Considering the policies surrounding carbon trading, decarbonization plans have been regarded as imperative choices for the manufacturing industry. However, there has been little research into combining the concrete carbon quota allocation methods with the low-carbon supply chain. Still, the distinction between ordinary and low-carbon manufacturers has been scarcely investigated. To fill these gaps, drawing on two quota allocation methods—grandfathering and benchmarking, we model the supply chains under two production modes, which consists of an ordinary manufacturer, a low-carbon manufacturer and a hybrid manufacturer. Our primary conclusions are listed here. The carbon emission reduction level (CERL) shall fluctuate within an acceptable scope to prevent adverse consequences on total social welfare. Additionally, independent of the production mode, manufacturers' profits will peak when the gross carbon quotas meet certain values under grandfathering. Meanwhile, under benchmarking, the environmental performance and consumer surpluses are better when the benchmark quota reaches a certain value.

碳交易政策下制造商的减排水平


考虑到围绕碳交易的政策，脱碳计划一直被视为制造业的当务之急选择。然而，关于将具体的碳配额分配方法与低碳供应链相结合的研究很少。尽管如此，普通制造商和低碳制造商之间的区别几乎没有得到研究。为了填补这些空白，我们利用两种配额分配方法——祖父式和基准化，对两种生产模式下的供应链进行建模，包括普通制造商、低碳制造商和混合制造商。我们的主要结论列在这里。碳减排水平 （CERL） 应在可接受的范围内波动，以防止对社会总福利产生不利影响。此外，无论生产方式如何，当总碳配额达到祖父制下的一定值时，制造商的利润将达到峰值。同时，在对标下，当基准配额达到一定值时，环境绩效和消费者剩余会更好。
