The development process was formed and developed in the development of human society to the stage of capitalism. It is the initial form of international economic relations and the international exchange of goods. As early as the 14th to 15th centuries, capitalism emerged in some countries along the Mediterranean coast, and international commodity exchanges were more frequent. From the 16th century to the mid-18th century, with the development of capitalism, the discovery of geography, the development of colonies, and the primitive accumulation of capital, the international commodity exchange has developed considerably, and the emergence of international division of labor has emerged. In the mid-18th century to the 1970s, developed countries in Europe and America completed the industrial revolution. With the establishment of capitalist production methods, the emergence of large-scale machinery industry, the demand for domestic production and market can not be met. Some advanced countries urgently need to go overseas to find sales markets, raw materials and sources of living materials. At this time, the great development of the transportation industry has promoted international economic exchanges. Therefore, the formation of advanced countries to sell industrial products to backward countries in large quantities; the natural economy of backward countries has gradually been broken, becoming the market for advanced countries to dump industrial products and the provision of raw materials, food, and labor bases. The division of labor and opposition between industry and agriculture within a country began to transform into an international division of labor and opposition between industrial countries based on advanced technology and agricultural countries based on natural conditions. Since countries and regions with different levels of economic development are involved in the scope of international division of labor, through the international commodity exchange, the economies of various countries have begun to build a whole, and the world economy has taken initial shape.
