碳汇与碳排放权的交易价值比较分析

Comparative Analysis on the Transaction Value of Carbon Sink and Carbon Emission Rights

摘要: 为应对全球气候变暖问题，中国提出“碳中和”远景目标，并逐步构建全国碳交易市场。目前国内碳交易主要以碳排放权交易为主，而碳汇交易开展十分有限。基于投入产出分析模型对我国完全碳排放量进行核算，以影子定价法确定我国碳汇单位价格，本文估计了我国碳汇交易价值，并与碳排放权交易价值进行比较分析。结果表明：碳汇交易价值远高于碳排放权交易价值，我国开展碳汇交易既能创造巨大经济价值，又能有效实现碳减排。

Abstract: In order to deal with the problem of global warming, China puts forward the long-term goal of “car-bon neutralization” and gradually constructs a national carbon trading market. At present, domes-tic carbon trading mainly focuses on carbon emission rights trading, while carbon sink trading is really limited. Based on the Input-Output Analysis Model, China’s complete carbon emissions are calculated, and the unit price of China’s carbon sink is determined by the Shadow Pricing Method. The paper estimates the transaction value of China’s carbon sink, and compares it with the transac-tion value of carbon emission rights. The results show that the value of carbon sink transaction is much higher than that of carbon emission rights transaction. China’s carbon sink transaction can not only create great economic value but also effectively realize carbon emission reduction.
