An examination of price integration between stock market and international crude oil indices: evidence from China

This study examines the degree of price integration between aggregate equity market indices of Hong Kong, the Chinese Shanghai and Shenzhen A and B share markets, and the international Brent crude oil price. The application of Vector Autoregressive (VAR) methods reveals that the regions’ markets are generally price-segmented, with the prominent exception of Shanghai B market which is price-integrated with the domestic A share markets in both Shanghai and Shenzhen. The evidence would suggest that Chinese markets are more heavily influenced by domestic events in the long term than external influences.
