The Spatial Difference Research On Carbon Emission Intensity Of Urban Residential Building In China

Under the international background of coping with climate change,China is faced with huge pressure of carbon emission reduction,which requires the joint efforts of all domestic industries and targeted implementation to key areas.In recent years,with the continuous advancement of China’s urbanization process,the carbon emissions of urban residential buildings keep increasing year by year,which is the key area of energy conservation and emission reduction.However,in order to effectively control the total carbon emission,it is necessary to start from reducing the carbon emission intensity.At present,the carbon emission intensity of urban residential buildings in China has a large spatial difference.Therefore,it is necessary to first find out the main factors that cause the spatial difference of carbon emission intensity of urban residential buildings,and then formulate targeted alienation emission reduction strategies for business trip.In view of this,in combination with the characteristics of energy use of urban residential buildings,this paper selects building climate zoning and economic zoning as the entry point to study the spatial difference of carbon emission intensity of urban residential buildings,in which carbon emission intensity is divided into carbon emission per unit area and carbon emission per capita.In the specific research process,this paper first constructs the urban residential building carbon emission intensity calculation model,introduces the carbon emission coefficient calculation method of various types of energy,and analyzes the spatial difference of urban residential building carbon emission per unit area and per capita carbon emission.Secondly,the scope of building climate zoning and economic zoning is defined respectively,and then the regional differences of the two zones are analyzed through the thiel index to verify whether they will have an impact on the spatial difference of carbon emissions per unit area and per capita carbon emissions.On this basis,the influence degree is compared.Finally,considering the various factors may exist between the neighborhood spatial spillover effect,and the indirect influence on urban residential building carbon emissions intensity,in this paper,by introducing spatial econometric model,and the rate of urbanization,urban residents consumption level and other relevant factors into the model of spatial econometric analysis,according to the measurement results further analysis of building climate subarea and economic division of urban residential building carbon emissions per unit area and per capita carbon emissions space,the impact of differences and the influence the size of the comparison.Studies have shown that:(1)According to the calculation results of carbon emission intensity of urban residential buildings,carbon emission per unit area and per capita of urban residential buildings in northern heating areas are generally higher than that in non-heating areas.In the non-heating areas,the carbon emissions per unit area and per capita of urban residential buildings in the eastern coastal areas are generally higher than those in the central and western regions.(2)From the perspective of regional difference analysis,the influence of building climate zoning on the carbon emission per unit area and per capita carbon emission space difference of urban residential buildings is higher than that of economic zoning.The influence of building climate zoning on the per capita carbon emission of urban residential buildings is higher than that of unit area.The influence of economic zoning on the spatial difference of carbon emission per unit area of urban residential buildings is higher than that of per capita carbon emission.(3)From the perspective of spatial difference analysis,it is also concluded that the influence of building climate zoning on the carbon emission per unit area of urban residential buildings and the spatial difference of carbon emission per capita are both higher than that of economic zoning under the condition that various influencing factors may have spatial spillover effect.In addition,among all the influencing factors that are positively correlated with the carbon emission intensity of urban residential buildings,the urbanization rate has the highest impact on the spatial difference of carbon emission per unit area and per capita carbon emission of urban residential buildings.Among all the factors negatively related to the carbon emission intensity of urban residential buildings,the per capita living area has the highest impact on the spatial difference of carbon emission per unit area of urban residential buildings,and the energy consumption structure has the highest impact on the spatial difference of carbon emission per capita of urban residential buildings.
