中文摘要：

居民生活能源的消费情况已成为促进经济社会发展战略的一个重要技术指标。在经典灰色模型的基础上结合均值算式进行优化，并以中国统计年鉴2015最近几年的人均消费情况为应用实例。预测结果表明，灰色模型预测是可行的，且优化的灰色模型比经典灰色模型预测的效果更好，预测精度更高，对未来短期预测提供了有效的参考价值。

英文摘要：

The living energy consumption of residents has become an important technical index to promote the economicand social development strategy.In this paper,the classical grey model is optimized in combination with the average value formula.The recent per capita consumption in China Statistical Yearbook2015is taken as the application instance.The predictionresult shows that the optimized gray model is feasible to forecast,and its prediction result and accuracy are better than those ofthe classical gray model.The grey model provides an effective reference value for the future short-term forecasting.
