Infrastructure is the general term for basic physical systems of a business, region, or nation; for instance, transportation systems, communication networks, sewage, water, and electric systems are examples of infrastructure. These systems tend to be capital intensive (capex) and high-cost investments and are vital to a country’s functioning, economic development, and prosperity. Projects related to infrastructure improvements may be funded publicly, privately, or through public-private partnerships. In economic terms infrastructure often involves the production of public goods. It is very typical to see public financing, control, supervision, or regulation of infrastructure either wholly or to a certain extent.
