The invention discloses a carbon market transaction behavior modeling method integrating real participants and computer agents, and belongs to the technical field of power systems and automation thereof. By the carbon market transaction behavior modeling method, according to driving variables and decision variables of the participants in the bilateral concentrated carbon transaction process, a decision probability model for the computer agents is established; then hybrid simulation is performed in the coexistence of the computer agents and the real participants, and on the basis of statistical calculation of a large number of samples, the decision model for the computer agents is updated, therefore, multi-round iterative simulation is performed; through verification of the convergence of a decision model for the participants in the multi-round simulation process, whether the simulation is terminated is judged, and the converged decision model is used for substituting decision behaviors of a group of the real participants. By the carbon market transaction behavior modeling method, sensitivity analysis on key carbon market parameters can be effectively supported, and a sand table deduction tool is provided for the carbon market participants; the carbon market transaction behavior modeling method can be popularized in other bilateral market simulation analysis.
