Abstract
As the uncertainty of American economic policy increases, the impact of it on China, a rapidly developing country which is constantly improving its financial market, cannot be ignored. In this paper, we divide China's financial market into eight submarkets, and use the DCC-GARCH model to compare and analyze the volatility spillover effects of U.S. economic policy uncertainty on these different financial submarkets in China from the macro level. Results show that the U.S. economic policy uncertainty promotes China's stock market volatility most of the time, which highlights that the stock market is more vulnerable to the impact of external information. It also turns out that the U.S. economic policy suppresses the volatility of the bond market and money market most of the time, highlighting the hedging function of these two markets to external shocks. Besides, results show that the U.S. economic policy uncertainty has no obvious impact on the volatility of other submarkets.
