Why can't the development of China's tool industry catch up with the needs of manufacturing?

In the 21st century, China will become the center of world manufacturing. Economic globalization will bring more opportunities and greater challenges to the Chinese machinery industry. The development of advanced manufacturing technology, the adjustment of mechanical industry structure, and the high-efficiency use of high-efficiency CNC machine tools all require modern tools with high efficiency, high precision, high reliability and specialization called "three highs". Obviously, there is still a gap between the current status of domestic Tool companies and this requirement. After the reform and opening up, foreign tool companies entered the domestic market in large quantities, which brought competition to domestic tool companies and brought new technologies and concepts to promote the development of advanced tools. Domestic tool companies are facing increasingly fierce competition and survival and development issues. How do domestic tool companies face competition and how to adapt to the machinery industry?
