Abstract
This paper investigates the interactive relationships among China energy price shocks, stock market, and the macroeconomy using multivariate vector autoregression. The results indicate that there is a long cointegration among them. A 1% rise in the energy price index can depress the stock market index by 0.54% and the industrial value-adding growth by 0.037%. Energy price shocks also cause inflation and have a 5-month lag effect on stock market, which may result in the stock market "underreacting." The energy price can explain stock market fluctuations better than the interest rate over a longer time period. Consequently, investors should pay greater attention to the long-term effect of energy on the stock market.Entities:

Note. 1The meanings of various variables in the table are as follows: IP is industry value added discounted by price index, OIL is discounted purchase price index for fuel power, R stands for real interest rates, and STOCK is monthly price index of Shanghai stock market.
2 c, t, and p in test type stand for constant, trend, and lag orders, respectively.
3At three remarkable levels, when ADF value is greater than critical value, corresponding series has unit root.
4 ***, **, and * stand for 1%, 5%, and 10% critical levels, respectively.
5 d stands for the first differential of the variables, and d 2 stands for the second differential of the variables.
