Researches, in which the state is the subject, considering the power of the state to enact and enforce laws, reveal results that delimit other institutional entrepreneurs in the field and often restrict them in favor of its interests. The purpose of this study is to explain the change, created in a specific organizational field by privatization that is implemented as a policy transfer in which the main actor is the state as a political entrepreneur, by focusing on the actions and strategies of institutional entrepreneurs. For this purpose, in the second part of the study, a theoretical framework is set up by explaining the theoretical approaches and concepts that form the basis of the research, and the theoretical arguments of the research are given by this framework. In the third part, the historical process and application areas of privatization practice about policy transfer are summarized and information is given about the privatization practices in the port industry of Turkey, which constitutes the organizational field of the research. In the fourth part, which comprises the methodological structure of the research, the process of the research method to collect data and to test the theoretical arguments is detailed, by providing the importance, limitations, contribution of the study, the research question, and the presentation of the findings. In the last part called "Discussion and Conclusion", the theoretical arguments of the research are discussed in the light of the findings, contributions are presented and suggestions for future research are listed. At this point, the research is considered to have two main theoretical contributions. The first one aims to fill a theoretical gap by claiming that institutional entrepreneurs create new actor groups that are expected to support them to create a change in the field. The second one intends to make a conceptual contribution to institutional entrepreneurship and institutional work literature by analyzing the actions taken by institutional entrepreneurs during the institutional disrupting process.
