Wasted mine revitalization through Eco-environment-oriented Development: A dynamic analysis based on differential games

A differential game model has been developed to analyze the eco-governance of wasted mines between the government and businesses, using the Eco-environment-oriented Development (EOD) model as a basis. The study has examined four models, with a focus on the investment levels in eco-governance and cleaner industry development, the pricing of cleaner products, and the resulting revenue changes for both the government and businesses. The findings indicate that the government can extend the franchise term to incentivize businesses to invest more in cleaner industrial development and the eco-governance of wasted mines. To encourage businesses to participate in environmental restoration, the government should prioritize a cooperative model. However, for wasted mines in environmentally sensitive areas where cleaner industries have limited market potential, governments can more effectively issue eco-governance subsidies under a non-cooperative model. In contrast, wasted mines in resource-depleted areas that better support cleaner industries with larger market potential, government subsidies for cleaner industrial development are more effective.
