Regional Carbon Emissions,Economic Development And Environmental Protection Coupling In Liaoning Province

With the carbon emissions rapid increased,the conflict developed among carbon emissions,economic development,and environmental protection.Liaoning Province is a typical province with high energy consumption,economic burden and environmental pollution.Therefore,the research has become a new breakthrough,which in alleviating the contradiction between the social economy and the environment.In this paper,based on the three stage DEA model,we can calculate carbon emissions efficiency which is divided into technical efficiency,pure technical efficiency,and scale efficiency of 14 cities in Liaoning Province from 2004 to 2015.Then three coupling model was established to analyze the relationship among of the carbon emissions,economic development,and environmental protection.Meanwhile,GM(1.1)forecast model was also used to analyze 3E system coupling in Liaoning province from 2016 to 2020,but the results are not optimistic.Based on the forecast results,it is necessary for Liaoning Province to take corresponding measures to solve these problems.The results show that the 3E system coupling in Liaoning province is still at a low level.Of all the cities in Liaoning province,Shenyang and Dalian have been leading all the time.In other twelve cities,Anshan,Fushun,Dandong,Jinzhou,Yingkou,Liaoyang,Panjin,Fuxin,Tieling,Huludao show moderate levels;while Benxi,Chaoyang have the lowest level.The coupling degree of 3E system has been promoted during these twelve years.However,the level of 3E system coupling is still low,which has a big margin for improvement.According to the conclusion,taking carbon emissions efficiency as the evaluation index of carbon emissions system is suitable,and the results are coincide with actual situation in Liaoning Province.In order to improve the coupling degree of 3E system and reduce regional differences,the author believes that all the regions should unify their own actual development situation,compare superiority and make science formulation development policy.Overall,every city should take appropriate measures to promote region carbon emissions,economic development,and environmental protection.
