Abstract: In Jiangsu Province, the lack of energy resources lays a foundation of the development pattern of the electricity power industry that is mainly in the form of import. In spatial distributon, the electric power industry is relatively centralized along Yangtse River, in Xuzhou area and in the consumeption center located in the South Jiangsu, forming a structure of “small” that slants to the right. The authors expound systematically the characteristic of the spatial structure of the electricity power industry in the form of “small” and its present problems，and analyse the mechanism of its forming. With the distribution of the energy resources and the economic development pattern in Jiangsu Prorince, the authors suggested to construct a new spatial structure of electricity power industry with “OZ” as its main framework, which is incorporated as:（1）to further upgrade the Riverside Belt of the electricity power industry in order to form the “/” part of the “OZ” structure；（2）to energetically push the development of inshore electricity power industry and to accelerate the rising of the Inshore Energy Axis in order to give prominence to the upside “－” part of the “OZ” structure；（3）to transmit natural gas from the west to the east, to promote the upgrade of the electricity power production in the south Jiangsu in order to reshape the downside “－” part of the “OZ” structure；（4）to strengthen the development of Xuzhou Energy Syntheses in order to expand the “O” part of the “OZ” structure.

Key words: electricity power industry, the spatial structure in the form of “small”, mechanism, the spatial structure in the form of “OZ”
