煤炭价格波动受多种因素影响。以秦皇岛港动力煤现货价格为例，利用灰色关联分析法，建立动力煤价格与港口库存、进口煤价格、BJ 指数、海运费、全国重点电厂存煤可用天数关联分析模型，识别动力煤价格主要关联因素，同时利用多元回归模型对动力煤现货价格进行预测。

Fluctuations in the price of coal is affected by many factors. Qinhuangdao Port coal spot prices,for example,by use of gray relational analysis,the author establishes analysis model between thermal coal price and port stocks,the price of imported coal,BJ index,sea freight,the number of days available of stored coal in the national focus of power plants to identiG fy mainly associated factors on the thermal coal prices,while taking advantage of the multiple reG gression model to predict the spot price of thermal coal.
