Human resource management in the public sector is an activity and process in which the public sector manages human resources within the organization in order to fulfill its responsibilities under the constraints of laws and regulations. Human resource management in the public sector is very important, which should take into account both "public" and "private" values, as well as personal needs and organizational needs, personal goals and organizational goals.

Moreover, because the cost of human resources accounts for most of the cost of the public sector, effective human resources management can reduce the management cost, maintain the vitality of the organization, adapt to the changes of external values and systems, and provide high-quality public products and services for the society and the public.

Human resource training in public sector refers to the training and training of employees' knowledge, skills, abilities and attitudes according to the actual work situation of the organization and the development needs of employees, so as to promote the realization of organizational goals in public sector.

Objectives: Human resource management objectives refer to the responsibilities and achievements that need to be completed in enterprise human resource management. Human resource management should not only consider the realization of organizational goals, but also consider the personal development of employees, and emphasize the all-round development of individuals while realizing organizational goals.

Human resource management objectives include the objectives and tasks of all managers in human resource management, as well as the objectives and tasks of specialized human resource departments. Obviously, the two are different. The goals and tasks of professional human resources departments are not necessarily the goals and tasks of all managers, but all managers generally undertake the goals and tasks that professional human resources departments should complete.
