Industrial alternative electric quantity prediction method and system based on index screening and air temperature correction

The invention relates to an industrial alternative electric quantity prediction method and system based on index screening and air temperature correction. The method comprises the following steps: acquiring an industry demand variable and air temperature data; and inputting the industry demand variable and the air temperature data into a pre-constructed industrial alternative electric quantity prediction model to obtain a corresponding final prediction value of the industrial alternative electric quantity, wherein the industrial alternative electric quantity prediction model is constructed by determining the alternative electric quantity based on the combination of the industry demand and the economic prediction on the electricity consumption demand and revising the alternative electric quantity by utilizing the influence of the air temperature, so that the air temperature and the economic index are reasonably arranged in the same prediction model, and the prediction accuracy is improved. 本发明涉及一种基于指标筛选与气温校正的工
