摘　　要：电力资源在中国能源建设及能源发展方式转变中处于中心地位,全面降低电力强度是实现资源、经济、环境可持续发展的关键所在。研究中国电力强度重心迁移路径以及区域差异可以厘清电力强度分布状况,对实现上述目标具有现实意义。本文运用重心理论研究了中国1985年~2014年电力强度重心迁移路径,进而采用泰尔指数计算并分解了区域电力强度非均衡程度。研究结果表明:1985年~2014年,电力强度重心总体上呈现出持续向西迁移的态势。期间,1985年~1993年、2003年~2014年主要呈现为向西北方向移动,1993年~2003年则表现为向西南方向移动的特征。1985年~2000年,区域间及区域内部差异对于重心迁移的贡献率各占50%;2000年~2014年,重心演变推力主要来源于区域内部差异,贡献率均值为54.49%,内部差异则受西北、西南、华北地区影响最大。Power resource is at the center of China's energy construction andenergy development mode,meanwhile,at the same time,how to reduce the powerintensity is the key to sustainable development of Chinese,economy.Therefore,the study on the migration path of power consumption intensity gravitycenter and the regional difference can clarify the situation of China's powerintensity at present.By using the theory of gravity,the author studied themigration path of electricity intensity in China between1985-2014,and thencalculated the disequilibrium degree of China's power intensity by adoptingTheil index.The results showed that in the period of1985-2014,electric powerintensity in China takes on a tendency of continuing to west migration.During the years of1985-1993and2003-2014,the orientation of migration isnorthwest,but the orientation of migration is southwest in the year of1993-2003.In1985-2000the contribution of the power intensity between thedifferent regions and internal differences to the movement of power consumptionintensity gravity center are50%.During the period of2000-2014,the averageratio of contribution from internal difference is54.49%,northwest,southwest and north China account for the internal difference.
