碳配额分配方法对授权再制造影响研究

The effect of carbon allowance allocation methods on authorized remanufacturing

不同碳配额分配方法直接影响碳交易政策的实施效果,对制造/再制造生产决策以及碳交易市场运营产生不同影响.为分析不同碳配额分配方法对制造/再制造影响,基于两种典型碳配额分配方法(历史排放分配法和基准分配法)构建碳交易下原始制造商与授权再制造商博弈模型.研究主要得到:1)在单位新产品碳排放量、碳交易价格与基准碳配额满足一定条件时,原始制造商会选择碳减排投资,且基准分配法更能提高原始制造商碳减排积极性;2)当碳配额以及碳交易价格满足一定条件时,碳交易能够同时促进各方收益增加;3)适当提高碳交易价格能推动减排工作顺利进行,但两种碳配额分配方法下的总环境影响与原始制造商减排投资水平、碳交易价格等相关.

Different carbon allowance allocation rules will directly affect the implementation of carbon trading policy,leading to different effects on manufacturers'production decisions and the operation of carbon trading market.This article constructs game models between an original equipment manufacturer(OEM)and an authorized remanufacturer to analyze the impacts of two different carbon allowance allocation rules(grandfathering and benchmarking)on the authorized remanufacturing supply chain.The main conclusions are as follows.1)The OEM will make emissions reduction investments when the carbon emission per unit of new products,the carbon trading price,and the benchmark carbon quota meet certain conditions,and the benchmarking mechanism can improve the OEM's initiative to reduce emissions.2)When carbon allowance and carbon trading price meet certain conditions,carbon trading policy can increase the benefits of all parties in the supply chain.3)An appropriate increase in carbon trading price can promote emission reduction,but the total environmental impact of the two carbon allowance allocation rules is also related to the level of the OEM's emission reduction investment and carbon trading price.
