Emergence: Driven by the second industrial revolution, the capitalist economy began to undergo major changes. The trend of capitalist production socialization has intensified, which has promoted the intensification of competition among enterprises and the concentration of production and capital. A few enterprises adopting new technologies have crushed a large number of enterprises with backward technologies. When production and capital are concentrated to a certain extent, monopoly comes into being. A few large enterprises that have grown stronger in the competition have reached an agreement on output, product price and market scope, forming a monopoly organization. There are two main ways to produce monopoly organizations: first, enterprise competition, advanced enterprises crush and merge backward enterprises, so that production and capital are continuously concentrated, resulting in monopoly organizations; Second, emerging industrial sectors need to implement large-scale centralized production, or rely on the protection of economic systems such as patents to produce monopoly organizations.
The form of monopoly organization was first formed in the circulation field, resulting in cartel, syndicate and other forms of monopoly organization; Later, monopoly organizations such as trusts emerged in the production field. Monopoly organizations appeared in major capitalist countries in the late19th century. Monopoly is the essential feature of imperialism. With the widespread emergence of monopoly organizations, major capitalist countries entered the stage of imperialism at the end of 19 and the beginning of the 20th century.
