The concept of ownership in economic system of socialist states is different from the concept of those of capitalist state’s. This is not a classification based on private person in capitalist-economy-system, but a classification based on the actual ownership type in socialist’s. Due to these differences in such criteria, the type of ownership is divided into the form of state ownership, cooperative group ownership, and personal (private) ownership. Unlike our ownership-system, the type of ownership of socialist states are characterized by the discipline of ownership from three types. There is no difference with Vietnam in ownership system. Based on the private ownership of Civil Code of 2005 in Vietnam, they were regulated upon the land use right. According to Civil Code of 2006, the scope of personal(Private) ownership was limited to the rights to use the land. However, according to the Civil Code of 2015, the scope of private land use right is as follows: the right to adjacent immovable property, the Usutruct, and surface rights. From this fact can man recognizen that, the usufruct und surface right ist more wider than the scope of land use rights in North Korea's Civil Code of 2007. In other words, it seems that Vietnam maintains a socialist economic system, at the same time satisfy personal own desires by expansion of private ownership. The content is as follows; By the import of kapitalist economy in the private sector, at first, it maintains a socialist ownership form in the joint ownership sector. It seems to accept the kapitalist economy system by expanding the use of it, while maintaining the socialist economic system. Therefore, we can deduce the changes in the socioeconomic situation of North Korea, we will also have to prepare our plan.
