企業之股價崩跌對企業本身以及投資人都會造成嚴重的影響，企業之經理人可能因為了私人利益而暫時延後揭露壞消息。在此情況下若企業財務報表品質較差、資訊透明度不佳，於公司有壞消息時管理階層便同時具有動機及機會隱藏或延後公布此壞消息使企業之股價短暫的被高估，當過了某特定時點企業發布壞消息或壞消息累積至一定的程度無法再隱瞞而突然公開時，企業之股價就會有較高的崩跌風險。
財務報表中存有重大錯誤時，代表較差的財報品質且資訊透明度不佳，因此本研究針對財務報表中存有重大錯誤與股價崩跌風險之關係進行探討。由於過去在政治關聯性企業與股價崩跌風險之文獻呈現不一致的研究結果，因此本研究採用與過去研究不同的政治關聯性定義研究其與股價崩跌風險之關係，期望能得出進一步的結論。最後，本研究欲探討重大會計錯誤與政治關聯性之交互影響，以企業當財務報表中存有重大錯誤，且該企業具有政治關聯性時，是否會有較高之股價崩跌風險進行研究。
研究結果發現，以NCSKEW_F1作為股價崩跌風險之衡量時，企業財報中存有重大錯誤時股價崩跌風險較高，表示當財務報表中有重大錯誤時代表財務報表品質較差，無法有效地降低內部人與一般投資人之資訊不對稱問題，財務資訊透明度較差，企業會有較高之股價崩跌風險。在企業之政治關聯性方面結果顯示，以NCSKEW_F1作為股價崩跌風險之衡量時，具政治關聯性企業可能有較高之股價崩跌風險。最後，本研究未發現當企業財務報表存有重大錯誤且此企業具政治關聯性與股價崩跌風險之關係。
