At present, vocational college education focusing on the education level of talent training, however, it ignores the needs of workers’ vocational training based on enterprise development planning and training of professional career development. Therefore, we should strengthen the connection between vocational training and vocational education. For the establishment of modern vocational education system, we should enhance the value of human capital of workers in order to adapt to the new economic norm with important practical signifi cance.展开更多
