在我們半導體的經濟中,DRAM市場是個有趣的小經濟體。DRAM市場的供應來自於DRAM晶圓廠及設計公司,生產製造流程還涵蓋封裝測試、模組廠。需求則來自PC OEM廠商、消費性電子、通訊應用,也來自於PC的終端消費者,有時候PC OEM、模組廠商及中間商它們也會兼扮供應者及需求者的角色。 DRAM半導體產業在台灣高科技產業中,具有「成本競爭」、「市場價格波動劇烈」、「產業循環景氣明顯」、「世代交替快、產品生命週期短」及「產業與市場型態隨技術發展而快速調整」等五大特性,雖然資金成本高,投資風險大,常使市場投資人望而卻步,然而DRAM的年產值卻又不容小歔,故謹以力晶、茂德及南亞科三家公司作為本研究之對象,並利用其各類公開財務報表為資料來源,且依不同屬性重新區分九大資源,推估未來年度之獲利率、銷貨、週轉率及銷貨,另推估公司市價、帳面價值、本益比及股價淨值比之間的關連性,作為報表使用者不同角度的價值分析工具。
The DRAM market supply comes from the DRAM wafer factory and the design company, the manufacturing flow also covers the seal test, the mold factory. And the demand comes from PC OEM manufacturer, consumptive electronic appliance, the communicatory application, and PC terminal consumers. Sometimes PC OEM, mold manufacturer and the middle man also play the role of the supplier and the demander. The DRAM semiconductor industry in Taiwan has the following characteristics: 1. Cost competition. 2. Fierce fluctuation of market price. 3. Obvious business boom cycling. 4. Quick swift of generation and short product life cycle. 5. Quick adjustment of both market and business pattern with the development of technique. Despite the fact that its high cost and risk make investors recoiling, DRAM’s annual production is hard to ignore. Hence, the study research in Powerchip, ProMOS and Nanya Technology Corporation and use their financial statements as basic data, to distinguish “nine resources” by its attributes, and anticipate profit rate, sales rate, turnover rate and sales in the future; and the correlation of market price, book value, P/E rate and net stock value. This study could be an analytic tool of financial statements from different angles.
