The study looked at how well urban land development and population growth match up in Qinghai Province, China. By studying two cities closely, the researchers found that the process of turning land into urban areas was slower than the rate at which people were moving into these areas. They used a special method to measure this mismatch and suggested that it's really important for these two things to grow together more evenly in the region. This means that as more people come to live in the city, it's crucial that there's enough urban space for them to live and work in too. The study found that right now, there's some catching up to do so that the land development and population growth can work well together in Qinghai Province.
