Because of mechanical foundation for an important position in the machinery industry are familiar with the late, long-term lack of investment, resulting in the entire industry infrastructure is poor, weak economic foundation and strength of the weak. With the improvement of China's extraordinary is the host level, mechanical foundation bottlenecks behind the hosts increasingly apparent. In recent years, although the introduction of technology, technological innovation, research and development, the country has given some support, but compared with the current market demand and foreign level, there is still not a small gap, in particular in: less product variety, low level, quality of instability, early failure rate, poor reliability. China Machine Components product variety, size small, extraordinary gap between the larger high-end products can not meet the growing needs of the host. Currently, the performance of various types of host-based member of the 20th century, roughly equivalent to the level of foreign 1980s. Quality of instability, early failure rate, poor reliability, is the Achilles heel of the foundation member. Therefore, many OEMs to improve the market competitiveness of its host, often choose to import basic parts support, resulting in domestic basic parts, the extraordinary low-tech products, the domestic market share declined. Although China's exports of basic items has obvious advantages, but mainly labor-intensive products, a large number of low-value, high technical added value. Currently, the presence of mechanical basic parts industry following major issues: First, serious overlapping, low degree of specialization, not form scale, economic efficiency mechanical basis compared with the host enterprises to establish the initial financial and technical inputs required relatively less so in a period of several economic development of the country, have increased the number of basic parts production enterprises, and with it the emergence of a large number of low-level redundant construction, and more, in small quantities, do not form economies of scale. Basic parts business, while gradually independent of the OE, but most companies is itself large and small but complete, low degree of specialization, the equipment level is not high, unstable quality, low economic efficiency. China's bearing industry as the sum of the three large backbone enterprise with an annual output of bearing a famous company less than 50 foreign countries. The past two years, hundreds of built hydraulic factory, but only a few annual output of more than 300,000, mainly agricultural products is supporting. The annual output of Germany Rexroth hydraulic items 1.3 million, Yuken Japan has an annual output of 600,000 or more. Industrial countries die enterprise value of about US $ 150,000 per capita to 200,000, only 40,000 of ~ 50,000 yuan. In recent years, along with a variety of common ownership of development policy, the basic parts industry is undergoing intensive development process by dispersing gradually concentrated. Second, research and development is weak, insufficient capital investment, technological progress is slow basic parts of various industries in the late 1970s and early 80s to early introduction of a number of foreign advanced technology, but the lack of adequate absorption of hardware and software investment . According to foreign experience, technology and funds needed for digestion and absorption ratio of about 1: 7, and our late this familiar, slow pace of digestion and absorption. Market competition is actually a technical strength of the contest. Abroad are extremely seriously, have increased investment, occupy high ground. Major funding for scientific research and development company known for its sales account for 4 to 5, up to 10 focus areas. At present, China Although many colleges and universities engaged in research work, a lot of theoretical research, scientific research, patents, papers have a very high level, but the combination with the actual production is not tight, the extraordinary is transformed into commodities slow.
