The study of development control of foreign countries says that planning system, regulation system, review and permission process are useful for performing land use control effectively. The U.S. development control system has detail specific regulations for each land use, while Germany has B-plan (detailed district plan) and British has various review and permission processes in their development controls. On the one hand, Korea has actually the system mixing the three, it seems to have a zonning system though. The characteristic of Korean development control system gives confusion to officials and causes disorder in its development control. However, Korean development control system will expect to go to the planning system or the review and permission process, due to changing the circumstances in planning and improving the requirements of deregulation of land use system. Thus, it is very important to readjust the planning system and to improve the review and permission process in Korea. The opinions of experts about the time to transform into that kind of controlling development system are different. However, the time may be expected when the development demand decreases and the increase rate of population declines.
