These structural differences produce contrasting stracies for manageming urban growt, funding infrastructure, and balancing competig regional interests.

Federal Goverments and Urbanization

In federal countries such as the United States, India, Germany, Canada, and Australia, urban policy and infrastructure investment are largely decentralized. State or provincial goverments hold primary autority oler land use, zoning, transportation planning, public housing, and local public services.

However, decentralization also creates important difficies. Wealthier states can levy higer taxes and atrakte private investment, building stateof-theart transit systems and forwardable housing. Poorer states, limined by weaker economies, straggle to maintain basic roads, water systems, and schools. The U.S. Goverment Accountability Office has documented that infrastructure spending per capita varies widely across states, with rural and low-incomes fallinfurther behind.

Koordination Challenges in Federal Systems

Another hallmark of federalismus is the need for intergovermental coordination. Major infrastructure projects, such as high- speed rail or interstate highways, of ten cross state hranis and require agreements on funding, standards, and timelines.

Unitary Goverments and Urbanization

In unitary states such as the United Kingdom, France, Japan, and South Korea, the central goverment holds ultimáte autority over urban policy and infrastructure investment. Local goverments operate under destated pows and must compy with with nationale law, nordards, and planning guideines.
