This paper investigates the return transmission between four Asian stock markets in Japan, China, Korea, and Taiwan. Specifically, applying a vector autoregression (VAR) model, this study derives the following interesting findings and interpretations. First, our results reveal that (1) rapid cross-country and autoregressive return transmission between the four Asian stock markets recently decreased, and (2) recently, the effects from the Japanese stock market to the other three Asian stock markets became weaker. Furthermore, our results clarify that (3) the return transmission effect from the Chinese stock market to the other three Asian stock markets is generally weak, also meaning that the Chinese stock market evolves autonomously.
