碳排放权交易市场中的交易成本分析

Analysis on Transactions Costs of Carbon Emissions Trading Market

我国碳排放权交易市场面临着交易不活跃、遵约企业参与积极性不高等问题,而交易成本是原因之一。通过分析发现,如果边际交易成本不变,排放权的初始分配不会影响市场效率;但当边际交易成本增加时,交易成本的存在使得厂商的边际治理成本与排放权的市场价格不相等,影响排放权交易的效率,导致实际发生的排放权交易数量大大低于理论数值。

China＇s carbon emissions trading market is very immature, of which the transaction is inactive, price fluctuations are great, the contracts are not uniform.It can be found that transaction cost is one of the reasons.Analysis shows that in a competitive market with the marginal transaction cost unchanged,the initial distribution of permits has no impact on the cost-effectiveness of final abatement. Otherwise, if the marginal transaction cost increases, the initial distribution of permits can affect both abatement costs and equity, and amount of actual trading is far lower than the theoretical value.
