of VAR model, VAR (7) model of copper prices, VAR (7) model of lead prices, and VAR (5) model of zinc prices were built. Additionally, Granger causality test and impulse response analysis were used to study the co-movement between Chinese and global metals prices. 3.1.1 Granger causality test First, Granger causality test was carried out to the VAR model of copper, lead, and zinc prices......
