The innovation of generic technology for the development of the manufacturing sector has an important basic role, and for the generic technology research and development, there is lack of effective attention. Especially in manufacturing industry, the development of generic technology still can't meet the national economy and the needs of the development of manufacturing industry. Especially compared with foreign countries generic technology innovation development and application there is a considerable gap .On the basis of introducing the classification and features of manufacturing generic technology, this paper analyzes the influence factors and main body of generic technology innovation in the manufacturing industry. Finally, it derived the process model of manufacturing generic technology innovation from the process model of manufacturing technology innovation.
