碳管制与交易政策下企业生产管理优化问题

Production Management Optimization Problem under Carbon Cap and Trade Policy

碳管制与交易政策是一种有效的减排政策。首先研究了在碳管制与交易政策下,企业的最佳生产量和相应的期望利润,并且分析了碳管制与交易政策对企业管理和决策的影响。由于考虑了碳足迹的限制,企业的最优生产量要小于仅仅以利润为目标的最优生产量,且存在一个与企业碳交易相关的阈值。当该阈值超过、等于或小于碳限额时,企业可以买入、卖出碳权或不进行交易,此外分析了碳限额、碳价、碳足迹对最佳生产量和企业总利润的影响。最后,通过仿真数值分析验证了理论的有效性,同时对研究结果做出了具有现实意义的评价与解释。

Carbon cap and trade mechanism is an efficient policy to reduce carbon emission. In this paper, a company＇s optimal production quantity and its profit are studied under the carbon cap and trade policy, and also analyzed the effect of this policy on company＇s strategic decision-making. Because of the limitation of the carbon footprint, the optimal production quantity of a company is less then the amount when the total profit is the only target. There exists a threshold related to the carbon trading, when the threshold is more than, equal to or less than the carbon cap, the company could buy, sell the carbon credits or not to trade. Besides, this paper also examines the impacts of carbon cap, carbon price, and carbon footprint on optimal production quantity and the total profit. Furthermore we make interesting observations from the numerical examples and provide managerial insights from the analytical results.
