本文通过建立我国森林碳汇供给、需求曲线模型及对供给、需求的阶段性弹性分析,发现我国的碳汇吸收总量远远小于不断上升的碳源排放量,是典型的碳源型国家。在完全竞争的市场条件下,当价格为X时,S=D,是市场出清,此时具有帕累托效率。在完全价格歧视的垄断条件下,碳汇稀缺的林权所有者可根据消费者(碳源)愿意出的价格差别定价,消费者剩余全归林权所有者(碳汇)所有,碳汇的生产者剩余最大并促进了碳汇的整体提升,这时也是帕累托最优。因此,建立市场经济方式(而不是2C式)的完全竞争性质的碳汇交易市场,才是促进节能减排、新能源替代和碳中和三位一体的诀窍或关键所在。
本文通過建立我國森林碳彙供給、需求麯線模型及對供給、需求的階段性彈性分析,髮現我國的碳彙吸收總量遠遠小于不斷上升的碳源排放量,是典型的碳源型國傢。在完全競爭的市場條件下,噹價格為X時,S=D,是市場齣清,此時具有帕纍託效率。在完全價格歧視的壟斷條件下,碳彙稀缺的林權所有者可根據消費者(碳源)願意齣的價格差彆定價,消費者剩餘全歸林權所有者(碳彙)所有,碳彙的生產者剩餘最大併促進瞭碳彙的整體提升,這時也是帕纍託最優。因此,建立市場經濟方式(而不是2C式)的完全競爭性質的碳彙交易市場,纔是促進節能減排、新能源替代和碳中和三位一體的訣纖或關鍵所在。

By establishing China’s forest carbon sequestration supply and demand curve model and analyzing the stage elasticity of supply and demand, we’ve found that China is a typical carbon source country as its carbon absorption amount is far less than that of the rising carbon emissions. In the condition of a complete competition market, when the price is X while S=D, it is market clearing and there is a Pareto efficiency. In the monopoly condition of price discrimination, the forest owner with scarce carbon sequestration can make the price according to the different prices that the consumers (carbon source) are willing to offer. As the surplus left by the consumers belongs to the forest owner (carbon sequestration), the carbon sequestration producer has the maximum surplus and facilitates the overall increase of the carbon sequestration. This is also Pareto optimal. Therefore, to establish a carbon trading market with competitive market economy mode instead of “2C command”is the key to promote en-ergy-saving emission reduction, new energy substitution and carbon neutral.
