我们使用重心模型和GIS软件，测算了1997年至2009年中国能源生产和消费中心的变化（位置、移动、距离和比率），从而揭示了供需关系的地区差异。研究发现，在研究期间，原煤消费、原油生产和消费、电力生产和消费的重心向西南方向移动，原煤和天然气生产的重心向西北方向移动，天然气消费的重心向东南方向移动。天然气的移动距离最大，其次是原油，但原煤和电力的移动距离较小，表明其供需模式在研究期间变化不大。原煤、原油、天然气供需缺口较大，并有扩大趋势。生产中心位于消费中心的西北部，表明中国的能源生产集中在西北部，而消费集中在东南部。这种格局是由中国能源资源分布和能源发展战略决定的。为缩小供需之间的差距提出了建议。
Using a center of gravity model and GIS software, we measured how China's energy production and consumption centers changed (positions, movements, distances, and rates) from 1997 to 2009, thereby revealing regional differences in the relationship between supply and demand. We found that the centers of gravity for raw coal consumption, crude oil production and consumption, and electricity production and consumption moved southwest during the study period, whereas those of raw coal and natural gas production moved northwest and that of natural gas consumption moved southeast. The distances moved were largest for natural gas, followed by crude oil, but the distances were small for raw coal and electricity, indicating that their supply and demand pattern changed little during the study period. The gaps between supply and demand for raw coal, crude oil, and natural gas were large, and tended to increase. The production centers were northwest of the consumption centers, indicating that China's energy production is concentrated in the northwest, whereas consumption was concentrated in the southeast. This pattern resulted from the distribution of China's energy resource reserves and its energy development strategies. Recommendations are provided to reduce the gap between supply and demand.
