Abstract:Through sampling 1354 Listed Corporations in Shanghai Stock Exchange and Shenzhen Stock Exchange, this paper analyzes the correlation between the rising rate of stock price and their financial index as well as their change rate by using linear regression model. The result shows that stock price rate and earnings per share has the significant positive correlation, but a significant negative correlation with the long-term debt ratio. In short term, the index which affects the stock price is the earnings per share, but, in long term, it is mainly the long-term debt ratio, and the longer the time is, the greater the influence will become. However, the change rate of other financial indexes has little impact on the stock price.
