The development of price theory as early as the 7th century BC, China recorded the management of the economic thought of the “tube” book, there is a discussion on the change of market price: “the collection is heavy, the hair is light”, “the people are lighter, the people are less than”; Gold is heavy and light,” “the valley is heavy and everything is light, the valley is light and everything is heavy”, “the currency is heavy and everything is light, the coin is light and everything is heavy”. In the 6th century B.C., Fan Wei put forward the “drought boat, water is a car”, advocated that in the society is not in urgent need of a certain commodity pre-storage, waiting for the time to sell at a high price, indicating that Fan Wei has understood the relationship between supply and demand and price, the use of price changes for profit.
