Guide: the current situation of China's long-term dependence on imports of major technical equipment of mechanical engineering has been perplexing the industry. According to statistics, in 2003, the inverse difference between the import and export of mechanical products reached 39.239.5 billion US dollars, and the total import increased by 50.91% year-on-year. Experts from the major equipment project office of China Machinery Industry Federation said that it is indeed

the industry has been plagued by the long-term dependence on imports of major technical equipment of mechanical engineering in China. According to statistics, in 2003, so that the experimental data were accurate, the inverse difference between the import and export of mechanical products reached 39.239.5 billion US dollars, and the total import volume increased by 50.91% year-on-year. Experts from the major equipment project office of the China Machinery Industry Federation said that for products and equipment that do not really master the technology at home or have a large gap with the foreign level, we should adopt the policy of exchanging the market for technology, and promote foreign companies to cooperate with domestic enterprises to transfer technology to Chinese enterprises through bundled bidding

in terms of market for technology, the "Three Gorges model" is a successful model. In June 1996, when the bidding document for 14 units on the left bank of the Three Gorges project was issued, we asked the bidder to jointly design and manufacture with Chinese qualified manufacturing enterprises, and transfer technology to Chinese manufacturing enterprises; The share of Chinese manufacturing enterprises shall not be less than 25% of the total contract price. The latter two units are mainly provided by Chinese manufacturing enterprises. Chinese experts said that the introduction of technology, subcontract manufacturing and technical training are important links for Chinese enterprises to master the introduction of core technology; In the tender for technology transfer, the foreign party is required to transfer the design source program, so as to really learn the technology through foreign technology transfer; During the implementation of the project, Chinese enterprises can send personnel to participate in testing, joint design and technology transfer training; After the transferred software installed on the computer that can be stored, printed and displayed with a relative error of ± 1% has reached the same calculation results as those abroad, has been used smoothly for one year and has been accepted, China will pay the technology transfer fee. Through this model, on the basis of tackling key scientific and technological problems of the Three Gorges unit, the two Chinese enterprises have better digested the imported technology and have the ability to independently develop, design and manufacture large hydropower units. It is reported that the core of the application of the "Three Gorges model" is to rely on the introduction of technology and cooperative manufacturing of engineering projects, so as to speed up the development of major technical equipment in China. Of course, the current industrial situation has put forward higher requirements for the introduction mode

according to the mechanical and economic data of the Machinery Industry Federation, in the main industries of mechanical products, except agricultural machinery, electrical appliances and food packaging machinery, other major industries such as instruments and meters, engineering machinery, machine tools, heavy mines, internal combustion engines, petrochemical general and basic mechanical parts are trade deficits. On the one hand, the increase in the import of mechanical products reflects the stable development of macro-economy. On the other hand, it also shows that there is still a large gap between the domestic machinery manufacturing industry and the international level, because many products imported by China are still unable to be produced by domestic enterprises. Sui Yongbin, special member of the Machinery Industry Federation, pointed out for example that a large number of construction machinery such as concrete distributor, concrete lining machine, maintenance trolley and working bridge required in the South-to-North Water Transfer Project are produced by domestic enterprises without mature experience

mechanical products rely heavily on imports. In addition to the fact that the technology and quality of domestic enterprises can not meet the requirements, some manufacturers only focus on immediate interests and despise research and development is also an important reason. Taking the machine tool industry as an example, a technician of an automobile company pointed out that with the continuous improvement of the automobile level, the requirements for special precision machine tools are becoming higher and higher. However, the compound annual average growth rates of the production capacity of boring cylinder bore, curved polycarbonate (PC) and polybutylene terephthalate (PBT) are 116.5% and 23.9% respectively. The special precision machine tools used in key auto parts such as shaft bore and cylinder head seat guide pipe have many varieties, small batch and high technical requirements It is difficult to develop. Many machine tool enterprises have given up R & D, resulting in a serious shortage in the domestic market and have to rely on imports. "For heavy machinery products that are urgently needed by the country but can not be mastered in China at present, with long development time and high investment cost, market for technology is a good model." Sui Yongbin pointed out, "of course, some technologies cannot be exchanged by the market. For example, China passed 23 sets of bundled bidding in 2002, which enabled the foreign party to transfer 75% of the manufacturing technology, but the design technology cannot be transferred." He said that on the one hand, Chinese enterprises should strengthen all aspects of cooperation with advanced international enterprises; On the other hand, we should change from passive to active, strengthen independent R & D capacity and improve the technical level. Only in this way can we completely change the situation of China's dependence on imports of heavy machinery and equipment
