On mine ecological restoration mechanisms based on multi-stakeholder cooperative game theory

This study starts from the perspective of stakeholders, clarifies the interactive relationship between the government, mining enterprises, and residents in mining areas, and constructs a cooperative governance mechanism for mine ecological restoration. The game relationship is analyzed through a cooperative game model. The results indicate that: (1) The existing repair models cannot meet the reasonable repair needs, and there is an urgent need to transform from a single dominant model to diversified cooperative governance. (2) Through the Shapley value benefit distribution model analysis, it was found that when the three parties actively participate in cooperation, the benefits are optimal, and the ideal distribution ratio is one-third each, which can promote positive interaction among the three parties. (3) Taking Qidong Duijiachong Iron Mine in Hunan province as an empirical case, the results show that the benefits of tripartite cooperation are significantly higher than those of non cooperation or two-way cooperation. (4) The revised Shapley value was used to verify that the distribution of benefits under cooperation can effectively promote the realization of mine ecological restoration. Cooperative governance conforms to the modernization trend of ecological governance in China, can balance the conflicts of interests among multiple stakeholders, and provide reference for optimizing ecological restoration mechanisms.
