5. Hello,
money serves as the medium of commodity exchange. In the process of commodity exchange, the seller converts the commodity into money, and then uses money to buy the commodity. Here, money plays the role of medium of exchange and performs the function of means of circulation. The function of currency as a measure of value is the premise of its function as a means of circulation, and the function of currency as a means of circulation is the further development of the function of value measure< Before the emergence of money, commodity exchange was direct barter. After the emergence of money, it plays a medium role in the commodity exchange relationship. Commodity exchange with money as the medium is commodity circulation, which is composed of two processes: commodity to currency (w-g) and currency to commodity (G-W). The stage of w-g selling is the first form change of commodity. This stage is very important and difficult to realize. Because if the commodity can not be sold and the original commodity form can not be converted into currency form, the use value and value of the commodity can not be realized, and the owner of the commodity may go bankrupt. G-W is the buying stage, which is the second form change of goods. Since money is the general equivalent of all goods, if there are enough goods, money can buy goods. This stage is relatively easy to achieve. As a medium of exchange, currency functions as a means of circulation in commodity circulation, breaking the restrictions of direct barter and local exchange, expanding the variety, quantity and geographical scope of commodity exchange, thus promoting the development of commodity exchange and commodity proction
money circulation
as a means of circulation, money is constantly used as a means of purchase in the process of commodity circulation to realize the price of goods. After a certain circulation process, commodities must leave the circulation field and finally enter the consumption field. However, as a means of circulation, money has always remained in the field of circulation, constantly transferred from the buyer to the seller. This constant change of hands forms the currency circulation. Money circulation is based on commodity circulation, which is the manifestation of commodity circulation. As a means of circulation, money needs to have a certain quantity corresponding to the quantity of commodities. In a certain period, the amount of money needed for commodity circulation is determined by the total price of goods to be sold and the average speed of money circulation (see the law of money circulation). The amount of money needed in commodity circulation is directly proportional to the total price of commodity: if the total price of commodity is large, the amount of money needed in circulation will be more; If the total price of a commodity is small, the amount of money needed in circulation will be small. The amount of money needed in circulation is inversely proportional to the speed of money circulation: if the speed of money circulation is fast, the amount of money needed in circulation will be less; If the speed of money circulation is slow, more money is needed in circulation. In a certain period of time, the amount of money needed for commodity circulation is equal to the total price of all commodities divided by the average speed of currency circulation of the same unit, which can be expressed by the following formula:
the form of money as a means of circulation
the money as a means of circulation initially appears in the shape of gold or silver. Because the fineness and weight of metal strips are different, it is very inconvenient to check the fineness and weigh the weight every time. With the development of commodity exchange, metal strips were replaced by coins with certain fineness, weight and shape. The emergence of coinage enables money to better play its function as a means of circulation. Coins will be constantly worn out in circulation, the name of the currency and its actual weight graally separated from each other and become worthless coins. As a measure of value, money can be conceptual money, but it must be of sufficient value; As a means of circulation, money must be real money, but it can be undervalued. This is because the function of currency as a means of circulation is only a transient medium. Coins with insufficient value, or even currency symbols with no value at all, can also be used to replace metal currency circulation. Coinage made of base metals, such as copper, is a kind of worthless coinage. The banknotes issued by the state and forced to circulate are purely value symbols. The paper currency has no value, it just takes the place of metal currency to carry out the function of circulation means. No matter how much paper money is issued, it can only represent the amount of metal money needed in commodity circulation. If the issue of paper money exceeds the amount of metal money needed in commodity circulation, the amount of gold represented by each unit of paper money will decrease, and the commodity price will rise accordingly
because money acts as a means of circulation, it breaks the time limit for the purchase and sale of goods. A commodity owner may not buy goods immediately after selling them; It also breaks the restrictions on buying and selling space. After selling goods, a commodity owner can buy other goods on the spot or buy any other goods in other places. In this way, there may be a disconnect between buying and selling. Some commodity owners only sell but not buy, while others can't sell. Therefore, money as a means of circulation has bred the possibility of causing economic crisis.

6. The problem is actually very simple. First of all, do you know what circulation is? The reason why money has the function of circulation means is that money is determined as a general equivalent
all items need to be converted into currency and then into other items through currency. The function of circulation means of natural currency can be reflected

7. The function of circulation means is that money is the medium of commodity exchange, that is, the function of purchasing means. Generally speaking, it's one-off payment and one-off delivery. Therefore, from the perspective of value movement, when money performs the function of circulation means, the movement of value is bidirectional at the same time. That is, the seller transfers the use value while getting the value, and the buyer obtains the use value while transferring the value. The electricity, water, taxes and wages you asked are all means of payment. The means of payment appeared with the appearance of the sale of goods on credit. In credit, money is used to pay debts. Another popular explanation to you is: you can't pay once you use a ton of electricity or water. They are all paid at the end of the month. It's the same with paying wages and taxes. You can't let your boss pay you a day's wages after you work. You can pay taxes once you get a day's wages, which is also paid once a month. Here are used to buy and sell on credit. Naturally, it is the means of payment.
