     本文應用單根檢定法與自行迴歸條件異質變異數(ARCH)模型,分析民國 80 年1 月至 87 年 8 月臺灣地區豬價及其主要肉品之價格變化。 為瞭解所使用的價格數列資料是 否具有平穩性質,文中首先採單根檢定法檢視時間數列資料是否平穩,並以數列資料的自行 相關函數及偏自行相關函數決定模型之最適落遲階次;其次透過該模型的估計值計算 LM 檢 定量,據以研判國內毛豬及豬肉價格是否存在 ARCH 效果,實證結果顯示樣本觀察期間國內 發生豬隻口蹄疫,已形成較大的價格波動聚集性。  
     An Auto-Regressive Conditional Heteroskedastic (ARCH) regression model is applied to analyze the changes in monthly hog and major pork (loin, shoulder, belly) price data in Taiwan over the period 1991-1998. The empirical results of testing for Unit-Root are used to identify the stationarity of changes in hog and major pork price, and select a suitable lag by means of the partial autocorrelation function. Based on the estimation of ARCH model and the Lagrange multiplier test, this study found that volatility clustering phenomenon of local hog and pork price exists because of foot-and-mouth epidemic outbreak during the sample Period.
