本研究之目的在於探討金融商品價值變動、公司特性與盈餘管理之關聯性，研究對象2006年1月1日至2009年6月30日金融業以外之上市公司作，並分為兩部分進行分析。第一部份檢視公司特性與其持有金融商品的關係，並觀察全球金融危機是否會影響公司對於金融商品之持有程度。第二部份探討金融商品價值變動以及公司特性是否會影響公司之盈餘管理行為。
本研究結果顯示，管理當局持股愈高、債務比率愈低、公司規模愈大、現金股利率愈高、流動性愈高以及研發費用率愈高之公司，其持有金融商品之程度愈高。產業為電子業之公司較其他產業之公司持有較少之金融商品。全球金融危機發生之後，公司對金融商品之持有程度有明顯下降之情況。
此外，金融資產評價利益、金融資產評價損失與金融負債評價損失與盈餘管理之關係符合損益平穩化之理論；金融商品減損損失與盈餘管理之關係則符合洗大澡之理論。管理當局持股比率愈高時，愈會將裁量性應計向上操縱或向下操縱，而債務比率愈高之公司，愈會將裁量性應計向下操縱。公司資金愈多，管理階層愈不會操縱裁量性應計，但其差異較不明顯。而電子業公司之盈餘管理幅度則小於非電子產業公司。 / This purpose of this study is to explore the relationships between value changes in financial instruments, firm characteristics and earnings management. The study includes two parts and uses a sample of the companies (excluding financial firms) listed at the Taiwan Stock Exchange from January 2006 to June 2009. First, I examine the relationship between company characteristics and their holdings of financial instruments. It also examines whether the global financial crisis affected these companies’ holdings of financial instruments. Secondly, I examine whether the value changes of financial instruments and company characteristics affect the sample companies’ earnings management behavior.
The empirical results show that the companies with higher management ownership, lower debt ratio, larger size, higher cash dividend yield, higher liquidity, and higher rates of R&D have tend to hold more financial instruments. Companies in the electronics industry hold less financial instruments. Companies kept less financial instruments decreased after the global financial crisis.
In addition, the relationship between valuation gain and loss on financial assets, valuation loss on financial liabilities and earnings management conforms to the theory of income smoothing. And the relationship between financial instruments impairment losses and earnings management is consistent with the big bath theory. Management with higher ownership tends to manipulate more discretionary accruals. Companies with higher debt ratio tend to manipulate discretionary accruals downward. For the companies with more funds, their management manipulates less discretionary accruals, although the difference is less obvious. Earnings management by the companies in the electronics industry is less than those in other industries.
