Abstract: With the development of industry differentiation in Internet application platforms, suppliers can more accurately enter into different consumer community, which leads to many new changes in the consumption structure. From the perspective of the docking of consumption Internet and industrial Internet, it is of great significance to explore the economic theory of new consumption.Under the condition of consumption Internet, consumers enter the market in different ways from the past, which not only changes the way of demand expression and the information search method of consumer goods, but also changes the decision-making mode of consumer purchases. Consumers participate in the production process through the Internet application platform, and their demand of product is more clear, which is not only conducive to improving the information symmetry between demand and supply, but also conducive to innovation in product and production technology, and to the formation of an ecological development model in which consumers and producers achieve value co-creation, and the benign interaction between consumption and production. The further connection between consumer Internet and industrial Internet will certainly promote the development of digital resources and value co-creation, the transformation and upgrading of industrial structure, benefiting the development of China's economic dual-cycle pattern.
