In recent years, the Taiwan¡¦s TV talk shows about the political topic have a bias in favour of party. In Taiwan, there are two property of party, one is called Blue property of party, the other is called Green property of party. In order to get more audience rating, theTV stations make the program by the means of antagonism. In this background, it becomes more important that audience how to response the genus of TV program. In order to investigate the phenomenon, we use two main directions. One way is stimulus response, it assumes the audience is influnced by TV progarm. In this way, we apply the broaden-and-build theory of positive emotion. The other way is audience¡¦s subjectivity, it assumes that audience can reflex what TV program want to talk to them. In this way, we apply the political philosopher-Hannah Arendt¡¦s doctrine. We found that audience¡¦s emotion be influenced by TV talk show, and no matter what party identification they belong to, most emotions are negative. But, when the TV talk show has a bias in favour of party which is the same with their party identification, they have moer higher positive emotion than which is no the same. And when the TV talk show has a bias in favour of party which is not the same with their party identification, they have moer higher positive emotion than which is no the same. But we can¡¦t justify the the broaden-and-build theory of positive emotion. No mater what party indentification they are and no matter what TV talk show of property of party they watch, we can¡¦t found obvious subjectivity of audience. It¡¦s a crisis of public sphere.
