The civil service system itself is the result of the classified management of the whole cadre and personnel system, which divides the whole cadre and personnel into organs, enterprises and institutions. However, civil servants should also be classified. On the basis of summarizing the implementation experience of the provisional regulations, the Civil Service Law clarifies the basic principles and guiding ideology of classified management. It is stipulated that the state shall implement the post classification system for civil servants.
At present, all civil servants, regardless of category, use a management model, and promotion and salary are the same model, which is not conducive to mobilizing the enthusiasm of civil servants and scientific management. Therefore, from the actual management needs, according to the characteristics, nature, management needs and the law of talent growth, the civil service law is divided into comprehensive management, professional technology and administrative law enforcement, and each category adopts different management methods. Civil servants engaged in professional and technical work take professional and technical posts, which provides a career development ladder for civil servants engaged in professional and technical work, in order to attract and stabilize the indispensable professional and technical personnel of the organs, and encourage them to stand on their posts and become experts in their own work. The establishment of administrative law enforcement posts mainly reflects the guiding ideology of leaning to the grassroots level, which solves the outstanding problems of narrow career development space and difficult job promotion of civil servants in grassroots law enforcement departments, encourages front-line law enforcement civil servants to do their jobs better, and is also conducive to strengthening the management and restraint of front-line law enforcement civil servants.
In addition, for special personnel, such as judges and prosecutors, their obligations, rights and special management requirements are embodied in the Judges Law and the Prosecutors Law. In addition, according to the working characteristics of the people's police, customs and civil servants in foreign diplomatic institutions, the state sets ranks corresponding to their posts.
