ISO 14001環境管理系統認證為最根本且廣泛使用的國際標準,然而位處開發中國家的台灣上市櫃公司於實施環境管理系統且獲得ISO 14001認證後,是否能夠為企業帶來實質上的財務效益?本研究分別從收入、成本、獲利三方面探討通過ISO 14001認證短長期對企業財務績效之影響為何,並進一步分析「環境敏感度」、「耗能程度」、「CSR受重視程度」之特性不同的公司,其通過認證所獲之財務績效是否有所差異。 本研究實證結果支持本研究三項研究假說,說明企業通過ISO 14001認證短期內之銷貨成本率顯著增加;長期來看,通過認證後經過四年其銷貨成本率增加幅度有降低情況、收入及獲利面財務指標具顯著正向影響,並進一步發現,環境敏感度與CSR受重視程度之特性對認證效果具有長期之正面效益。
