Carbon emission quota distribution method in port industry

The invention discloses a port industry carbon emission quota allocation method, which comprises the steps of combining a TOPSIS model with an entropy weight method, and establishing a TOPSIS model-entropy weight method-based carbon quota allocation comprehensive evaluation model; the method comprises the following specific operation steps: determining evaluation objects and the number thereof; determining evaluation indexes and the number thereof, and associating the evaluation indexes with the evaluation objects to form a judgment matrix; standardization processing: performing dimensionless processing on the judgment matrix according to the evaluation indexes to obtain the judgment matrix; and determining an optimal scheme. According to the method, the quota distribution efficiency and accuracy of the historical strength method, the datum line method based on carbon strength sorting and the mixed distribution method based on the equipment energy consumption limit value are evaluated through empirical analys
