The most intuitive is determined by the market. Simply put, it is the relationship between supply and demand. (1) Relationship between supply and demand: if supply exceeds demand, the price will decrease; If the supply exceeds the demand, the price will go up. (2) Production cost: The lower the production cost, the lower the price; The higher the production cost, the higher the price. (3) Virtual economy: (Virtual economy refers to the economic activities related to the circular movement of virtual capital, which mainly rely on the financial system. Simply put, it is directly related to the activities of Qian Shengqian. For example, international crude oil fell from 100 to $40 within100 days. One of the reasons is that oil demand has decreased due to the international financial crisis. The main reason is the withdrawal of "copying funds". (4) Currency issuance and circulation: With more currency, commodity prices will certainly go up (inflation). For example, the international crude oil price has been standing above $50 recently, mainly because the market expects the US Federal Reserve to print more dollars. (5) Market monopoly: Enterprises or other organizations with market monopoly have "commodity pricing power". For example: Microsoft Windows operating system software. As for what affects the relationship between supply and demand, this problem is very complicated. It can be said that it involves all aspects of economics, and a short article cannot explain it clearly. Personally, I suggest that if you don't understand something, you can read Principles of Economics written by Man Kun. Remember, this is written by Man Kun. The contents in his book are easy to understand and absolutely suitable for anyone.
