企业碳配额视角下减排技术投入研究

以政府碳配额和碳减排技术投资补贴政策为背景,针对供应链企业的碳减排技术投入行为与企业的合作关系问题,运用博弈和最优化方法构建无协调机制、合作博弈、集中决策和社会福利最大化状态下的决策模型,并采用逆向归纳法对模型进行求解。对各种状态下的减排努力水平、企业利润和社会福利进行分析和对比,并探讨减排投入成本等参数对其的影响,最后通过数值仿真证明模型的有效性,以期为供应链企业选择最优合作策略选择和政府补贴政策的设计提供理论支撑。

Research on investment of emission reduction technology from perspective of carbon quota of enterprises

In the context of the government carbon quota and carbon emission reduction technology investment subsidy policy, the relationship issues are considering between carbon emission reduction technology investment behavior and enterprise cooperation in supply chain enterprises. By using the game and the optimization methods, the decision models are constructed under the states of no coordination mechanism, collaborative game theory, centralized decision making and social welfare maximization. The models are solved by backward induction. Analysis and contrast are made concerning the levels of emission reduction efforts, the corporate profits and social welfare in all states. And the influence of the parameters such as emission reduction investment and cost is discussed. Finally the effectiveness of the model is proved by numerical simulation, so as to provide theoretical support for the selection of optimal cooperation strategy and the design of government subsidy policy for supply chain enterprises.
