| With the sustainable development of China's economy,carbon dioxide emission has become a key issue that restricts the sustainable development of economy,society and environment.Steel industry as a pillar industry to the national economic development contribution is obvious,but its energy consumption,carbon dioxide emissions and pollution to the environment can not be underestimated.How to protect the environment while developing is an urgent problem to be solved in heavy pollution industry including iron and steel industry.To reduce emissions and protect the environment is a cost.Only when enterprises grasp their emission reduction costs accurately,can they put forward their future development and emission reduction plans.This paper should take this opportunity.Calculate the marginal carbon dioxide emission reduction costs of listed steel companies for the government to formulate carbon trading rules for iron and steel enterprises to formulate targeted carbon emission reduction strategy to provide decision-making support.Firstly,the paper analyzes the economic development,energy consumption,carbon emissions and carbon emission reduction of the steel industry and listed steel companies.Secondly,we draw lessons from the nonparametric directional distance function(DDF)and data Envelopment Analysis(DEA).Based on the main input-output data of 22 listed iron and steel companies from 2010 to 2016,a DDF model which can comprehensively reflect the carbon emission reduction performance and marginal emission reduction costs is constructed.The marginal carbon emission reduction costs of 22 listed steel companies from 2010 to 2016 are calculated and the marginal carbon emission reduction costs of each listed company in 2020 are predicted.Thirdly,the regional differences of marginal carbon emission reduction costs of listed companies are calculated by using the Theil index decomposition method.Finally,according to the decomposition results of Theil index,this paper analyzes the... |
