Based on the Mix-operation and related theories, we provide (i) detailed analysis on the history of operation patterns of international financial industry and coming trend; (ii) introduction on the development of China’s financial industry in the real world. In view of the background, external scheme, institutional structure, and supervision system, we compare modes of operation among American’s Financial Holding Company, which is most adopted internationally, German’s Universal Bank, and Taiwan’s Financial Holding Company. By case studies, we suggest that the practical choice of China’s mix-operational financial industry would be the mode of American’s Financial Holding Company. Further, on the condition of China’s current situation of financial industry, we contribute our suggestions on the construction and progress of China’s Financial Holding Company, especially on the selection of main entity, ways of construction, choices of construction channel, the establishment of internal control mechanism and supervision system.
