The intelligent manufacturing is becoming a commanding height in the new round of industry competition. Led by German Industry 4.0 （Germany），the Industrial Internet （USA），a number of countries have been actively plotting how to utilize advanced manufacturing technologies，information and communication technologies and the powerful advantage of manufacturing industry，so as to build the new engine of manufacturing industry competition in an era of informationization. Looking into Industry 4.0 and the Industrial Internet，the kernel of taking up the commanding height in a new round of industry technological changes is consistent，which emphasizes the interconnections between human and human，human and machine，machine and machine，service and service，reinforces the lateral，longitudinal and end-to-end highly integration，based on the data as the core concept of revolution，and deploys enhancement of technology research and development，the standards，the industrial application，the talents cultivation，in order to improve the level of digitalization，networking and intelligent manufacturing. This paper displays and analyzes the core elements，development situation，problems and trends of intelligent manufacturing，by tracking global development of intelligent manufacturing，such as new trends and new results.
