Abstract
This article use the smooth transition Generalized Autoregressive Conditional Heteroscedastic (GARCH) model to examine the impacts of direct cross-strait shipping on the dynamic structure of the stocks of shipping companies in Taiwan. We inferred the fact that the structural changes affect the volatility process for all stocks of shipping companies. In addition, we obtain the transition function for all related stock volatilities of shipping companies and find that their structural adjustment processes launch prior to the introduction of direct cross-strait shipping. Meanwhile, the estimated transition functions show that the stock return volatilities of shipping companies have U-shaped patterns of structural changes. This article also caught the corresponding calendar dates of structural change about volatility pattern.
