 Normal and abnormal information transmissions: evidence from China's stock marketsChien-Liang Chiu and Jui-Cheng Hung Applied Economics Letters, 2007, vol. 14, issue 12, 863-870 Abstract: This article investigates normal and abnormal information transmissions by examining diffusion volatility and jump intensity spillovers in China's stock markets. We analyse the impact of releasing investing restriction to information transmission mechanism, and also the interactions between 'A' and 'B' share markets of Shanghai and Shenzhen exchanges during the pre- and post-event periods. A CBP-GARCH model is employed in our empirical analysis. The empirical results exhibit the evidence of bidirectional normal information transmissions between 'A' and 'B' share markets of both exchanges. However, abnormal information transmissions are unidirectional, flowing from 'B' share market to 'A' share market only. Our results are consistent with the information transfer hypothesis (Chiu and Kwok, 1998). Moreover, information transmissions mechanism is affected by the removal of investing restriction, thus the two markets are more integrated gradually.
