本研究利用MGARCH-DCC模型,探討新台幣升值對台灣上市工具機公司1515 力山、1528 恩德、1530 亞崴、1532 勤美、1539 巨庭、1540 喬福、1583 程泰、1589 永冠-KY、1590 亞德客-KY、2049 上銀、4510 高鋒、4526 東台、4533 協易機的MGARCH風險溢酬評估分析。研究期間自2018年01月01日至2021年03月19日,共778筆日資料。資料來源為台灣經濟新報。實證結果發現,新台幣及台灣上市工具機公司股價指數日報酬資料皆顯著拒絕虛無假設,表示新台幣及台灣上市工具機公司股價指數報酬資料具有變異數為異質變異數。通過MGARCH-DCC模型分析,具有DCC效果。
This study principally adopts the method of application of MGARCH_DCC Models, to discuss the appreciation of the New Taiwan dollar on the MGARCH risk remium assessment analysis of Taiwan's listed machine tool companies, including 1515 Lishan, 1528 Ende, 1530 Awei, 1532 Qinmei, 1539 Ju Ting, 1540 Qiao Fu, 1583 Cheng Tai, 1589 Yongguan-KY, 1590 Airtac-KY, 2049 Shanghai Silver, 4510 Gao Feng, 4526 Dongtai, 4533 SEYI. The research time from January 1, 2018 to March 19, 2021, totally of 778 daily records were collected. The source of the information comes from Taiwan Economic Journal.
