利用边际减排成本曲线分析国际碳交易理论逻辑,并预测“附件B国家”间自由交易结果,然后构建无谓损失和进口成本节约理论模型分析国际碳交易市场需求垄断效应,证实碳排放权进口国设定最高进口比例可以减少完成减排义务的总成本,扩大国际碳交易净收益,而且存在使总成本最小的进口比例。发展中国家应该加强合作与碳资源管理,争取国际碳交易和减排谈判的话语权,同时应尽快进行相关产权制度创新,建立国内市场化交易机制。 Using the marginal abatement cost curve to analyze the theoretical logic of international carbon trading and forecasting the results of free trade between “Annex B countries”, and then constructing the theoretical model of deadweight loss and import cost saving to analyze the monopoly effect of demand in the international carbon trading market and confirm the carbon emission right Importing countries to set the maximum import ratio can reduce the total cost of completing the emission reduction obligations, expand the net gains of international carbon trading, and there is the lowest total cost of imports. Developing countries should strengthen cooperation and carbon resource management and strive for the right of speech in international carbon trading and emission reduction negotiations. At the same time, they should innovate relevant property rights system as soon as possible and establish a domestic market-oriented trading mechanism.
