<p>Charging infrastructure serves as a fundamental pillar for the development of the electric vehicle industry and plays a critical role in advancing economic, environmental, and social sustainability goals in the transportation sector. This paper develops an evolutionary game model on dual-layer complex networks from the perspectives of both market supply and demand to investigate the deployment of charging infrastructure. The analysis reveals the dynamic influences of investment subsidies, construction subsidies, operating subsidies, green loans, and consumer demand. The results demonstrate that government subsidies and green finance policies serve as pivotal drivers of infrastructure expansion. Specifically, investment subsidies emerge as the most potent stimulus for deployment, while construction subsidies are effective only beyond a critical threshold. Operating subsidies exert a relatively stable incentive effect, and green loans, by alleviating financing constraints, further facilitate infrastructure investment. Notably, the growth of environmentally conscious consumers stimulates the deployment of charging infrastructure; however, reliance solely on charging or vehicle purchase subsidies cannot ensure sustainable development. These findings highlight the need for governments to accelerate the transition from purchase subsidies to construction subsidies. In parallel, strengthening institutional financing and fostering social mechanisms are crucial for the effective diffusion of charging infrastructure.</p>
