First, the industry production concentration is low. In the worldwide bearing sales of about 30 billion us dollars, the world's eight major multinational companies account for 75% ~ 80%. Germany's two big firms account for 90% of its total, Japan's five for 90% and America's one for 56%. The 10 largest bearing enterprises in China, such as tile shaft, only account for 24.7% of the total sales volume of the whole industry, and the production concentration of the top 30 enterprises is only 37.4%.
Second, the ability of research and development and innovation is low. The basic theoretical research of the whole industry is weak, and the participation in the formulation of international standards is weak, with fewer original technologies and fewer patented products.
At present, our design and manufacturing technology is basically imitated, product development capacity is low, performance: although the domestic host matching rate reached 80%, but high-speed rail passenger cars, high-end cars, computers, air conditioners, high level rolling mills and other important host supporting and maintenance bearing, basically rely on imports.
