基于支付能力原则下CEDS的全球合作减排机制探究

A Study on the Reduction Mechanism of Global Cooperation under the Principle of Capacity to Pay Based on CEDS

文章基于支付能力原则提出一种国际差异化协调碳税政策(CEDS),在此政策下一国碳税税率与其人均GDP水平正相关;采用环境版全球贸易分析模型,定量地评估CEDS的减排效果和对不同区域的经济影响。结果表明:相比于碳关税政策,CEDS减排效果更为明显,世界碳泄露较小;与碳关税政策相比,实施全球合作的CEDS政策,世界总的GDP和居民福利均有不同程度的改善;特别的,绝大多数发展中国家福利损失较小;发展中国家基于CEDS在国内减排,也能在一定程度上降低发达国家关于单方面减排措施所导致的竞争力损失的担忧。

Based on the principle of capacity to pay, the paper proposes an international carbon tax policy （CEDS）, and there positive correlation between carbon tax and its GDP per capita. Using environmental edition model of the global trade, the paper makes an analysis of quantitative assess- ment of CEDS emission reduction effect and economic effect in different regions . The results show that, compared with the carbon tariff policy, CEDS emission reduction effect is more obvious, and the world carbon leakage is small; compared with the carbon tariff policy, the implementation of the global cooperation of CEDS policy, imploves, the world＇s total GDP and household welfare. The vast majority of the developing countries have small welfare loss and their domestic emission reduc- tion; based on CEDS.
