摘要
在碳排放交易背景下,中国碳排放效率的趋势变动成为政府重点关注的目标,科学考察我国碳排放效率水平,分析碳交易试点启动对低碳发展是否具有促进作用具有重要的理论价值和明确的现实意义。基于投入产出的生产函数思想,本文利用三阶段DEA模型对碳交易市场建立前后的中国碳排放效率进行评价并排序,并利用收敛性原理对中国各省区碳排放效率的差异进行分析。研究结果显示:(1)碳交易市场启动对碳排放效率有一定的提升作用,中国碳交易试点地区碳排放效率排名均保持不变或有所上升。(2)从全国平均水平来看,中国各省区碳排放效率较低是由于纯技术效率引起的,技术效率应用程度还处于中低端状态,改善空间很大。(3)从全国整体效果来看,广东省一直处于生产前沿面上,碳排放效率最高,而宁夏、青海和陕西省稳居后三名。(4)中国碳排放效率水平还存在一定的改进空间,而在纯技术效率水平上需要改进的空间更大。(5)碳交易试点建立前,中国各省区的碳排放效率差距在逐渐缩小,试点交易市场建立后,差距逐渐增大。(6)城市化程度会拉大省区之间的碳排放效率差距,不利于碳排放效率的收敛。本文研究结论显示,我国需要坚持完善全国碳交易市场,借鉴试点经验,加强内部监管,形成严格有效的交易制度;不断调整地区间的差距,加强合作,由发达地区带动落后地区,促进全国统筹发展;优化产业结构,促进低碳绿色发展机制,扩大清洁能源的使用范围。
As the world’s largest carbon emitter,China has adopted carbon emissions trading as an important measure for energy conservation and emission reduction.In the context of carbon emissions trading,the trend of China’s carbon emission efficiency has become the government’s key target,scientifically examining China’s carbon emission efficiency level and analyzing whether the initiation of carbon trading pilots has a positive theoretical value and clear realistic meaning for promoting low-carbon development.Based on the input-output production function idea,this paper used the three-stage DEA model to evaluate and rank China’s carbon emission efficiency before and after the carbon trading market is established,and used the convergence principle to analyze the differences in carbon emission efficiency among provinces in China.The results of the study showed that:①The start of the carbon trading market had a certain effect on the carbon emission efficiency.The carbon emission efficiency rankings in China’s carbon trading pilot areas remained unchanged or increased.②From the perspective of the national average level,the low carbon emission efficiency of China’s provinces was caused by the pure technical efficiency.The application degree of technical efficiency was still at the middle and low level,and there is much room for improvement.③From the overall national effect,Guangdong Province had been on the production frontier and had the highest carbon emission efficiency.Ningxia,Qinghai and Shaanxi were stable in the last three places.④There was still room for improvement in China’s carbon emission efficiency level,and there was more room for improvement in pure technical efficiency level.⑤Before the pilot carbon trading system was established,China’s carbon emission efficiency gap between provinces was gradually narrowed,and after the pilot trading market was established,the gap gradually increased.⑥The degree of urbanization would widen the carbon emission efficiency gap between provinces,which was not conducive to the convergence of carbon emission efficiency.This paper drew conclusions that China needs to persist in improving the national carbon trading market,learn from the pilot experience,strengthen internal supervision,and form a strict and effective trading system;constantly adjust the gaps between regions,strengthen cooperation,promote the backward regions by developed regions,and promote the overall development of the country;optimize the industrial structure,promote the development mechanism of low-carbon green,and expand the use of clean energy.
