Privatization of public enterprises has been going on for the last few years, since privatization is taken as the panacea for those poorly managed public enterprises. On the contrary, direct transplant of privatization from developed countries to Taiwan have resulted in some serious problems during the implementation. Chunghwa Telecom is one of the few large-scale public enterprises in Taiwan, which owns branch offices nationwide. Therefore, the privatization of Chunghwa Telecom is seen as a pilot model of public enterprise privatization in the country. However, there existed many conflicts and confrontations during the process of privatization in this case. Privatization may not seem to be the most effective way to save public enterprises. Based on public choice theory, this study intended to discover the effectiveness as well as the advantages and disadvantages of Chunghwa Telecom privatization through literature review. Next, this study attempted to indicate the method of Chunghwa Telecom privatization, the major differences between before and after the privatization, as well as the obstacles during the privatization. Finally, this study planned to find out the possible causes of the obstacles during Chunghwa Telecom privatization, then to propose solutions for the problems. This study found that the major obstacles during Chunghwa Telecom privatization result from unions and the sale of stock shares. Due to lack of trust and fear of loss of their interests, most employees of Chunghwa Telecom did not support the privatization. In the absence of internal support within the organization, the success of reform is extremely rare. In addition, the sale of Chunghwa Telecom stock shares was quite unsuccessful, which critically delayed the completion of its privatization. This study suggests that, in order to reduce the internal resistance during the privatization, the government has to establish corresponding regulations to protect the benefits and rights of employees. Moreover, in order to obtain the trust and support of employees, the government needs to promote privatization through various marketing strategies. Once employees are willing to support the reform in the Organization, the organizational changes will succeed. The experience of Chunghwa Telecom privatization actually gives the government a good lesson of public enterprise privatization. If it is implemented properly, privatization is still an effective approach to improve the operating performance of public enterprises.
