将首次提出了综合考虑能源调控政策与市场供需的动力煤现货价格预测模型。首先基于煤炭价格形成机制的分析确定政策因素以及市场供需要素对煤炭价格的影响逻辑及其差异性并构建动力煤价格影响要素指标集；然后根据两类要素的影响逻辑的差异设计二阶段价格预测的深度学习模型这句话翻译成学术英文

"We proposed a comprehensive model for predicting the spot prices of thermal coal by considering both energy regulation policies and market supply and demand dynamics. Firstly, based on the analysis of the coal price formation mechanism, we identified the impact logic and differences of policy factors and market supply and demand factors on coal prices, and constructed an index set of thermal coal price influencing factors. Secondly, we designed a two-stage deep learning model for price prediction based on the differences in the impact logic of the two types of factors."
