Secondly, the law of diminishing marginal cost of network economy. Information network operation costs mainly include initial network construction and daily maintenance costs, costs that may occur in the process of information transmission, and Costs of information recovery and information processing. In addition to the cost of collecting and processing information related to the number of subscribers to the network, the long-term one-time costs associated with the construction and operation of the network platform will increase as a result of the need to build and operate the platform. investment, the marginal cost of information network operation tends to be zero, and the correlation between investment costs and the number of new users accessing the network and the frequency of network usage is almost zero. to zero. "Thus, as the number of users accessing the network increases, the average and marginal cost decreases." Thus, in the network economy, marginal revenues gradually increase due to the decrease in marginal costs.
