Features of infrastructure:
(1) Priority and foundation. Public services provided by infrastructure are essential for the production of all goods and services. Without these public services, other goods and services (mainly direct production and business activities) will be difficult to produce or provide.
(2) Non-tradable. Most services provided by infrastructure are difficult to import through trade. A country can finance and introduce technology and equipment from abroad, but it is unthinkable to directly introduce airports, highways and water plants from abroad as a whole.
(3) Integral inseparability. Usually, only when the infrastructure reaches a certain scale can it provide services or provide services effectively. Small-scale investment can not play a role in roads, airports, ports, telecommunications and water plants. For example, the power station dam should not be built only in the middle of the river, the airport runway should not be unfinished, and the light rail connecting the two cities should not be built only in half.
(4) Quasi-public products. Some infrastructure services are relatively non-competitive and non-exclusive, similar to public goods.
