Carbon market emission price prediction method and system based on grey model

The invention belongs to the technical field of data processing, and particularly relates to a carbon market emission price prediction method and system based on a grey model, and the method comprises the steps: obtaining a historical price data sequence of a carbon transaction market in a region; calculating to obtain the optimal order of the fractional order operator mean difference GM (1, 1) model under the minimum average relative error by using the adaptive mutation particle swarm optimization algorithm of the optimal order, and substituting the optimal order into the model; constructing a grey theory GM (1, 1) model form, substituting data of the historical price data sequence, establishing a prediction formula, obtaining a solution of a whitening equation, and obtaining a periodic response function; and outputting carbon market emission price prediction data based on a grey theory GM (1, 1) model of the optimal solution. After an enterprise decision path in a carbon transaction market is analyzed, a ca
