Types of Infrastructure
1. Soft Infrastructure
Soft infrastructure refers to all the institutions that help maintain a healthy economy. These usually require extensive human capital and are service-oriented toward the population. Soft infrastructure includes all educational, health, financial, law and order, governmental systems (such as social security), and other institutions that are considered crucial to the well-being of an economy.
2. Hard Infrastructure
Hard infrastructure comprises all the physical systems that are crucial to running a modern, industrialized economy. It includes transport systems such as roads and highways and telecommunication services such as telephone lines and broadband systems.
3. Critical Infrastructure
Critical infrastructure makes up all the assets that are defined by the government as being crucial to the functioning of an economy. It includes assets used for shelter and heating, telecommunication, public health, agricultural facilities, etc. Examples of such assets: natural gas, drinking water, medicine.
Financing of Public Infrastructure
Public infrastructure is financed in a number of ways, including publicly (through taxes), privately (through private investments), and through public-private partnerships.
Public Infrastructure may be financed through taxes, tolls, or metered user fees. Since public infrastructure is open for use by the general public, the general public pays for the infrastructure facilities through taxes.
Public infrastructure tends to require high-cost investment projects, the returns on which are also extremely high. Sometimes, private companies choose to invest in a country’s infrastructure projects as part of their expansion initiatives.
For example, a power and energy company opts to build railways and pipelines in a country where it wants to refine petroleum. The investment benefits both the company and the domestic economy.
3. Public-Private Partnerships (PPPs)
Public-private partnerships (PPPs) are best described as a partnership or an arrangement between two or more private organizations and the public sector. A public-private partnership is the most popular means of financing large public sector projects. It helps to spread risks and makes the economy prosperous by bringing in investment opportunities, opening up employment opportunities, and increasing the standard of living.
