Fig. 7: The urban land maturation and efficiency enhancement process can meet urban economic growth demands before 2035.

Based on the perspective of different urban scales, SSPs is used to predict the land use efficiency of various ages. The sum of land use efficiency is compared with the 5% economic growth rate to determine whether urban land maturation and efficiency enhancement process can meet the needs of future economic growth. Blue represents that urban land maturation and efficiency enhancement process can meet the needs of economic growth, while pink represents that it does not meet the needs.
