This paper emphasizes that a country should emphasize the dual financial system at the same time, i.e., emphasizing the banking financial intermediation and equity financial intermediation. These two financial intermediations are complementary during the financial crisis. The factors to achieve successful banking and equity financial intermediations is to have good government governance as well as emphasizing small shareholder protection and debt holder protection. In the banking financial intermediation, we need big and small banks. This report suggests five criteria to evaluate a successful big bank. With respect to the small bank, it needs to find its niche. Turning to the case of equity market, this paper suggests to have market feature, stock exchange feature and country nature.
