Effect Evaluation Of Carbon Trading Mechanism On Total Factor Carbon Production Efficiency

In the context of the increasingly serious greenhouse effect,as well as “Kyoto protocol”,“Paris agreement” and other international agreements under the constraints,countries are actively promoting and improving the carbon emission reduction system.The carbon trading system based on the theory of property rights trading has been more and more popular.The carbon trading market has been gradually established and improved.The total factor carbon production efficiency index has become one of the effective indexes to measure the system operation in the carbon trading system.At present,more than 30 countries have participated in the carbon trading system,and China officially established a national carbon trading system at the end of 2017.However,China is building in the early stage of construction,and the mechanism construction is still not perfect.It is also necessary to learn from foreign excellent carbon trading experience and absorb the failed carbon trading lessons.Therefore,quantitative research methods are needed to analyze the impact of carbon trading efficiency on carbon production efficiency in various countries and contribute to foreign experience in the construction of China's carbon trading system.This paper begins with a preliminary introduction to the carbon trading system in theory.Based on this,the following research is carried out.Firstly,the global super-efficient SBM model is used to measure the total factor carbon production efficiency OECD and BRICKS.Secondly,according to the carbon trading standards set at the national level,Australia,India,Iceland,New Zealand,Norway and South Korea,which meet the requirements at the national level,are selected to conduct in-depth research on the changes of total factor carbon production efficiency before and after the establishment of carbon trading.Finally,the synthetic control method be used to evaluate the effects of carbon trading systems in six countries,including Australia,India,Iceland,New Zealand,Norway and South Korea,on total factor carbon production efficiency.The accuracy of the assessment be further verified by replacement and sequencing tests for the six countries.The study find that the OECD and BRICKS countries show overall upward trend of convergence and convergence in total factor carbon production efficiency.Six countries,including Australia,India,Iceland,New Zealand,Norway and South Korea,show two different trends from the year when the carbon trading system was established.The total factor carbon production efficiency of Iceland and Norway showed a downward trend,while the total factor carbon production efficiency of Australia,India,New Zealand and South Korea showed an upward trend.The six countries show three different impact results in the evaluation of synthetic control law.Among them,the carbon trading system of Australia and India played a positive role in improving the efficiency of total factor carbon production in the country.The cumulative effect is about 5.08% and 9.02% of the actual value.However,because of the establishment of the carbon trading system,South Korea has inhibited the original increase in the efficiency of the country's total factor carbon production,and the cumulative effect is about 6.81% of the true value.New Zealand's total factor carbon production efficiency shows that it is not immune to the country's carbon trading system.The effects of Iceland and Norway cannot be synthesized and cannot be explored.According to the research results of this paper,the improvement direction of carbon production efficiency under carbon trading is proposed from the three perspectives of promoting national low-carbon development,effectively formulating specific policies for carbon trading system and optimizing the domestic energy industry structure.Provide experience guidance to countries that have not yet established a national carbon trading system.
