This article employs a hybrid model that combines DEMATEL and ANP to explore the determinants of Japanese MNEs invest in Taiwan. In addition to the four motives (namely Market Seeking, Efficiency Seeking, Resource Seeking, and Strategic asset Seeking) Dunning (1993) classified, this article proposes a new Network Seeking motive to catch the Taiwan Japan historical ties. Research results show that Efficiency Seeking is the most strength of influence with other motive. Besides, Network Seeking dispatches the strongest influence on the other motives. These results highlight the important roles of Efficiency Seeking and Network Seeking play in the Japanese MNEs investment in Taiwan. Especially, most Japanese MNEs regard Taiwan as a “step stone”, they will expand to invest in other countries in the future instead of to invest in Taiwan permanently.
