Universal wheel, adjust the foot manufacturer country in relatively scarce capital, labor, relatively abundant factor endowment structure, the priority to the development of capital-intensive heavy industry, industrial casters and endogenous form on the one hand, China's state-owned enterprises is different from other unique properties: with two aspects of the policy burdens, namely strategic policy burden and social burden; On the other hand, China's state-owned enterprises and other modern enterprise principal-agent problems. This determines the simple privatization does not solve the problems facing China's state-owned enterprises reform. Industrial casters backbone of the modern market economy industrial casters, already not proprietorships, instead of the modern large and medium-sized enterprises. Modern large and medium-sized enterprises of separation of ownership and managerial authority, the endogenous to lead to the principal-agent problem between the owner and the operator. Including three aspects: information asymmetry and incentive are incompatible, responsibility, right and so on. Corporate governance task is to solve the problem of principal-agent. And the breakthrough point to solve the problem of principal-agent, to overcome the information asymmetry problem. Because of the incentive incompatibility, responsibility, not the severity of the problem such as, depending on the severity of the problem of asymmetric information. And overcome the information asymmetry problem, requiring companies to fair and equal conditions, sufficient competition in product and factor market operation. Has a long way for building a well-off society, industrial castor industry put forward of the 17th national congress of the comprehensive construction well-off society goal 'industrial casters tool industry faces a difficult task. Industrial casters tool industry has made great achievements, but compared with the advanced industrial countries, the technical level there is still a big gap, science and technology innovation ability is not strong, the basic research and development is still relatively weak, lack of autonomous brand effect. Years high-end CNC industrial casters, processing center, special industrial casters are still a large number of imports, import and export trade deficit with China is very large, its self-sufficiency rate of domestic industrial castor domestic market is still not high; Castor industry at the same time, the industry of the pattern of economic development, the production efficiency and management level, management concept and advanced industrial countries in the same industry, there is still a large gap compared to I make arduous efforts. Currently, to cope with the impact of the international financial crisis, China's government has released the equipment manufacturing industry adjustment and revitalization of planning, according to user requirements, proposed to focus on research and development: compound high speed precision CNC metal-cutting industrial casters, heavy-duty CNC metal-cutting industrial casters, nc special processing, industrial casters, large nc forming stamping equipment, heavy forging equipment, clean and efficient casting equipment, a new type of welding equipment and automated production equipment, large clean heat treatment and surface treatment equipment and so on eight kinds of host products, basic grasp of high-grade CNC device, motor and drive device, CNC industrial castor features, such as key components of the core technology. This is a difficult and glorious task, castor industry has a long way. 15 'early are now in a critical stage, China's accession to the wto negotiations on industrial casters are subject to further opening-up, promised to revise the measures for the administration of import of mechanical and electronic products and scrapped import CNC industrial casters, processing center for import and import license system of examination and approval, lowered import taxes on all industrial casters, the state-owned enterprises in the traditional system. Especially the slash CNC industrial casters, processing center import tariffs. The imported industrial casters in 2005 to 64. $7. 9 billion, more than 18, 2000. The surge in $900 million, 2. 4 times. In 2004 a year in 17 than in 2003. 8. 6 billion dollars. Satisfy the needs of domestic enterprises, but also to promote the economic and trade cooperation with some countries. Continued rapid development during the 11th five-year plan ', the import trade, industrial casters in China imported 2010, 93. $6. 7 billion, more than 2005 in 64. 44 $7. 9 billion, and growth. 57% automotive, aerospace, engineering machinery, electrical, mold and other industry rapid development, led industrial castor needs further expand. Industrial casters import in addition to outside fell slightly in 2007 and 2009 from a year earlier, the other years is growing rapidly. Import growth has: gantry machining center, CNC horizontal lathe, CNC milling machine, CNC tool grinder, CNC gear processing industrial casters, CNC bending machine, CNC plate with transverse shear industrial casters, CNC punch press, industrial casters accessories, CNC equipment, industrial casters parts and tools
