China is experiencing the pain of social change and had frequent emergencies. Every major emergency mixed together with the aggressive game and hit between Party media opinion field and online public opinion field. This article included an empirical research and in-depth interviews based on Shifang event. The result shows that in order to construct the expression spaces and strive for “configuration of strength in the field”, the high degree of distinction and collision become the significant characterization of the communication between two opinion fields in emergencies. According to the view of social identity theory, the curing style and vacuum information with polarized in traditional news reports incur the segmentation, horizontal comparison and conflicts between two opinion filed, which is the sticking point of communication anomie in two opinion fields. These two fields lack of common sense with balance and docking meaning, therefore, the traditional media with authority should build the common sense from the dimensions of cognitive and affective community belief between two opinion fields in emergencies. Also, it can weaken the strength and frequency of emergencies to some extent degrees.
