論屬非控制權益之子公司資產負債對母公司評價之影響

研究目的：本文探討母公司股價對其合併財務報表納入之子公司資產（借款）分屬母公司股東（控制權益）與非控制權益之評價。
研究設計／方法：本文以2005年至2021年台灣上市（櫃）公司為研究對象，利用我國同時提供合併財務報表與個體財務報表資訊估算屬於非控制權益所享有之子公司資產（借款）部分。
研究結果：母公司股價對子公司資產（借款）歸屬於母公司部分給予評價，而對於子公司資產與子公司借款歸屬於非控制權益部分則未給予評價。
研究限制／啟發：本文限制為所估算之非控制權益占比為平均概估值，可能存在衡量誤差。
理論／實務／社會意涵：投資人可正確解讀非控制權益之子公司資產與借款。
創見／價值：本文實證結果支持合併財務報表增加非控制權益資訊附註揭露之規範，有助於投資人評價決策。
