企業可能發生的危機種類非常多,包括財務狀況不如預期、產品瑕疵或品質問題、謠言中傷、企業訴訟等,這些危機都可能對公司造成莫大的損失。近年來,危機處理能力與效率已成為管理階層營運的必備能力,且是項不可忽視的重要議題,本研究欲探討處於訴訟案中的被告公司,於被提出訴訟時,採用危機處理形象受損修復策略是否可以降低公司財富的損失。
本研究採用事件研究法,欲探討大樣本的訴訟公司於最初宣告時點,股東財富的變化,透過「訴訟另一方」、「訴訟案由」、「採用的危機處理形象受損修復策略」來解釋公司財富變化的差異。最後對於實證訴訟宣告的被告方公司與原告方公司財富變動差異之因素,可以歸納以下結論:一、被告公司於訴訟宣告日股東財富顯著為負向影響;原告公司股東財富為呈負向變動,但不顯著。二、被告公司在訴訟另一方為政府時,股東財富呈負向變動,公司損失最大;原告公司訴訟另一方為政府時,股東財富呈正向變動,公司利得最大。三、被告公司訴訟案由為公司治理,股東財富為負向變動,且公司損失最大;原告公司訴訟案由為侵專利權,股東財富為正向變動,且公司利得最大。四、被告公司遇上訴訟危機時,採用危機處理形象受損修復策略會降低公司股東財富的損失。
