人造纖維產業產品為紡織業的主要原料來源，而人造纖維大宗以聚酯纖維與 尼龍纖維為產品的合成纖維為主，而人造纖維產業產品與原料皆與進出口貿易有 相當程度的關聯性，故匯率的觀察也是產業重點之一。故本研究以匯率與各原料 西德州原油、純對苯二甲酸、乙二醇及己內醯胺分別對上市櫃人造纖維產業公司 營運狀況中的月營收以及股價指數報酬作相關係數分析與多元線性迴歸分析。分 析結果顯示，產業的定價能力，會因其匯率與原料走勢改變產品定價;而匯率以 及原料的變動對股價指數報酬率部分，在對人造纖維產業的股價而言，匯率是其 中的考量因素，但非絕對，而原料價格變動才是其主要因素。;The chemical fiber industry products are the main source of raw materials for the textile industry. The main products of chemical fibers are polyester and nylon fibers. The products and raw materials of this industry are related to import and export trade, so exchange rate is one of the key points. Therefore, this study uses exchange rates, West Texas Intermediate crude oil, pure terephthalic acid, ethylene glycol, and caprolactam to analyze the monthly revenue and index of return on stock price of listed companies categorized in chemical fiber industry for correlation coefficient analysis and multiple linear regression analysis. Final results show the bargain power of this industry, it will change product pricing due to exchange rate and raw material. The fluctuation of exchange rate and raw materials has an impact on the index of return on stock price. In terms of the stock price of this industry, the exchange rate is one of the factors but not absolutely the only factor. Instead, the raw material price is the main factor.
