Abstract: Tourists public opinion (TPO) is a social phenomenon that tourists recover their perception of unfairness or promote the realization of unfulfilled promises. There is little research on the formation mechanism of TPO with the theories of psychological contract violation(PCV) and opinion field now. This paper attempts to deconstruct the formation mechanism of TPO from the perspective of psychology with the literature review. It analyzes the different influences of individual and group PCV on TPO under the different opinion fields, even obtains the formation and containment mechanisms of TPO. The results show that: (1) the emergence of TPO is a public event caused by the synergistic effect of individual PCV under the influence of public opinion incentives and group PCV with poor governance; (2) Individual PCV will gradually form a vicious opinion field under the stimulus of public opinion incentives and then lead to the formation of group PCV; the synergistic effect of benign opinion field and positive responses can effectively block individual PCV so as to effectively avoid the occurrence of TPO. (3) Individual PCV will not directly induce TPO, and group PCV will cause public opinion events only under the dual effects of vicious opinion field and poor governance. Finally, it puts forward the corresponding strategies based on containment mechanism in order to provide theoretical support and practical guidance for the prevention and control of TPO in the whole society.
