碳税与减排技术投资下制造企业生产-库存运营策略

Manufacturing Enterprise Production-Inventory Operation Strategy under Carbon Tax and Emissions Reducing Technology Investment

摘要:

我国预计将于2020年，全面扩大碳交易体系并开征碳税，这势必为制造企业运营产生重要影响。为分析碳税机制下企业生产与库存运营调整，以及企业主动实行碳减排技术投资所产生的影响，本文基于经典Arrow-Karlin动态模型研究无碳排放约束、碳税机制、实行减排技术投资三种情景下制造企业生产-库存变化，分析模型数理特性，运用庞特里亚金极大值原理和前向Arrow-Karlin算法求解模型。得出碳税机制下，实行减排技术投资时企业的生产与库存水平最佳。随着减排技术投资增加，企业碳排放数量减少，但存在边际投资减排递减规律。

Abstract:

In 2020, carbon trading system will be fully amplified and introduced a carbon tax in China, which is bound to an important impact for manufacturing enterprise operation. In order to analyze the enterprise operation adjustment for production and inventory under carbon tax mechanism, and the impact implemented actively the carbon emission reduction technology investment. In this paper, manufacturing enterprise production-inventory changes with three scenarios, which includes no carbon emissions constraints, a carbon tax mechanism and emissions reducing technology investment, was studied on the basis of the classic Arrow-Karlin dynamic model. To investigate mathematical characteristics of the model. Pontryagin Maximum Principle and forward Arrow-Karlin algorithm were used to solve the model. It was concluded that enterprise production and inventory level was optimal when implementing emission reducing technology investment under carbon tax mechanism. With increases investment in emissions reduction technology, the number of carbon emissions decreases, but exists the law of diminishing marginal investment to reduce emissions.
