International value or its transformation form is the basis of the formation of international market price. On the basis of domestic value, the international value of goods is formed through international competition of similar goods and services. The international value is determined by the international necessary labor time. In today's international market, the basis for the formation of international market prices is the international production price. International production price is the transformation form of international value, which depends on the sum of production cost and average profit of each country.

(2) Currency value and its exchange rate;

Price is the monetary expression of commodity value, and the change of monetary value directly affects the price movement. Therefore, the change of international market price is not only restricted by commodity value, but also influenced by the change of currency value and its exchange rate.

(3) Supply and demand in the international market;

The relationship between supply and demand in the international market refers to the comparative relationship between the total amount of goods provided to the international market by countries all over the world and the demand for it in the international market with the ability to pay. When this proportional relationship changes, the international market price also changes.

(4) International market competition;

There are three kinds of international market competition:

1, the competition between buyers often leads to the price increase in the international market;

2. The competition between sellers often leads to the decline of international market prices;

3. The influence of the competition between buyers and sellers on the international market price varies according to the market supply and demand situation and the strength comparison of two competitors.

(5) international monopoly;

The influence of monopoly on the international market price depends on the degree of their monopoly on the international market. The higher the degree of monopoly, the stronger its ability to control the international market price; The lower the degree of monopoly, the fiercer the competition, and the weaker the monopolist's ability to control the international market price.

(6) Government policies and measures:

With the intensification of international competition, governments all over the world have generally increased their intervention in economic activities. These interventions generally directly affect the formation and change of domestic market prices, and then affect the international market prices.
