大型企业一般来说专业工种门类多,业务面广,员工多。各个方面、各个层面的教育培训工作多,如:岗位操作资格培训、岗位技能培训、业务培训、企业理念教育培训、继续教育等等,这些培训工作的开展,需要有培训机构来承担。但是,建立自己的培训机构来承担培训还是委托其它专门培训机构开展培训, Large-scale enterprises generally have more types of professional work, more business, and more employees. There are many educational and training tasks in all aspects and at all levels, such as post-qualification training, job skills training, business training, corporate philosophy education and training, and continuing education. These trainings need training institutions to undertake. However, establish their own training institutions to undertake training or commission other specialized training institutions to carry out training.
