With the increasing dependence on the international financial market as an economic system, China's main board market, which can be regarded as a barometer of China's economy, also shows its relevance to the international stock market. On August 25, 2065438+0518, the stock market crash in China, the United States and Japan in five trading days pushed this issue to the platform's attention again.

This issue mainly compares the stock index data of China Shanghai Composite Index and Dow Jones Industrial Average from 2005-20 15- 10, and then determines the general law of the influence of American stock market on China A shares. Through the simple understanding and empirical test of the linkage model of economists at home and abroad, the correctness of the general law is proved according to the analysis results. The main conclusions are as follows:

First, the American stock market has a great influence on the China stock market. Although the economic environment of developed countries started late, the development model has matured, the linkage among developed countries is strong, and China's economic market is still in an imperfect state. Relatively speaking, it should be more influential and must be accompanied by China's macro-control policies;

Second, the influence of Chinese and American stock markets is being influenced by the single American stock market on China stock market and stock market. This reverse effect is still in its infancy, but in the rapid growth of China's economy, China will have more and more influence on the United States.
