摘要

本省木質家具業，近年來採購高價位的專用機械愈來愈普遍，期以替代部份人工，藉以降低勞工及操作成本；惟該項設備更新時往往受到折舊方法不同之影響；本研究以直線式折舊法，雙倍餘額折舊法及年數加總數折舊法為基礎，分析在不同的折舊方式下之稅後投資報酬率，作為評估設備更新時之參考。經程式分析結果以採用加速折舊法之雙倍餘額折舊法稅後投資報酬率為最高，年數加總數折舊法之總稅後投資報酬率次之；而以直線式折舊法之稅後投資報酬率為最低。投資計畫進行時設備投資不能超過原訂投資額44.4%，否則稅後投資報酬率將快速下降。工資水準之上昇時對稅後投資報酬率亦會產生很大的影響，宜採加速折舊法進行設備更新並設法降低工資水準上昇之幅度，才能維持一定水準之稅後投資報酬率。

In Taiwan, wooden furniture industry quite often invested a lot of money in purchasing of sophisticated and high value production woodworking equipment in the recent years; in order to substitute some labor and reduce operating cost; but sophisticated equipments are usually influenced greatly by depreciation methods. This study, based on three depreciation methods such as straighted line (SL), double declining balance (DPB), and sum of the-year's digits (SYD) method to create microcomputer program, tried to analyze the rate of return after tax , the result obtained by this study can help to evaluate replacement policy. From the results it showed that double declining balance method had the highest rate of return after tax. In an investment project it would not exceed 44.4% of the original investment, otherwise it would decrease the rate of return after tax greatly. The labor cost also influenced the rate of return after tax highly. The best equipment replacement policy is using the accelerated depreciation method and cut down the labor cost.
