Research On The Driving Factors And Countermeasures Of Low-Carbon Construction In The Construction Industry Under The Background Of Double Carbon Goal

Carbon emissions from the construction industry account for more than half of China’s carbon emissions.To achieve the goals of "carbon peaking" and "carbon neutrality",China must achieve low-carbon development of the construction industry.The low-carbon development of the construction industry is faced with challenges such as large amount of carbon emissions,high energy intensity,extensive coverage and time constraints,and is affected by many driving factors.In order to scientifically and reasonably realize the low-carbon development of the construction industry,it is necessary to reduce the driving factors are identified,and corresponding countermeasures are proposed on this basis.By studying domestic and foreign data and literature,this thesis constructs an index system of driving factors of low carbonization in the construction industry.At the same time,this thesis combines the BP neural network with the DEMATEL method,and uses the BP neural network operation to overcome the problems of complicated calculation and strong subjectivity faced by the questionnaires and expert scoring methods in the traditional DEMATEL method,so it can be more objective.Drivers are identified.The BP-DEMATEL model uses the BP neural network to calculate the comprehensive influence matrix between each driving factor,and then uses the traditional DEMATEL method to analyze the centrality and causality of each driving factor in the comprehensive influence matrix,and finally identifies the cause driving factor and the effect driving factors.In order to improve the objectivity and scientificity of the results,the data in this article are all taken from official statistics.The results show that the strong causal factor for the low-carbon development of the construction industry is GDP,and the strong consequential factors are the number of patents and energy intensity.According to the identification results,suggestions and countermeasures for the low-carbon development of my country’s construction industry are put forward,providing theoretical support and scientific guidance for the low-carbon development countermeasures of the construction industry.
