碳排放总量控制下行业间碳配额分配的博弈机制研究

为了向实现2030年中国碳减排目标提供参考,构建了某省内行业间的配额分配权重的不完全信息动态博弈模型,将该省内参与配额分配的行业根据减排严格程度分为低、中、高3个等级,通过引入行业减排优先顺序和配额分配权重构建各行业配额分配支付函数,并通过逆向归纳法求得博弈模型的纳什均衡。最后为了辅助实施减排,控制排放总量,引入了激励与约束机制。研究结果表明：行业减排优先顺序和分配权重的引入使最终的分配结果不仅考虑了行业的历史减排量,而且将行业减排责任考虑在内,体现了我国共同但有差别的责任原则,从而使得分配结果更为科学合理;为避免各行业为追求经济效益而缺乏减排驱动力引入奖惩机制,使得配额分配后的减排政策能够更加有效地实施。

Carbon quota allocation among industries with carbon emission control by using game model

To achieve China's carbon emission reduction target in 2030, one dynamic game model of quota allocation weight among industries is constructed. Firstly, by introducing the priority of industry emission reduction and the weight of quota allocation, the payment function of each industry quota allocation is constructed. Secondly, with backward induction, the Nash equilibrium of the game model is obtained. Finally, incentive mechanism are introduced for better emission reduction policy making. The results show that the introduction of emission reduction priority and distribution weight makes the final distribution results more scientific and reasonable.
