Note:The variables are the same as in Table 1,the number in brackets after variables represents the lag;LogL represents the log-likelihood function value;MVQ(4)represents the multivariate Ljung-Box Q statistic of lag order 4;LM(4),LM(8)represent th
To ensure the validity of the estimation results of VAR-BEKK model,we need to test the stability of different variables included in the model analysis and ARCH effects.The results are shown in Table 1.The ADF method is used to conduct the unit root test on the return series in three markets of soybeans,and the results show that all variables are stationary.The ARCH effect test of lag order 1 and 4 shows that there is ARCH effect in the gains of the domestic and international soybean markets.Therefore,the VAR-BEKK model can be used to model and conduct the volatility spillover effect analysis.
