At present ， China imports CNC precision machining The top ten products are ： Integrated circuit ， Automobile and its parts ， Instruments and Apparatuses ， Primary plastics ， Display panel ， Computer parts ， Copper products ， Medical apparatus and instruments ， Aircraft and aircraft ， Electronic components 。 In addition to low-end industrial products relying on raw materials ， Other numerical control Precision machining The products have achieved the promotion of localization rate 。 China CNC precision machining Substitution of manufacturing for imported industrial products is becoming a trend 。

　　 In technology intensive CNC precision machining Manufacturing industry ， Made in China with high import substitution rate includes ： Electrical equipment ， Automobile ， Transport equipment ， Computer 、 Electronics 、 Optical products ， Chemical engineering, etc 。 In the segment industry ， The high import substitution rate also includes ： Photoelectric technology 、 Integrated circuit 、 Computer Signal communication 、 Aerospace 、 Automobile Spare parts 、 Instruments and Apparatuses 、 Electromechanical equipment 、 Environmental protection machinery 、 Plastic rubber 、 Organic chemistry, etc 。

　　 From the point of view of export China CNC precision machining Manufactured Enlarge ， The results are similar 。 Past ten years ， China CNC precision machining The top industries in the composite growth rate of manufacturing net exports include ： Material Science （ Plastic rubber 、 Material Science Technology ）、 Electromechanical equipment （ Electric machinery 、 Audio-visual equipment 、 Nuclear power ）、 Photoelectric technology 、 Computer Signal communication 、 Traffic Transport equipment 、 Construction machinery, etc 。

　　 From the perspective of import substitution China CNC precision machining Manufactured ‘ Enlarge ’， Use “ The ratio of domestic total output driven by domestic consumption to global total output ” Measuring China CNC precision machining Import substitution rate of manufacturing sectors 。 China CNC precision machining Manufacturing from Enlarge To grow stronger ， There is still a long way to go 。
