英文摘要：

The test was developed to analyze inter-market correlations among the main industries in China＇s stock market and three international stock markets, including Hong Kong, U.S. and Japan. The test results indicate three main conclusions. First, the international correlations of the industries are on the increase generally, while the correlation level is fairly low. Second, the gradual rise of correlation diversity among different industries implies that international economic and financial factors have different impacts on China＇s industries. Third, the test shows that there are some differences in international correlation growth rate among different industries. The international correlations of financials, basic materials, etc. have higher increasing rates relatively.
