本研究旨在探討臺灣總體經濟變數、基本面因素及國內外股價指數對於電子類股股價間之關聯性。研究期間為2005年7月1日至2015年6月30日期間之月平均股價,每個變數均具有120筆月資料,資料主要來源為臺灣經濟新報(TEJ)。採ADF 單根檢定、Johansen共整合檢定、向量自我迴歸分析、Granger因果關係分析、衝擊反應分析及向量誤差修正模型等方法進行實證分析。實證結果顯示: (1)由衝擊反應函數可得知,商業本票次級市場利率、金融業隔夜拆款利率及一年定期存款利率,對電子類股股價之影響較持久且為正向;而臺灣同時指標綜合指數及失業率,對電子類股股價之影響較持久且為負向影響。 (2)由變異數分解結果可得知,解釋電子類股股價能力最高之前三名變數,依序為臺灣股價加權指數、費城半導體指數及紐約史坦普爾500股價指數。 (3)由VECM 模型檢定得知,失業率與電子類股股價脫離長期均衡關係時,主要由失業率來進行調整。而當外資交易金額比重與電子類股股價脫離長期均衡關係時,主要由外資交易金額比重來進行調整。
This research aims at discussing the correlation between the macroeconomic variables,fundamental factors,foreign and domestic stock price indexes and the electronics stock prices. It studies the monthly average stock prices from July 1,2005 to June 30,2015; each variable has 120 monthly data, which are mainly from Taiwan Economic Journal (TEJ). It conducts the empirical analysis using ADF unit root test,Johansen co-integration test,vector auto-regression model,Granger causality test, the impulse response test and the vector error correction model. Empirical results show: I. It can be known from the impulse response function that the secondary market interest rate of the commercial paper,interbank call loan rate and one-year fixed-term deposit interest rate have lasting and positive effects on the electronics stock prices; Taiwan’s coincident index and unemployment rate have lasting and negative effects on the electronics stock prices. II. It can be known from the variance decomposition result that the top 3 variables that can explain the electronics stock prices are weighted index,PHLX semiconductor index and Standard & Poor’s 500 Index in sequence. III. It can be known from VECM Model Verification that when the unemployment rate and the electronics stock prices breaks away from the long term equilibrium relationship,the adjustment is made mainly through the unemployment rate. When foreign deal value proportion and the electronics stock prices breaks away from the long term equilibrium relationship,the adjustment is made mainly through the foreign deal value proportion.
