In recent years, due to global climate change, increasing resource scarcity, and environmental constraints, countries have prioritized energy conservation and emissions reduction. However, enterprises are primarily responsible for energy saving and emissions reduction. To encourage industrial enterprises to engage in energy conservation and emissions reduction, high-carbon enterprises must purchase carbon emission rights from low-carbon counterparts. Common modes of energy conservation and emission reduction of industrial enterprises include reducing production scale, improving energy utilization efficiency, and expanding renewable energy. This article constructs three differential game models to identify the applicable scope of various energy conservation and emission reduction strategies, comparing and analyzing the equilibrium results. The study concludes that when the cost of changing the production mode and the income obtained from the production of unit product is large, the low-carbon enterprise can obtain the maximum benefit by reducing the production scale mode. Otherwise, low carbon enterprises can be maximized through improving energy efficiency mode. For both low-carbon and high-carbon enterprises, reducing production scale is the fastest way to enhance efficiency when the costs of energy conservation and emission reduction are substantial.
近年来，由于全球气候变化、资源日益短缺和环境限制，各国都将节能减排作为优先事项。然而，企业是节能减排的主要责任方。为了鼓励工业企业参与节能减排，高碳企业必须从低碳企业购买碳排放权。工业企业常见的节能减排模式包括降低生产规模、提高能源利用效率和扩大可再生能源。本文构建了三个微分博弈模型，以确定各种节能减排策略的适用范围，并对均衡结果进行了比较和分析。研究得出的结论是，当改变生产模式的成本和单位产品生产的收益较大时，低碳企业可以通过降低生产规模模式获得最大利益。否则，低碳企业可以通过提高能源效率模式实现最大化。对于低碳和高碳企业而言，当节能减排成本较高时，降低生产规模是提高效率的最快途径。
