In the world of highly developed science and technology, mechanical engineering advanced levels restrict productivity, and decide a nation comprehensive strength to a certain extent. In order to let public to be clearer about Chinese mechanical engineering current research progress and future outlook, the paper firstly makes simple introduction on Chinese mechanical engineering, analyzes Chinese mechanical engineering current development status in every field. That is Chinese mechanical engineering has been greatly developed in every field, but some fields development is good, while others development is slower. And then according to analytic hierarchy process, in case considering progressiveness, practicability, safety and contribution as well as other influence factors, it gets Chinese mechanical engineering future development key points contents occupied proportions that is to further implement mechanical artificial intelligence, and relative filed professional integration and each field mechanical’s integration of mechanical and electrical in every field, and their proportions are respectively 0.344, 0.314 and 0.342. Therefore, it is clear that Chinese mechanical engineering future development trend is relative stable, and moves forward correct directions, is beneficial to Chinese such field modernization construction and development.
