摘要：

With the Chinese stock market integrity, it is available to compare the announcement effects of a company listed in different stock markets. Using a sample of Chinese corporate news announcements from the period January 2002 to December 2007, this paper finds that there are different announcement effects about returns, volatility of returns and volume of trade in Shanghai and Shenzhen stock market in the event window. The paper points that the market structural difference is a main reason that causes the different annoucement effects in Shanghai and Shenzhen stock market.
