There are four innovations in this paper: firstly, in order to focus our research on the development of matured stock market, we use the data in 2007 as our sample interval, which makes the results of the model more convincing. Secondly, taking the potential non-linear relationship among the various of indexes fully into account, we employ cointegration test instead of using the multiple variables linear regression method to study stock price index and macroeconomy.
