The main conclusions are as follows: first, the ADF test shows that at the 1% significant level, the CSI 300 stock index and its futures trading data are integrated of first order; second, E-G co-integration test and the ECM model show that, a long-run equilibrium relationship exists between the 300 stock index and its futures, and the readjustment of stock index futures on the deviation of spot price from the long-run equilibrium is -0.69840; third, the GARCH model shows that the CSI 300 stock index futures significantly exacerbates the volatility of the CSI 300 index, and the impact of new information on market volatility has weakened while that of the old message has gradually increased; fourth, Granger causality test shows that the CSI 300 stock index and its futures mutually guide each other and stock futures has a more powerful guidance on futures.
