Hong Kong newspaper Apple Daily began to publish in Taiwan on May 2, 2003. Many Taiwan newspaper journalists show their worry about the pure business management way of Apple Daily will result in the retrogression of journalistic professionalism in Taiwan's newspaper industry. Through the literature review and case study of Apple Daily, this study finds business logic and journalistic professionalism don't repel each other absolutely. In some aspects, business logic can even improve the fulfillment of journalistic professionalism. The critical discourse of Apple Daily is a selective critic. People who criticize Apple Daily emphasize the bad influence of Apple Daily, but ignore her possibly positive contributions. This can be considered as a collective resistance of other newspapers and they try to weaken the legitimacy of Apple Daily, and it is supposed to be one kind of competitive strategy.
