食品安全與全民相關的議題，危機事件會導致組織聲譽的傷害，更嚴重影響民眾的支持行為。本研究利用情境危機溝通理論(Situational crisis communication theory, SCCT)為理論架構，利用實驗法了解其與危機責任、組織聲譽和支持行為之關聯。研究發現，有相關的危機歷史造成組織的危機責任程度比較高，然而，沒有相關的危機歷史，危機責任的程度越小，組織聲譽評價為正面的；一致的危機回應策略，組織聲譽評價為比較正面的；支持行為方面，組織聲譽越好，得到越多支持行為。

In the food industry, any crisis will easily affect the perception and behavior of the public, resulting in a damage of organizational reputation and a loss of public support for the organization. Based on the situational crisis communication theory (SCCT), this study used a 2 (related crisis history: with/without) x 2 (crisis response strategy: consistent/inconsistent) between-group experimental design to explore their relations with crisis responsibility, organizational reputation, and support behavior. Results generally support SCCT. When a crisis occurs, organizations with related crisis history have higher crisis responsibility; organizations without related crisis history have smaller crisis responsibility, and their organizational reputation is positive. Inconsistent crisis response strategies do not have a significant effect on the level of crisis responsibility. However, consistent crisis response strategies can lead to more positive organizational reputation. As to support behavior, organizational reputation is a major factor. Higher organizational reputation can lead to more support behavior.
