As a result of more and more serious energy risks, the study of national energy security zoning is not only the basic requirement of energy risk management but also the new demand of economic development for the energy industry. Firstly, this paper analyzes the basic situation of energy resources and production and consumption of pri-mary energy from 1996 to 2005 in China. Secondly, this paper founds an Energy Security Index System formed by six indices including the percentage of energy reserves, interlocal dependent degree, energy elasticity coeff icient and so on. It subsequently calculates the weight of these indices with the factor analysis rating method. Lastly, the paper evaluates and zones the abilities of energy security of 30 provinces in China with the grey cluster method. According to their security, the 30 provinces are classif ied into three different levels: high, medium, and low levels. The regions at low energy security level include Beijing, Shanghai, Zhejiang, Fujian, Guangdong, Guangxi and Hainan. They are mainly littoral and short of primary energy production while mostly dependent on other provinces. Those at medium energy security level include 15 provinces (cities or districts), such as Liaoning, Tianjin, Hebei, Shandong, Henan, Hunan and so on. These provinces are in the northeast, north, east of and central China. Those at high energy secu-rity level contain Shanxi, Inner Mongolia, Heilongjiang, Jilin, Chongqing, Sichuan, Shaanxi, Xinjiang. These prov-inces are the main primary energy production bases.
