隨著國際化的發展,採用全球統一的財務會計準則已成趨勢。財務會計準則第十號公報-存貨之會計處理準則即為與國際接軌而修訂。本研究以台灣上市及上櫃公司為研究對象,選取影響企業財務指標之因素,據以探討企業財務指標與財務會計準則第十號公報修訂之關係。 修正後十號公報修訂重點主要包括不再使用「後進先出法」作為存貨評價方式、評估存貨跌價損失以淨變現價值作為市價之評估基礎、以正常產能為基礎分攤固定製造費用、不再以存貨全體項目作為比較基礎,及跌價損失/回升利益之表達方式修正。 本研究選取台灣上市及上櫃公司四大產業:光電業、半導體業、鋼鐵業及營造建材類。樣本來源為公開資訊觀測站及台灣經濟新報資料庫,研究期間自民國98年第一季至第三季,資料型態符合時間序列(time series)及橫斷面(Cross-Sectional)兩者之特性,故採用panel data模型作為資料分析的方法。 本研究以資產報酬率及Tobin’s Q為應變數,以財務會計準則第十號公報-存貨之會計處理準則修訂對每股盈餘影響數及營業收入變動比率為自變數,其實證結果如下: 1.資產報酬率方面:因實行十號公報對上市及上櫃公司光電業、半導體業、建材營造業及鋼鐵業公司的資產報酬率影響並不顯著。 2.Tobin’s Q方面:實證結果顯示,因實行十號公報對上市及上櫃公司光電業、半導體業、建材營造業及鋼鐵業公司的Tobin’s Q值並不顯著;惟營收成長率對上市及上櫃半導體業公司的Tobin’s Q影響顯著。
To pursue globalization, it has been a trend for firms to gradually adopt the International Accounting Standards. This study chooses the public listed companies in Taiwan to identify Taiwan’s accounting standard No.10 for inventory on operating performance. Key amendments of SFAS 10 are: the last-in, first-out (“LIFO”) inventory flow assumption method was abolished; net realizable value was used to evaluate the inventories; normal capacity was used to allocate fixed production overheads; the use of a group or category of inventories may not be allowed except the criteria provided in SFAS 10 are met; and the modification of disclosure method of “Loss/Gain on inventory revaluation”. This study chooses public listed Optoelectronic, Semiconductor, Iron and Steel and Building Material and Construction industries from the first quarter of 2009 to the third quarter of 2009 to form a whole sample from database of Market Observation Post System and Taiwan Economic Journal (TEJ). This work employs panel data model as a method to analyze data as it fits the features of both time series and Cross sectional. Taking ROA and Tobin’s Q as dependent variables, the influence of SFAS No.10 per share as independent variable investigates whether the implementation of the SFAS No.10 affects the operation ability and profitability of above industries. Empirical results are summarized as follows: 1. Return of Asset(ROA): The influence of SFAS No.10 of the four industries are not significant. 2. Tobin’s Q: Only the growth of Revenue of Semiconductor industry is significant.
