What are the differences between various talent service organizations?

From the perspective of affiliation, talent service institutions can be divided into two categories: one is the talent service institutions affiliated to the human resources and social security departments, that is, the national talent flow service institutions affiliated to Ministry of Human Resources and Social Security and the talent service institutions affiliated to the human resources and social security departments (bureaus) at or above the county level; Second, the talent service institutions belonging to non-human resources and social security departments, that is, the talent service institutions belonging to other departments of governments at all levels, social organizations, enterprises and institutions and private talent service institutions. The difference between the talent service institutions affiliated to the human resources and social security departments and those affiliated to non-human resources and social security departments lies in that the talent service institutions affiliated to the human resources and social security departments have administrative functions authorized by the human resources and social security departments, and are responsible for all-round personnel agency business such as socialized personnel file management, organizing the application for professional and technical post qualification examination or evaluation, grading and confirming the length of service, accepting college graduates, and introducing talents. Personnel service institutions that are not human resources and social security departments have no administrative functions. With the approval of the human resources and social security departments, they can only engage in one or more intermediary services such as information collection, collation, publication and consulting services of talent supply and demand, talent information network services, talent recommendation, talent recruitment, talent training and talent evaluation.
