Its formation has promoted the economic growth of various countries and regions and the strengthening of international relations. First of all, it has promoted the vigorous development of social productive forces in all countries of the world. Secondly, it further promoted the development of western capitalism and objectively promoted the development and growth of the new social and economic structure in the eastern countries. Third, it has strengthened the social and economic relations among countries in the world, leading to the formation of the world economic system.

The development of the world market under the rule of capitalism has two functions: on the one hand, it internationalized the capitalist mode of production and exchange as an advanced mode of production at that time, broke the natural economy and closed-door state of backward countries and regions in the world, spread advanced science and technology and culture to the world, and promoted the development of world trade and productivity. From 1720 to 100 of 1820, the world trade volume increased by 1.74 times; From 1820 to 1870, an increase of 6.7 times; From 1820 to 1870, the world industrial production has increased nine times. On the other hand, the world market was formed in the colonial expansion and plunder of western countries, which not only made Asian, African and Latin American countries suffer the exploitation of unequal exchange, but also made them economic vassals of developed capitalist countries. The history of the formation of the capitalist world market is also a history in which industrial countries exploit agricultural countries and the West rules the East.
