1, export enterprises that are beneficial to China can have greater competitive advantages and export profit margins will be greater;

2. It is beneficial to increase the sales volume of domestic enterprises' products, because the prices of imported products of the same type will be higher;

Second, about the disadvantages of currency depreciation:

1, which is not conducive to the development of imported enterprises. The price of imported raw materials has risen due to the depreciation of RMB, and the cost has increased;

On the essence of money;

1. currency is essentially a contract between owners about exchanging rights, and different forms of currency are essentially unified. In the past, due to people's unclear understanding of the essence of money, money was mistakenly divided into different types from different angles, such as: debt currency and non-debt currency according to the commodity value of money, convertible currency and non-convertible currency according to whether the exchange ratio of precious metals was agreed.

2. Formally, according to the commodity value of money, it can be divided into physical money and formal money. Physical currency itself is a special commodity, including value, such as sheep and precious metals. Formal currency itself has no value, its value is agreed by contract, only the contract value. The two forms are different, but they are essentially unified, that is, they are both agreed as exchange media and have contractual value. The purchasing power of money depends on the contract value of money, but the purchasing power of physical money will also be affected by its own commodity value. Usually, the commodity value of physical currency is less than its contract value as currency.

3. In high school textbooks, the essence of money is interpreted as universal equivalent. This definition only starts from the function, but actually does not explain the essence of money, nor can it answer the inherent logical question, that is, why money can act as a universal equivalent.
