Growth of Digital Infrastructure of China and USA: Application of Intelligent Grey Forecasting Model

Mobile cellular telephone subscriptions and secure internet servers play an important role in the digital infrastructure of the country, and their growth projections hold useful information for planners and policymakers. The current study makes a pioneering attempt to forecast the growth in mobile cellular subscriptions and secure internet servers in the United States of America and China using an intelligent and flexible time-series grey model called EGM (1,1, α, θ). Secure internet servers in the US and China are projected to grow exponentially, while mobile cellular subscriptions for both countries showed linear growth. The error analysis done through the mean absolute percentage error revealed some interesting results related to secure Internet servers. The results provide useful insights for proper planning of the digital infrastructure of the two digital powerhouses.
