Tripartite stakeholder decision optimization of aircraft leasing based on SD evolutionary game

Based on the evolutionary game theory and considering the new relationship between the leasing parties as parent-subsidiary companies, a tripartite evolutionary game model of the government, airlines and leasing companies was constructed, the system dynamics (SD) method was used to conduct dynamic simulation of strategies, and sensitivity analysis was conducted on key factors affecting evolutionary strategies. When the government enhances social benefits and actively regulates, the penalty imposed on leasing companies by airlines adopting an 'antagonistic' strategy increases, and so does the additional revenue of leasing companies, thereby accelerating the maturity of the aviation leasing market. The research results can provide the direction for the leasing market to accelerate its maturation under the new relationship, and also a theoretical basis for the government to formulate regulatory policies for aircraft leasing affiliates.
