Carbon Emission Efficiency Evaluation And Influence Factors Of Huaihe River Ecological Economic Belt

The carbon emission efficiency reflects a kind of energy utilization efficiency,it reflects the carbon emission caused by the production efficiency.The higher the efficiency of carbon emission,the higher the comprehensive efficiency of energy utilization.With the convening of the 19 th national congress of the communist party of China and the promotion of Huaihe river ecological economic belt as a national strategy,the role of Huaihe river ecological economic belt in promoting economic development in the central and eastern regions cannot be ignored.While pursuing economic development,it will produce a large amount of energy consumption,and the negative impact of carbon dioxide on the environment is also increasingly apparent.Under the background of China's low-carbon economic development,It is of great practical significance to study the carbon emission efficiency of Huaihe river ecological economic belt.This paper carefully summarizes and analyzes the existing research results,according to the theory of sustainable development,low carbon economics disciplines knowledge as the support,guided by the policy spirit of the the 18 th and 19 th national congress of the communist party of China application of the expected output SBM models,and Malmquist index and spatial econometric model,the ecological economic zone of the Huaihe river system of the effect of carbon efficiency and its influencing factors.The main contents and conclusions are as follows:Carbon emission efficiency measure.In this paper,panel data from 2013 to 2017 were selected to calculate the total carbon emissions of cities along the Huaihe river eco-economic belt,and the carbon emission efficiency value of each city was measured by using the non-expected output SBM model.Then,the reasons for the change of carbon emission efficiency value were obtained based on decomposition.The results show that the total carbon emission of Huaihe river ecological economic belt shows a decreasing trend,among which jining city has the largest total carbon emission.The total carbon emission efficiency of Huaihe river eco-economic belt is on the rise tendency,and the annual carbon emission efficiency of most cities is between 0.4 and 0.8.The results of Malmquist index decomposition indicate that the technological progress is the main factor causing the change of carbon emission efficiency in the Huaihe river eco-economic belt.Analysis of factors affecting carbon emission efficiency.Firstly,the global and local moran index tests show that the carbon emission efficiency of Huaihe river eco-economic belt shows a significant positive spatial autocorrelation.Most cities in Huaihe river ecological economic belt have spatial dependence and some differences.Second,urbanization rate,energy intensity,science and technology innovation,industrial structure and the level of opening to the outside world as carbon and spatial econometric analysis to the influence factors of the efficiency,and select the doberman model for the optimal fitting model,the results showed that the urbanization rate of positive direct effect,indirect effect value is negative,the city's urbanization rate,the higher the information of the city to promote the efficiency of carbon emissions has significant role in promoting,and to other cities to enhance the efficiency of carbon inhibition;The direct effect value of the industrial structure is negative,while the indirect effect value is positive,indicating that the increase of the proportion of the secondary industry in the total industrial value of a city has an inhibitory effect on the improvement of the carbon emission efficiency of that city,and an promoting effect on the carbon emission efficiency of other cities.The direct effect value of energy intensity is positive,that is,the higher the energy consumption per unit GDP of a city is,the higher the carbon emission efficiency of the city will be inhibited.The direct effect value and indirect effect value of technological innovation are both positive,indicating that the higher the proportion of R&D expenditure in GDP in a city,the higher the carbon emission efficiency of that city will be promoted,and the higher the carbon emission efficiency of other cities will also be promoted.The direct effect value of the level of opening to the outside world is positive,indicating that the level of opening to the outside world has a promoting effect on the improvement of the carbon emission efficiency of the city.Policy Suggestions on improving the carbon emission efficiency of Huaihe river eco-economic belt.In order to improve the carbon emission efficiency of Huaihe river eco-economic belt,Suggestions are put forward from four aspects: effective planning of urbanization development,accelerating the optimization of industrial structure,increasing technological innovation and optimizing the quality of foreign investment.
