The spatial interaction model

The spatial interaction model is a concept used to understand how and why people and goods move between different locations. It examines factors like distance, population size, and the attractiveness of places to predict the flow of movement. For example, it can help explain why people are more likely to travel to nearby stores rather than those far away. Essentially, it analyzes how location influences interactions, highlighting the importance of proximity and connectivity in shaping social and economic exchanges within a geographical area.
