Moreover, past studies also improved the great impact from America to other international markets or even Asia markets. This study empirically tests the direction and scale of the correlation in stock returns of Taiwan and Main America, European, Asian stock Market. We explore the volatility driven correlation in stock returns of Taiwan stock market and main stock markets of America, Europe and Asia by regressing the generalized logit transformed correlation on the log transformed volatilities to show the volatilities of these stock returns how to affect the relationship of correlation. The result shows that except some stock returns there are significantly positive volatility driven correlation between Taiwan stock return and some stock returns of other stock markets. Besides, we found the volatility of American stock returns has the highest impacts on the correlation between Taiwan and American stock markets in terms of the absolute value of the estimated coefficients in ARMA model.
