With the release of demand for product upgrading and the introduction of "revitalization plan" and "major special" policies, the machine tool industry will have structural recovery opportunities. The machine tool industry still has a lot of room to grow in the future. China is currently in the middle and later stages of industrialization. Seen from international historical experience, the most important feature of this stage is the acceleration of the upgrading of manufacturing equipment, and the proportion of enterprise equipment investment in fixed assets investment will gradually increase. On the other hand, from the international comparison, the scale of China's machine tool industry is still relatively small compared with the downstream industry, so the machine tool industry has a lot of room for growth in the future. After entering the 21st century, China's machine tool industry has maintained a good situation of rapid development for 8 consecutive years, and has become the world's third largest machine tool producer in terms of scale and output value for 4 consecutive years. But at present, most of China's high-grade CNC machine tools rely on imports of the situation is still not broken, domestic CNC machine tools with low added value of simple economic CNC machine tools accounted for nearly 70%, and imports are with high added value of high and middle grade CNC machine tools, foreign companies occupy about 85% of the market share of China's high-grade machine tools. To this end, the machine tool industry has formulated a three-year revitalization plan: after three years of development, the domestic market share of machine tools increased to more than 70%, including CNC machine tool share increased to more than 40%. In the machine tool industry to reverse the trend of the same time, China's machine tool low-end dogfight high-end loss will still exist, this is also the need to solve the problem. The world machine tools into the era of NUMERICAL control, producer, consumer concentration is high: machine tools can be divided into ordinary machine tools and NUMERICAL control machine tools. CNC machine tools are developed on the basis of ordinary machine tools, first of all for the needs of military industry, followed by civil machine tool performance requirements to improve the development of CNC machine tools. At present, the world machine tool presents the form of the United States, Europe and Asia, and the United States, Germany, Japan as the representatives of the three continents.
