The study aims to examine the security of Taiwan’s media system. Its main hypothesis is that the People’s Republic of China is pursuing a deliberate strategy of influencing Taiwan’s media at various levels by a range of means. Some authors refer to this approach as the commercialization and outsourcing of censorship and propaganda. The approach has had the effect of routinizing self-censorship. Research questions are also asked about the methods and strategies adopted by China to influence Taiwan’s media, including the commercialization and outsourcing of propaganda. The idea is to ‘hire’ various state institutions and agencies or their subordinate organizations, commonly from the private sector and from third countries, to deliberately disseminate and endorse views and ideas aligned with China’s interests. The strategy can be described as an invasion of sorts that is not of a coercive and/or external nature but rather is performed from the inside, aimed directly at the hearts and minds of the country’s citizens. The paradox is that democratic media systems that protect freedom of speech are more vulnerable to this strategy. An attempt is made to demonstrate that the ‘China factor’ is increasingly present in Taiwan’s media landscape. Its effectiveness may have grave consequences not only for the me- dia system itself but also for the political system of the Republic of China (Taiwan) in general. In addition, the article seeks to identify the most appropriate and effective strategies and means for countering and combatting such threats. In drafting this article, a range of research methods were employed, including that of inductive and deductive inference, the historical method (used to outline the historical background behind significant social and political transformations in Taiwan), the institutional and legal analysis method (used to explore the influence of institutions on specific social phenomena), the legal text exegesis method as well as the statistical method (to describe Taiwan’s media system).
