Research On Provincial Green Development Evaluation Based On “full Carbon” Accountin

Carbon emissions are closely linked to economic development,which requires carbon consumption from all walks of life.On Sunday,CO2 emissions from various countries led to soaring greenhouse gases,global climate warming,and climate change became a global problem.In this context,China promised to bring CO2 emissions to a peak in 2030 and no longer increase;to take targeted emissions reduction measures by 2060 to offset CO2 emissions and achieve "carbon neutrality".Green and low-carbon development is unstoppable in the road of realizing national high-quality economic development.The appropriate green evaluation method has macro-strategic significance for the national low-carbon and green development.To this end,this study takes 30 provinces as the research target,takes the goal of evaluating regional green economy efficiency as the goal,constructs the whole-carbon efficiency index,and analyzes the differences in carbon efficiency in each province,so as to achieve "net zero emissions" as soon as possible.The main work is as follows:First.Increase carbon sink accounts and improve the all-carbon accounting system.This study of "full carbon" accounting is based on energy analysis theory and energy conversion law,direct carbon emissions,energy consumption potential carbon consumption and carbon consolidation woodland carbon sink into the "whole carbon" accounting account,normalized different substances to carbon equivalent,and evaluate the green economy on the basis of carbon efficiency.First,based on the results of this research group on whole carbon emissions,this paper calculates the traditional energy carbon emission and waste resource emissions,and simplifies the biomass resource emissions.Although biomass resources,as an indispensable part of carbon emissions,lack research feasibility because they account for about 20% of air pollution emissions and national data are difficult to obtain.Therefore,the carbon emission caliber range only measures the traditional energy carbon emissions and waste emissions.Secondly,the addition of carbon sink account--woodland carbon fixation,the reason is that in the land carbon sink composition,woodland carbon sink accounts for about 80%,the rest of the main carbon sink are wetland,grassland and soil.And the inclusion of the Paris Agreement forest as a separate clause means the high recognition of the international community of the top role of woodland in the road to tackling warming and achieving carbon neutrality.To sum up,the "all-carbon" accounting account consists of three parts: traditional energy carbon discharge,waste carbon discharge and woodland carbon sink.Thirdly,the corresponding carbon emission measurement method is found according to different account characteristics,where energy consumption carbon consumption adopts the traditional carbon emission coefficient method;waste resource potential carbon consumption is converted into energy value analysis method,then energy value into carbon;forest land carbon fixation utilization biomass conversion method,from forest stock to biomass,using expanded coefficient to forest land biomass,and finally converted into carbon.Finally,the carbon emissions of the three subaccounts were summarized and reduced,and different kinds of substances were converted into carbon equivalents for measures of all-carbon efficiency.This method solves the problem of different types of resource and environmental factors,objective empowerment,and the overall efficiency cannot be accurately evaluated,which lays a foundation for the scientific evaluation of provincial green economy,and provides ideas for further all-carbon research.Second,evaluate the efficiency of green economy in each province.Firstly,based on the "all carbon" accounting model,consider the economic output efficiency,that is,GDP output per unit carbon emission.The larger the output of unit carbon emission GDP,the higher the output level of human resources and the higher the carbon economic efficiency.At the same time,social efficiency is considered.First,the carrying capacity of unit carbon emission population represents the occupation of human resources for social resources.The greater the carrying capacity of unit carbon emission,the less carbon environment occupation per person and the higher the carbon efficiency;Second,the disposable income per carbon emitter.The amount of disposable income represented by the per capita carbon footprint can reflect the level of personal welfare.The higher the disposable income per carbon emitter,the higher the carbon socio-economic efficiency.In this paper,the total carbon efficiency index is calculated based on the average weight and coordination degree of the above three indexes.Total carbon efficiency index refers to taking carbon as an implicit potential material input from the perspective of economics,and then measuring the output created by an economic unit consuming unit carbon resources.Therefore,the index is used to evaluate the carbon efficiency of all provinces in China.Secondly,based on DEA model and relative quantity as the main index,the input-output efficiency of regional eco-economic system is evaluated.The short board factors restricting the improvement of total carbon efficiency are analyzed,so as to provide decision-making basis for improving carbon efficiency and realizing the development of green economy.Thirdly,the DEA Malmquist model is used to analyze the total factor productivity of national carbon efficiency,find its power factors and resistance factors,and provide a basis for further improving total carbon efficiency.Finally,DEA-ESDA model is used to analyze whether there is spatial correlation in national carbon efficiency,and Lisa diagram is used to visualize,explain and find the existing spatial agglomeration,so as to play its radiation role and improve the efficiency of green economy.Third,put forward corresponding improvement suggestions for some provinces.The whole is divided into three categories: for the central and eastern provinces with large population and relatively developed economy,we should improve the level of scientific and Technological Development and resource utilization efficiency;For the northwest province with extensive production mode,it is necessary to change the production mode,reduce the consumption of traditional energy,make use of its own geographical location,develop clean energy,extend the industrial chain and enhance the added value of products,so as to enhance the output value of the overall economy;For the southwest provinces with unique advantages in forestry resources,we should closely link the concept of forest wealth with economic development,vigorously develop the agricultural,forestry and pharmaceutical industry,promote industrial transformation and help economic development.The common constraints among provinces are: large traditional energy consumption.This indicates that China’s energy consumption structure dominated by coal has not been fundamentally changed and still consumes a large amount of fossil energy.In view of the current development situation,it is imperative to develop clean energy and introduce energy-saving and emission reduction technologies.At the same time,it is necessary to rectify industries with high energy consumption and high pollution,eliminate backward production capacity,so as to improve energy efficiency and carbon efficiency,so as to realize the development of green economy.
