spatial interaction

Spatial interaction refers to the movement or flow of people, goods, information, or resources between different locations on the Earth's surface. It describes how places connect and communicate based on factors like distance, accessibility, and attractiveness. For example, people traveling to shop, goods shipped between cities, or online data exchanged across countries all illustrate spatial interaction. Understanding it helps explain patterns of economic activity, urban development, and transportation systems, illustrating how geographic proximity and other elements influence the way different places interact and depend on each other.
