The phenomenon of economic financialization in contemporary capitalist countries is generally consistent with the time of Internet production and application. The Internet provides a technical basis for the financialization of capital. It not only adjusts the proportional relationship between capital, but also protects the continuity of capital movements by expanding the scale of circulation in total social capital and reducing the scale of production. Relationships enable virtual capital to gain high profits through virtual space to increase the control and power of financial capital. The financialization of capital accumulation is manifested in such three aspects as financial function alienation, industrial capital financialization trend and wage financialization, which leads to the transformation of the surplus value of workers from production to the accumulation of capitalists and workers in the financial exploitation. Although it can enhance the continuity of capital movement, it can not solve the basic contradiction of capitalism.
