The machine tool is the carrier of advanced manufacturing technology and the basic production means of the equipment industry, and is the basic equipment of the equipment manufacturing industry. Among them, CNC machine tools, which are mechatronics equipment, combine the advantages of high efficiency, flexibility, precision, compounding and integration. They have become the mainstream products of the main processing equipment and machine tool market in the equipment manufacturing industry. The level of technology has become an important manifestation of a country's competitiveness. The machine tool is the working machine of the equipment manufacturing industry, providing processing equipment to the downstream industries such as the traditional machinery industry, the defense industry, the automobile industry, the aerospace industry, the electronic information technology industry and other processing industries. In the consumption composition of machine tools, the automotive industry accounts for 35% to 40%, the traditional machinery industry accounts for 25% to 30%, the IT manufacturing industry accounts for 10% to 15%, and the aerospace and defense military and other industries account for 20%. 25%. The automotive industry and the traditional machinery industry are major demand for machine tools. 1. Rapid growth of fixed asset investment in downstream industries The machine tool belongs to the machinery industry, and the machinery industry is closely related to the fixed asset investment of the downstream industry. About 60% of the downstream industry's fixed asset investment is used to purchase machinery products. Therefore, in the downstream industry of the machine tool industry, the main part of fixed asset investment is used to purchase equipment manufacturing tools - machine tools. For example, in the automotive industry investment, more than half are used to purchase machine tools, especially high-precision CNC machine tools. Through statistics, it is found that the growth rate of fixed assets investment in the downstream industry of machine tools is much faster than the average growth rate of the whole society. The traditional machinery industry mainly includes metal products industry, general equipment manufacturing, special equipment manufacturing, electrical machinery and equipment manufacturing, instrumentation and cultural office manufacturing. In the past three years, the average annual compound growth rate of fixed assets investment in general equipment manufacturing, special equipment manufacturing and electrical machinery and equipment manufacturing was 62.75%, 47.71% and 52.69% respectively; in the first 8 months of this year, investment was completed respectively. The amount was 1397.59, 978.31 and 93.638 billion yuan, a year-on-year increase of 55.7%, 56.1% and 44.7%. The communications equipment, computers and other electronic equipment manufacturing industry completed a compound annual growth rate of 29.91% in the past three years; in the first eight months of this year, the completed investment amount was 128.085 billion yuan, a year-on-year increase of 27.6%. 2. Gold cutting machine tools are growing rapidly, and CNC machine tools are growing faster. It is precisely because of the rapid growth of fixed asset investment in the downstream industry that the demand for machine tools has increased rapidly. In recent years, the output of metal cutting machine tools in China has grown rapidly. In the past five years, the annual compound growth rate of gold cutting machine tool output was 23.97%. at the same time, The output of CNC machine tools in China has grown rapidly. CNC machine tools are the mainstream products of the machine tool industry. In the past five years, the average annual compound growth rate of China's CNC machine tool production was 37.39%. In the first eight months of this year, China's CNC machine tool production reached 74,295 units, an increase of 32.3%. The numerical control machine tool is faster than the gold cutting machine tool, and the numerical control rate of the machine tool output is increasing year by year. From the growth rate data, whether it is the overall gold cutting machine tool or the simple CNC machine tool, the growth rate in recent years is faster than before. The machine tool industry is entering a stage of rapid development. It is precisely because the growth rate of CNC machine tools is significantly faster than ordinary metal cutting machine tools, the proportion of CNC machine tool production to the total amount of gold cutting machine tools has increased year by year, and the numerical control rate of China's machine tool output has increased year by year. In 1990, the numerical control rate of machine tool production was only 2.24%, and it increased to 7.96% in 2000. In 2005, the numerical control rate of machine tool output reached a high level of 13.23%. In the first eight months of this year, the numerical control rate of production increased further to 19.05%. . In terms of the output value of CNC machine tools in the total output value of machine tools (the numerical value of output value), it was 26.2% in 2001, 33% in 2003, 35.5% in 2005, and 37.8% last year. Therefore, both the numerical control rate of production and the numerical control rate of output value are rising.
