Emission reduction technology layout method and device for key emission industry

The invention relates to the technical field of energy conservation and emission reduction, and provides an emission reduction technology layout method and device for key emission industries. The method comprises the following steps: analyzing the energy consumption of each variety involved in each key emission industry, and obtaining the carbon dioxide emission of each key emission industry in a target node year; determining the technical emission reduction cost of the key emission industry in the target node year, and determining the distributed power generation investment cost and the corresponding emission reduction of the target node year; the total emission reduction amount and the total emission reduction cost of the key emission industry in the year of the target node are obtained; and by taking the minimum value of the total emission reduction cost of the key emission industry in the target node year as a target, carrying out layout on the emission reduction technology of the key emission industry in
