Abstract: Geoborder theory is set up on the bases of geopolitics, geo-economics, geo-culture and geo-technologic, and geo-entity is the research object and core content of geoborder theory. The concept and content of geo-entity are brought up in this research, after the above bases are analyzed synthetically. Then the system of geo-entity types is set up, and geo-entity attributes is analysed, and geo-entity space relation types are explored. Overall, this research put one of the geoborder theory core content,and is the basis of geoborder theory.
