The study looked at how housing prices in different urban areas in China are connected to each other. They used a model to analyze the relationships between housing prices in three major urban regions. The researchers found that housing prices tend to cluster together in these urban areas. The way housing prices are connected varies between regions, with some areas having more complex connections than others. They also found that the effects of high housing prices in central cities can spread to surrounding areas. This information can help policymakers make decisions about how to manage housing prices in urban areas.
