The final effect of cross-cultural management of enterprise will be directly affected by the awareness of cultural differences and the corresponding measures. The origin of cultural dimensions theory and cultural intelligence theory is different; the focus of research is different either. But in the aspect of "cultural sensitivity", both theories are interlinked; in proper handling the cultural conflict, the roles of the two theories are complementary; and in the understanding of culture itself, the "dynamic" and "static" views are provided. With their own characteristics, cultural dimensions theory and cultural intelligence theory complemented each other. And they contribute to the normal "dialogue" between different cultures, different enterprises and different people. The combination of two theories helps enterprises to achieve a successful cross-cultural management.
