1) Non-public refers to an organization or individual that neither affects the subject of public relations nor is affected by it. Simply put, they do not belong to the current "public relations object" of the public relations subject. Non-public opinions, attitudes and behaviors are not influenced by the organization, nor do they have any influence and consequences. So this kind of public can be excluded from public relations work. From the specific public relations point of view, non-public does not constitute the public relations object, and the target public of a specific organization can only be specific and clear. Individuals, groups and organizations that have nothing to do with the subject of public relations can only be non-public. Of course, both organizations and the public are changeable, so the relevant public and non-public are relative and can be transformed. With the change of time, place and conditions, non-public may be transformed into potential public. The focus of this division is to clarify the pertinence of public relations work, so as to maximize the benefits of the limited manpower, material resources and financial resources of the organization and avoid the blindness and waste of public relations work. 2) Potential public Potential public refers to organizations and individuals that will have an impact or be affected by the subject of public relations, but they are not clearly aware of it. In other words, they are not the public relations objects of the public relations subject today, but they may become the public relations objects of the public relations subject tomorrow. Due to the behavior of the organization, the public objects that may have an interest in the organization in the future. Aware of the existence of potential public, it is conducive to the organization to formulate targeted public relations strategies, but also conducive to the organization to adjust the policy behavior of the real public. The role of potential public can not be ignored, it is an important object to shape corporate image. If an enterprise develops a new product, it will attract more potential public. The task of shaping corporate image is to take a series of measures to attract the attention of this part of the potential public and make this part of the potential public become a real public as soon as possible.
3) Knowing that the public knows that the public refers to the public (organization or individual) who has been or has influenced the subject of public relations but has not yet put it into action. Knowing that the public has basically made clear the nature, development trend and impact on their own interests, they began to pay attention to seeking relevant information and conceive corresponding countermeasures, but they did not take corresponding actions. They are waiting for the development of the situation and decide their own direction of action according to the development direction of the situation. Their behavior may be good or bad for the organization. Therefore, the public relations department should adopt a positive public relations attitude, actively respond and communicate, meet the public's informed wishes and requirements, make public organizations feel trusted, and control the public opinion situation at the same time. Especially for those public behaviors that may be unfavorable or harmful to the organization, we should take timely preventive measures, take the lead in public relations, communicate in time, clarify problems, resolve doubts, seek understanding, and prevent contradictions from expanding.
4) Behavior of the public Behavior of the public refers to the public (organization) that recognizes the problems between subject and object and takes action on them. Simply put, the public has bought it with the public relations subject. The existence of the action public is conducive to the survival and development of the organization. There is a close relationship between the organization and the public, and the two sides have formed a relationship of full understanding and mutual trust, showing a seamless connection between the organization and the public. Open action is not conducive to the survival and development of the organization. In this case, the publicity of actions is often related to emergencies or public relations disputes. If it is not handled well, it will cause direct pressure or threat to the survival and development of the organization, or it will cause great difficulties and bad effects to the organization.
