With TGARCH model, this paper empirically examines the spillover effect of price and volatility among the two markets using sample of 18 dually-listed stocks' daily data from mainland and Hong Kong Stock Exchanges. We get the conclusion as follows: Return of half dually-listed A shares are in line with the Hong Kong market and the opposite influences are different due to different stocks; spillover effect exists among the two markets, the volatility of Hong Kong market is influenced by the mainland market more obviously than Hong Kong market to mainland market; information asymmetry is obvious among the two markets; good information has a leverage effect, and good information of A share market hasa more notable effect to Hong Kong market in volatility effect than Hong Kong to A share market.
