以往經濟政策不確定性的觀念，只有文字性敘述，沒有量化研究支持，本研究根據斯坦福大學和芝加哥大學的Scott R. Baker、Nicholas Bloom和Steven J.Davis三位學者對經濟政策不確定性一系列量化分析，建構的經濟政策不確定性指數，探討經濟政策不確定性對中國股市影響。
本研究以中國股市為主要研究對象，以2008年4月至2017年8月間上海及深圳證券交易所之A股、B股為研究樣本，運用迴歸分析方法，探究中國及美國EPU指數的月變動率對中國上海和深圳證券交易所A、B股股價的月報酬的關聯性。
經實證結果顯示，中國股票市場與經濟政策不確定性兩者之間具有顯著的負向關聯性，中國經濟政策不確定性的資訊對A股投資者較有影響力，而A、B股同時受美國經濟政策不確定性的衝擊，進而推測出B股投資者對美國EPU的訊息較具敏感性。

In the past, the concept of economic policy uncertainty, only presented by textual narratives, without quantitative research supports, the study is based on series quantitative analysis of economic policy uncertainties made by three scholars of Stanford University and the University of Chicago Scott R. Baker, Nicholas Bloom and Steven J. Davis. They created economic policy uncertainty index to explore the effects of economic policy uncertainty on the Chinese stock market.
The study took Chinese stock markets as the main research object, using the index of A-shares and B-shares of Shanghai and Shenzhen Stock Exchanges from April 2008 to August 2017 as research samples. The study, which using the method of regression analysis, explored the correlations between the monthly changes ratios of EPU(Economic Policy Uncertainty) index in China and in the US, and the monthly remuneration ratios of the A and B shares of Shanghai and Shenzhen Stock Exchanges in China.
The empirical results evidenced significant negative correlations between the Chinese EPU and Stock Markets. The information of Chinese EPU is more influential to A-shares of Shanghai and Shenzhen Stock Exchanges Markets investors, while the A-shares and B-shares of Shanghai and Shenzhen Stock Exchanges Markets were impacted by the American EPU simultaneously, hence the B-shares investors of Shanghai and Shenzhen Stock Exchanges Markets are more sensitive to the information of the American EPU to be speculated.
