Abstract: The provision of economic benefits and capital services are two basic functions for infrastructure capital to play a role in the social and economic system, which are measured by the net capital stock in the existing literature. Therefore, this paper also measures capital services that describe the productive function of infrastructure within the same framework. This paper divides infrastructure into economic infrastructure and social infrastructure, simulates their service age-efficiency function, service age-price function and service age-depreciation rate function respectively, calculates the net capital stock and capital services of infrastructure in China from 1978 to 2020, compiles the capital account of infrastructure, and describes the whole process of capital movement of infrastructure (investment-accumulation-service). The empirical results show that the net capital stock can better reflect the wealth of China's infrastructure, and infrastructure capital services are an important force to promote economic development.
