The Influence of Shanghai-Hong Kong Stock Connect on the Mainland China and Hong Kong Stock Markets

China has been intensively launching opening-up policies since November 2014. Among these policies, the Shanghai-Hong Kong Stock Connect offers international investors an approach to investing directly in Mainland China stock markets. At the same time, Mainland China capital can gain access to overseas markets via Hong Kong. This study investigates the influence of the policy by using the Vector Autoregressive and Generalized Autoregressive Conditional Heteroscedastic framework. The results show that the new policy has different impacts on the Shanghai, Shenzhen, and Hong Kong stock markets due to their distinct market features and policy restrictions. The three markets also transmit the policy effects to one another due to their close linkages. It not only indicates that Mainland China financial centers (Shanghai and Shenzhen) integrate with one of international financial centers (Hong Kong), but also symbolizes the gradually increasing strength of Chinese policy effects on global capital markets
