the enthusiasm of operators, managers and employees. With the transfer of certain world manufacturing industries to China, foreign-funded enterprises occupy the advantages of technology and operation, and will certainly have greater development at a high starting point in the future.
4î€ The growth rate of foreign exchange earning by export has been accelerated since the 1980s, and there are a small number of exports of liquid and gas tight products. In recent years, the export delivery value has increased year by year, reaching 960 million yuan in 2003, an increase of 72.81%. The most prominent of these is the pneumatic industry, with an export delivery value of 362 million yuan, a year-on-year increase of 110.71%; a sealing industry of 362 million yuan, a year-on-year increase of 57.88%; and a hydraulic industry of 232 million yuan, a year-on-year increase of 53.85%.
Through large-scale international exhibitions in the industry, especially PTC exhibitions, companies have met many foreign manufacturers and played an important role in promoting exports. In 2003, the association organized some enterprises in the industry to participate in international exhibitions in Hannover, Germany. Although the scale is not large, it is very influential. It has won many foreign customers and opened the way for the industry to enter the international market in the future.
III. Outlook and reflection in 2004
Looking forward to 2004, the liquid-gas-tight industry is still a year of vitality and vitality. The nationally determined economic growth target is 7%, and various macroeconomic policies will continue to be implemented steadily, and control of excessively fast investment in fixed assets and blind redundant construction will be controlled. In the macro environment, the machinery industry is expected to grow by more than 10%. According to the understanding of the host industry, the demand for construction machinery is still strong, and it is expected to increase by about 20% in 2004. The automobile industry and the machine tool industry still have a large space for development; the issue of "agriculture, rural areas and farmers" has received special attention from the state, and the agricultural machinery industry will also There is a long-term development. Light industry, electronics, communications and other industries will continue to flourish in the next few years. All of this will bring good development opportunities to our industry.
Judging from the international situation, the world economy is in a mid-term recovery trend, the US economy has seen a significant rise, and the economic situation in other countries has also improved. Since the beginning of this year, the country has reduced export tax rebates, and although there are some adverse effects on the export of products in this industry, the prospects for export are still good.
Looking at the development trend at home and abroad, it is expected that the liquid-gas-tight industry will not fall below 15% in 2004 in terms of the rapid development of 2003. The total industrial output value may exceed 12 billion yuan, and the industry still has its style.
At present, the following issues are worth noting for your reference:
1. In the past two years, many companies in the industry have been full of tasks, and there are many orders. The phenomenon of shortage of supply and the arrival of goods by users has reappeared. Therefore, it is not uncommon to work overtime and neglect management. We must keep in mind the lessons of the past and must not ignore quality issues. Quality is the guarantee of the corporate market. If the market is lost due to quality problems, it will cause irreparable losses. Under the premise of ensuring quality, we will deliver on time, do pre-sales and after-sales service, maintain the image of the company, and create our own brand. 
2. In order to improve the core competitiveness of enterprises, it is necessary to track the demand and development trend of the mainframe in a timely manner, and increase investment in technology development and information construction. Only by making good technical reserves, continuously developing new products with high performance and high reliability that meet the needs of the mainframe, and timely adjusting the product variety structure of the enterprise, can the enterprise be in an invincible position in the competition.
According to the statistics of the customs catalogue (incomplete counterparts), the import of hydraulic and pneumatic sealing products in 2002 was about 500 million US dollars, and in 2003 it rose to 800 million US dollars, an increase of 60%. In the face of a substantial increase in imported products, it is necessary to keep abreast of the trends of imported products and the trend of foreign technology development, and constantly adjust the strategy of the company's own development. At the same time, we must pay attention to the price dynamics of foreign products to prevent damage to our industry caused by unfair competition.
3. After China's accession to the WTO, the rules of trade have become increasingly standardized. Many products in China's liquid-gas-tight industry are products that were digested and absorbed after the introduction of technology in the 1970s and 1980s. Some products have been developed, developed and upgraded. However, due to insufficient investment in science and technology, some self-development capabilities are weak, and some products lack their own intellectual property rights. Some companies carry out the original imitation, even fake and shoddy, to fake the truth. With the further integration of domestic and foreign markets, when these products are circulating in domestic and foreign markets, it is likely to cause intellectual property disputes. Therefore, intellectual property issues must be highly valued by enterprises.
4. The trend of rising prices of steel and raw and auxiliary materials continues, which will inevitably lead to an increase in the cost of liquid and gas tight products. The supporting host industry has repeatedly requested us to cut prices, which will affect the benefits of the industry and enterprises. Therefore, on the one hand, enterprises must tap the potential internally and strive to reduce costs. On the other hand, they need to consider some other corresponding measures.
From the perspective of economic performance in the first quarter of this year, the start is good. The situation in the industry is expected to be optimistic in 2004, but there are also some difficulties and unknown factors. I believe that through the efforts of all employees in the industry, it will present a good year.
