By using Northeast China as example, this study measured the characteristics of the land use transition of underdeveloped areas (UAs) of China and explored the underlying transition mechanism. This study found that, the main characteristics of the land use transition of Northeast China during the last two decades (1995–2015) were continuous expansion of cropland, accelerated growth of construction land, and continuous reduction of woodland and grassland, as well as unused land. Policies dominate the process of land use transition of the UAs of China. The land use transition of UAs of China is a result of interaction and coupling between socio-ecological feedback under the guidance of policies and socio-economic change under the influence of policies. The former determines the direction of regional land use transition while the latter determines the intensity of this transition. During the process of land use transition, the sustainable use of land of the UAs of China faces several severe issues: inefficient use of urban construction land caused by unreasonable policy support, degradation of the ecological environment caused by irrational expansion of cropland, and both policy instability and policy conflicts. To resolve these issues, punishment and accountability of local governmental violations of land use should be strengthened. Furthermore, a land use information disclosure system and public supervision mechanism should be established by policy makers. The starting point of policy formulation should be shifted from quantity growth to quality improvement as well as from economic benefits to comprehensive benefits.
