This text attempts to make a grasp of publicness maintained by Chunghwa Telecom Co. before and after the change of system through an analysis and comparison of the related literatures, along with having an understanding of the issue if there leads to difference for the content of its organizational structure as well as the personnel appointment and promotion. The research findings are: 1. Even though it takes the method of “public internalization” to achieve the public purpose ensured before and after the change of system, responsibility of supply for the publicity of telecommunication enterprise is borne jointly by the relevant traders instead of by the telecommunication traders; 2. With the amendment or institution of related law and regulation, Chunghwa Telecom Co. has gained a greater power of self-management on operation, personnel and finance; 3. On the way of a shift to privatization for Chunghwa Telecom Co., the design of organization has presented a stronger focus on professionalism, functionality and division of work, that would further make a response to the demands on outer environment elastically. But there are still over 4/5 of employees in Chunghwa Telecom Co. are entitled the governmental-employee status which may be a little bit excessive for one company which has shifted to privatization, that would thus affect the efficacy of reform.
