Chinese government has been applying premium leasehold system which takes land use fee at a time since 1990. But because of fatal problems that premium leasehold system has caused, Chinese government re-started new experiment of land use system to supplement premium leasehold system’s errors since 1999. This new system is annual land leaseing system. This paper analyzed 3 cases of China: Shenzhen Special Economic District,Shanghai Pudong new district, Suzhou Industrial Park. From this case study, I intended to draw important insights to be applied in N. Korea’s special economic zones, which have been influenced directly from China’s land reform experiences. For this case study, I drew public land leasing system’s practice principles, or ‘land principles’. After case study, I found that the Pudong case showed most important insights. First of all, Pudong case expanded applying range to the extent of extra site, housing site belonged to important industry and guarantee-housing site. Next, when new special economic district is constructed, government land banking organization take a charge for the infrastructure construction and financing. By the way, if government doesn’t have sufficient ability,then ‘government drive-market oriented method’ can be applied. Finally,Pudong case tried elementary step to implement ‘tax-shift’ principle, where urban land tax is exempted from annual land rent. Shenzhen case showed important insights both on the transfer to annual land leaseing system, and on the evaluation of annul land rent. Suzhou case showed a important insight on the proper evaluation period of annul land rent.
