Abstract: Public relations management has very important effect on development of enterprises. With the development of modern enterprises, public relations are no longer a way for external drumbeating, but an administrant form an enterprise is pressed for during the course of continuative development. Scientific management of public relations can carve out a way for making popular marks of enterprises, and for scientific management of the inside enterprise. It can reasonably adjust both the relations of enterprise with the outside as a social group, and with staffs in the enterprises.
