生态补偿过程动态演化机制及其稳定策略研究

生态补偿是通过调节相关方的利益关系,实现可持续利用生态系统服务的一种手段或制度安排。论文从微观维度对生态补偿问题进行研究,将生态补偿利益群体分为实施群和受益群,建立非对称演化博弈模型,分析各群体利益关系的复制动态、演化稳定策略和演化博弈系统的稳定性。结果表明:在"举报惩罚"制度存在的情况下,两群体间的演化博弈存在唯一的稳定均衡策略(保护、补偿),即实施群选择"保护"策略,受益群选择"补偿"策略,其中实施群决策主导系统稳定性;利益群体各决策选择的比重是稳定均衡策略的重要影响因素,增加实施群和受益群选择"保护"和"补偿"策略的比重,可加快稳定均衡策略的有效形成。

The Dynamic Evolution Mechanism of Ecological Compensation and Its Stable Strategy Research

Ecological compensation is by adjusting the interest of the relevant parties to achieve the sustainable use of ecosystem services as a means or institutional arrangements. Based on the microscopic dimension, the thesis carried on researches on ecological compensation, established the asymmetric evolution game model through dividing interest groups of ecological compensation into the implementation group and the benefit group, and made the analysis of the replicator dynamics and evolutionary stable strategy of the relationship between interest groups and the stability of the evolutionary game system. The results showed that as the "report-punishment" system existed, there is the only stable equilibrium strategy (protection, compensation) between groups of evolutionary game, namely the implementation group chose "protection" strategy, and the benefit group chose "compensation" strategy. The implementation group of decision-making dominated system stability. The proportion of interest groups' decision choices decided whether the stable equilibrium strategy can be formed. Increasing the proportion of selecting the "protection" and "compensation" strategy by the implementation group and the benefit group, it can accelerate the formation of stable equilibrium strategy effectively.
