This paper studies the optimal low carbon production decision system with considered the constraints of carbon emission reduction policy for manufacturing enterprises producing two kinds of products in the free market. Firstly, The research proved the optimal production combination exists and it is unique under the carbon emissions limits, and next, the research analyzed the low-carbon production decision-making system in three situations, which are carbon emission trade decision, green technology input decision, and joint decision. The research results showed that carbon emission permits trade can increase more flexibility to manufacturing enterprises and increase their profits as well. However, the carbon emissions limits set by the government would have an important impact on the production decision system of manufacturing enterprises. Carbon emission permits trade and green technology investment can optimize and improve the production decision system of manufacturing enterprises to a certain extent. Meanwhile, the government's scientific and reasonable formulation of initial carbon quotas would mobilize the enthusiasm and initiative of manufacturing enterprises to participate in carbon emission reduction. The government should also guide and encourage enterprises to invest in and develop low-carbon emission reduction technologies through tax relief, so as to improve carbon emission reduction technologies and its innovations to reduce carbon dioxide emissions.

本文研究了在自由市场上生产两种产品的制造企业在考虑碳减排政策约束的情况下的最优低碳生产决策系统。首先，研究证明了最优生产组合的存在，并且在碳排放限制下是唯一的；其次，研究分析了碳排放贸易决策，绿色技术投入决策三种情况下的低碳生产决策系统。 ，并共同决定。研究结果表明，碳排放许可交易可以为制造企业增加灵活性，并增加其利润。但是，政府设定的碳排放限制将对制造企业的生产决策系统产生重要影响。碳排放权交易和绿色技术投资可以在一定程度上优化和完善制造企业的生产决策系统。同时，政府科学合理地制定初始碳配额，将调动制造企业参与减排的积极性和主动性。政府还应引导和鼓励企业通过减免税收投资和开发低碳减排技术，以改善碳减排技术及其创新以减少二氧化碳排放。科学合理地制定初始碳配额将调动制造企业参与碳减排的积极性和主动性。政府还应引导和鼓励企业通过减免税收投资和开发低碳减排技术，以改善碳减排技术及其创新以减少二氧化碳排放。科学合理地制定初始碳配额将调动制造企业参与碳减排的积极性和主动性。政府还应引导和鼓励企业通过减免税收投资和开发低碳减排技术，以改善碳减排技术及其创新以减少二氧化碳排放。
