Using this result compares with Engle&Granger (1987) causality and Johansen (1988) cointegration so that could understand the situation between of these two markets. If there are any restrictions between them. As a consequence of this empinical study, it seems market integration. Compared with the parity bounds model, the cointegration approach would over-elvaluated the result of testing market integration. The parity bounds model proposed more information concerning market integration.10473438 bytesapplication/pdf共整合模型等值臨界模型空間市場整合CointegrationParity boundsSpatial integrationjournal article10.6181/AGEC.200206_(28).0003http://ntur.lib.ntu.edu.tw/bitstream/246246/282201/1/0028_200206_3.pdf
