The main structure of this paper consists of two parts: theoretical analysis was mainly conducted in the first part, which including chapter 1 and 2, in this part the analysis was focusing on the connotation of liquidity, the supply and demand theory, the measuring methods, as well as micro-and macro-economic effects, and then proposed that the periodic reversal of liquidity was the concrete manifestation of the financial crisis; the second part, including the chapter 4,5,6 and 7, which cases analysis were made mainly in this part.
