A Game Model and Simulation Analysis of Emission Reduction Problem Between Enterprises and Third-Party Verifiers

Under the government subsidy mechanism, this paper investigates the behavioral choices and evolutionary dynamics of carbon emission reduction enterprises and third-party verification agencies using an evolutionary game model. The model is also simulated and analyzed by using MATLAB software. The results show that the final behavioral choice of carbon emission reduction enterprises is to reduce carbon emissions under different amounts of government subsidies, fines for excess carbon emissions and fines for negligence, the probability of unscheduled government spot checks, and the price of carbon trading market. The decision of the third-party verification agency is determined by the amount of government financial support. Therefore, the government should formulate appropriate subsidy policies and reward and punishment mechanisms to promote the environmental monitoring behavior of third-party verification agencies, in order to achieve the purpose of reducing social carbon emissions and protecting the environment.
