Research On The Relationship Between Provincial Economic Development Level And Construction Industry Carbon Emission Based On Spatial Heterogeneity On Assembly

The rapid development of construction industry makes great contribution to promoting the economic growth of our country.But the construction industry as a representative of high energy consumption and high pollution industry.In the process of the development of the construction industry,there are problems such as increasing energy consumption and low energy utilization efficiency,which lead to the continuous rise of carbon emissions and adv erse impact on the ecological environment.In addition.China's economic development level and the carbon emission of the construction industry have regional differences,and the relevant policies on carbon emission reduction of the construction industry have different impacts on different provinces.Therefore,it is necessary to analyze the relationship between carbon emission of construction industry and economic development level from the perspective of heterogeneity.First of all,the associated carbon method is used to measure the provinces domain construction of carbon emissions in 2007-2016 values.and based on the calculation of construction carbon based data in-depth analysis of the spatial distribution features,the provincial construction of carbon emissions is divided into five types of carbon emissions,using standard deviation ellipse method analysis the provinces domain construction carbon spatial pattern of the space-time change and migration of the center of gravity of the trend.Secondly,in order to guarantee the construction both in seeking the optimal development speed,and to achieve a reasonable level construction carbon emissions and to seek optimal development construction carbon reduction method and keep construction speed,the spatial dependence of economic development level and trend of shift is analyzed,explore construction carbon emissions and shift trend of the economic development level is in the opposite direction changes.or changes in the same direction.Finally,give full consideration to the other factors that affect the construction of carbon emissions,and these factors as the control variables of the model.build the provincial economic development level and the construction spatial durbin model of carbon emissions,in-depth study on the relationship between them,and use the panel threshold model to investigate the level of economic development impact on the construction of carbon emissions of regional heterogeneity,get more specific and reliable results.The results tell us that the carbon emission of the construction industry in China's provinces shows a significant spatial agglomeration and an unbalanced development pattern.The carbon emission of the construction industry can be divided into five different types of carbon emission,the transition of the carbon emission of the construction industry in various provinces in different carbon emission areas is gradual,without any jump change,the carbon emission center of the construction industry is gradually moving to the southwest.China's provincial economic development level presents the characteristics of clustering and distribution of low-value clusters and high-value clusters,and the number of low-value clusters of provincial economic development level occupies a large proportion,which indicates that the spatial differentiation characteristics of China's provincial economic development level are obvious,the center of gravity of the economic development level is generally moving to the northwest,and the carbon emission center of the construction industry is separated from the center of gravity of the economic development level.there is a significant spatial heterogeneity relationship between the carbon emission of the construction industry and the economic development level.According to the above research results,positive countermeasures and Suggestions are provided for the carbon emission reduction of the construction industry in the province,so that the carbon emission of the construction industry and the economy develop in a coordinated direction.
