Cheng (2005) 曾經由價值的創造（經濟租）與價值的記錄（保守會計）二構面去討論影響剩餘淨利的因素，他的實證結果顯示，就產業層級而言，產業的超額報酬會隨產業的集中程度、產業的進入障礙以及產業的保守會計因子而增加，就公司層級而言，公司的超額報酬則會隨公司的市佔率、公司規模、公司進入障礙以及公司的保守會計因子而增加。為了瞭解前述的主張是否同樣地適用於台灣，本論文參仿其研究程序，探討經濟租與保守會計因子對於我國剩餘淨利的影響。實證結果顯示，除了公司層級之進入障礙因素外，無論產業層級之超額報酬與公司層級之超額報酬，皆未能隨經濟租與保守會計因子而增加。換言之，本研究認為，後續研究者不應過度單純地使用Cheng (2005) 的發現，相反的，未來研究有必要進一步深入探討適用於我國情況的模型。 / Investigating the impact of value-creation (economic rents) and value-recording (conservative accounting) on residual income, Chen (2005) demonstrates that industry abnormal earnings increases with industry concentration, industry-level barriers to entry, and industry conservative accounting factors. The firm-level abnormal earnings increases with market share, firm size, firm-level barriers to entry, and firm conservative accounting factors. In order to explore whether the previous propositions on the determinants of residual income can be applied in our country, this study examines how economic rents and conservative accounting affect residual earnings in Taiwan. In summary, using Taiwan data, I cannot find evidence to claim that researchers in Taiwan can use Cheng’s findings directly. Therefore, it is worth for future works to explore what factors affect residual income in Taiwan.
