摘要
煤炭是我国重要的基础能源,环渤海动力煤价格是全国煤炭价格变动的风向标。通过分析影响环渤海动力煤价格变动的指标,构建出环渤海动力煤现货价格多元线性回归预测模型,并对下阶段进一步完善模型提出建议。
Coal is an important basic energy source in China,and the price of thermal coal in the Bohai Rim is a weather vane for changes in coal prices across the country. By analyzing the indicators that affect the price changes of thermal coal in the Bohai Rim,a multiple linear regression prediction model for the spot price of thermal coal in the Bohai Rim is constructed,and suggestions are made on how to continue to improve the model in the next stage.
