Stay Machining of mechanical parts Industry ，‘ Enlarge ’ Not necessarily representative ‘ Be strong ’， Although ‘ Be strong ’ First of all, it will show the expansion of market share 。 But the scale is not Be strong The nature of ， Precision machining plant Mainly depends on technical strength 。 Only Be strong State owned Machining of mechanical parts Industry ， Import substitution can become a reality 。 Increase from market share ， Increase to net exports ， And then to the decline of imports ， So domestic Machining of mechanical parts Increase of import substitution rate and net export ， All prove China Precision machining Factory Stay Some areas are Stay Enlarge 。

　　 From Enlarge Reach Be strong ， It's China. Precision machining plant The only way of development 。 The key question is ： Whether Stay Technology-intensive Industry And Industry Substitution occurs in the high added value stage of the chain ？ Whether to move from the downstream to the upstream of the value chain ？ Whether Mastered Machining of mechanical parts Technical ability and ability to innovate iteratively ？ However ， Once China Precision machining plant Stay A certain field becomes the scale champion of global peers ， How to lead innovation has become a new challenge 。

　　 From Enlarge Reach Be strong ， For China Precision machining plant Speaking ， From machinery Parts processing Follower 、 Imitator to leader 、 Role transformation of innovators ， It's also a matter of time 。 Although China Precision machining plant Stay The proportion of low-end manufacturing is already very low ， However, those with high market share Machining of mechanical parts Trade Most of them are of medium low degree Technology-intensive ， In the middle and lower reaches of the value chain ， China Stay Medium height Technology-intensive The market share of manufacturing is not high enough 。

　　 Holistic analysis Machining of mechanical parts Trade ， Stay Integrated circuit 、 High end machine tool 、 Polymer chemical materials 、 Aircraft engine 、 High end mechanical components and other fields still exist Stay Obvious gap ， There are still a large number of instruments and meters that are very dependent on imports ， High end medical equipment and consumables are also highly dependent on imports ， China's jet airliner ARJ21 It's just delivery 。 China Precision machining factory from bigger to stronger Rise ， There is still a long way to go 。
