本研究運用共整合分析、向量誤差修正模型及狀態空間模型等多項時間序列研究
方法針對國際股市、債市與景氣循環間之動態關聯性進行實證分析。研究結果發現：
一、藉由長期均衡關係分析得知，在台灣與歐元區金融市場中皆呈現不具有共整合關
係存在，這表示台灣與歐元區金融市場間並沒有長期穩定的關係存在；而在美國金融
市場中則顯示具有共整合關係存在。二、藉由短期互動關係得知，(1)美國金融市場之
中，美國股市單向領先美國公債，而且美國股市與美國景氣呈現雙向回饋之關係。(2)
歐元區金融市場之中，歐元區景氣單向領先歐元區公債，而歐元區股市與歐元區景氣
呈現雙向回饋之關係。(3)台灣金融市場之中，台灣景氣影響台灣公債，亦即台灣景氣
領先台灣公債。由此發現可知，投資者無論於何種經濟區域皆可藉由債市指標推測景
氣指標。
