The article explores how different groups like residents, property developers, and the government make decisions that affect the development of urban residential areas. By creating a model that simulates these interactions, the researchers found that residents choose where to live based on what they like, developers build where they can make the most money, and the government adjusts plans based on social and environmental factors. The study showed that in some areas, there is not enough redevelopment of old urban spaces, and that government policies can influence how cities grow and change over time.
