Abstract: The invitation of the management staff, technicians and artisans in the production line of enterprises as the part-time teachers in vocational colleges is an important means of strengthening teaching practice and improving the quality of talent training. And it is also an important path to the innovation of employment mechanism. At present, the construction of part-time teaching staff is slow and facing with a lot of problems. Such staff has not come into the teaching group of vocational colleges. Therefore, the author of this paper suggests that we should make some system of promoting the development of the part-time teachers from the policy level, we should face the whole society and train the “academic and practical” teachers, and establish the pool of young talents. In addition, colleges themselves should make plans of improving teachers' structure,perfect such management of the part-time teachers, promote fusion between outside and inside teachers, and then form a vocational teaching staff with high quality.
