摘要


摘要   傳統上的營運績效常以盈餘為基礎的財務比率來衡量(例如:ROA、ROE),但大部分GAAP使用歷史成本來計算報導的盈餘,因此,預期未來營運績效的改變不必然會反映於報導的盈餘中。且因為負債在資產負債表所呈現的帳面值一般是接近其市值,所以相對上會含有較少的衡量誤差。由以上二個理由即可來說明為什麼財務槓桿的改變可以包含不同的資訊,並可合理推測財務槓桿的變動或許也會包含有關營運績效改變的資訊。此外,由於財務槓桿的變動可說是種營運績效改變的前瞻性指標,藉由觀察每年財務槓桿的改變,可以推論是否營運績效已改善或惡化。在營運績效的改變預期會影響股票報酬的情況下,也可以預期財務槓桿的變動將與股票報酬有所關聯。   在本研究中主要乃應用四因子模型及Fama-MacBeth橫斷面檢定來探討財務槓桿變動的資訊內涵,研究期間為自民國77年5月至民國92年4月。而除了採用一般標準財務槓桿的定義外,另外也同時採用融資槓桿及營運負債槓桿來探討在國內的資本市場環境中是否槓桿變動也具有資訊內涵。換言之,本研究為藉由觀察不同的槓桿變動對股票報酬的長短期影響,以探討槓桿的變動是否具有資訊內涵,並進而探討槓桿變動間對長短期股票報酬影響的差異性,以及產業別因素對槓桿變動與股票報酬之間關係的影響。茲將研究結論分別敘述如下: 一、槓桿變動對於股票長短期報酬的影響   由實證結果發現,財務及融資槓桿變動對公司當期的股票報酬有顯著負向的影響,而營運負債槓桿變動則對公司當期的股票報酬有顯著正向的影響,此即各種槓桿變動都是具有資訊內涵的。不過在長期下,各種槓桿變動卻皆是無法對公司的長期股票報酬產生顯著的影響。 二、槓桿變動間對長短期股票報酬影響的差異性分析   根據實證結果,可以得出融資槓桿變動比營運負債槓桿變動對公司長期股票報酬的影響力長之結論。若以影響或解釋報酬的能力來看,融資槓桿變動對解釋公司短期股票報酬的能力仍是大於營運負債槓桿。 三、產業別因素對槓桿變動與股票報酬之間關係的影響   由實證結果顯示,除了營運負債槓桿變動不會因產業別的因素而受影響外,財務槓桿變動及融資槓桿變動均會受產業別的因素所影響,可知產業別的因素的確會對這二種槓桿變動的資訊內涵造成影響,亦即此二種槓桿變動對股票報酬的影響在電子業與傳統產業間是有差別的。

Abstract This study is mainly to explore that whether the changes in financial leverage have information content. Besides using general standard definition of financial leverage, financing leverage and operating liability leverage is also applied to the empirical analysis. To put it differently, by observing the influence of different kinds of changes in leverage on short-term and long-term stock return, this study can examine that whether changes in leverage have information content. Furthermore, I explore the difference of influence of short-term and long-term stock return between changes in leverage. And I also examine the influence of industry factor on the relationship between changes in leverage and stock return. The study shows that:(1)changes in financial and financing leverage have a significantly negative influence on contemporaneous stock return , but the changes in operating liability leverage have a significantly positive influence on contemporaneous stock return. This can conclude that three kinds of changes in leverage all have information content. In the long-term, however, all kinds of changes in leverage cannot have significant influence on long-term stock return.(2)The influence of the changes in financing leverage on long-term stock return is longer than that of the changes in operating liability leverage. On the ability in explaining or affecting short-term stock return, the changes in financing leverage is still superior to the changes in operating liability leverage.(3)Excepting the changes in operating liability leverage, both changes in financial and financing leverage were affected by industry factor. Thus, there is a differential influence of changes in financial and financing leverage on stock return between electronic and traditional industry. It shows that industry factor can indeed affect the information content of these two changes in leverage.
