文章摘要：微觀企業(yè)面對(duì)減排約束時(shí)的行為選擇對(duì)于減排成本產(chǎn)生直接影響，從而導(dǎo)致不確定性條件下數(shù)量控制與價(jià)格控制政策實(shí)施的有效性出現(xiàn)差異。本文將這一機(jī)制的理論模型納入一般均衡分析框架，構(gòu)建中國多區(qū)域動(dòng)態(tài)一般均衡模型，模擬分析了各省市從2007年至2020年的邊際減排成本曲線，并就其對(duì)溫室氣體控排的碳排放權(quán)交易與碳稅政策的選擇進(jìn)行了研究。本文發(fā)現(xiàn)，一方面邊際減排成本曲線的斜率會(huì)隨著減排行動(dòng)的推進(jìn)而逐漸增大，另一方面也會(huì)出現(xiàn)拐點(diǎn)并進(jìn)一步上翹，且不同省市其邊際減排成本曲線上翹的幅度以及出現(xiàn)拐點(diǎn)的位置均存在差異。由于在信息不完全條件下，，數(shù)量政策更適用于邊際減排成本較為平緩的情況，中國各省市邊際減排成本曲線的動(dòng)態(tài)特征說明碳排放權(quán)總量控制與交易機(jī)制更適用于現(xiàn)階段中國實(shí)際；隨著未來減排力度的加強(qiáng)，則要進(jìn)一步考慮將碳稅政策引入低碳政策體系中。

Abstr：When facing with emission constraint, firm＇s optimal behavior will be changed and thus affect abatement cost directly. As a result, the effectiveness of quantity control policy and price control policy will be different under this situation with uncertainty. This paper introduces this micro-mechanism into the dynamic regional computable general equilibrium model of China to simulate each region＇s marginal abatement cost curve from year 2007 to 2020 and study the choice between emission trading policy and carbon tax policy. Firstly, the results show that the slopes of each region＇s MAC curve will increase gradually and MAC curves will occur kink points. Secondly, slopes on both sides of MAC curve are different and kink points will move due to tighter emission constraint. For the reason that quantity control policy is more suitable than price control policy when there exists uncertainty and the slope of MAC curve is flat, the results imply that emission trading scheme is more applicable currently in China. But when emission target becomes more stringent in the future, policy makers should also introduce carbon tax into low carbon policy system.
